164-655: The Baltimore & Annapolis Railroad (B&A) was an American railroad of central Maryland built in the 19th century to connect the cities of Baltimore and Annapolis. From 1897 to 1968 the railroad ran between Annapolis and Clifford along the north shore of the Severn River . From Clifford, just north of the present day Patapsco Light Rail Stop , it connected with the B&;O's Curtis Bay branch so that trains could travel to Baltimore , though from 1914 to 1950 it bypassed this to travel instead to Carrol Junction and then to
328-623: A Catholic convert who sought to provide a religious haven for Catholics persecuted in England. In 1632, Charles I of England granted Lord Baltimore a colonial charter , naming the colony after his wife, Henrietta Maria . In 1649, the Maryland General Assembly passed an Act Concerning Religion , which enshrined the principle of toleration . Religious strife was common in Maryland's early years, and Catholics remained
492-451: A Holiday Inn . At the same time, most of the old Shortline track between Linthicum and Westport was abandoned, except for a section between Baltimore Highlands and the B&;O Clifford interchange which was kept to handle freight to and from the B&O. The "new" (B&O-built) Annapolis Shortline ROW between Clifford and Westport was also retained for freight interchange, though this segment
656-507: A university , library system , music and dance conservatory , and art museum . Cumberland was Maryland's second-largest city in the 19th century. Nearby supplies of natural resources along with railroads fostered its growth into a major manufacturing center. The Progressive Era of the late 19th and early 20th centuries brought political reforms. In a series of laws passed between 1892 and 1908, reformers worked for standard state-issued ballots (rather than those distributed and marked by
820-402: A (nearly) continuous conductor running along the track that usually takes one of two forms: an overhead line , suspended from poles or towers along the track or from structure or tunnel ceilings, or a third rail mounted at track level and contacted by a sliding " pickup shoe ". Both overhead wire and third-rail systems usually use the running rails as the return conductor, but some systems use
984-638: A 1952 1200-horsepower diesel. In the same year, WIA sold the western part of their right-of-way in Annapolis to Wardour Bluff Apartments at the end of Shiley Street and to property owners at the end of Tolson Street. In 1986 WIA donated the Severn River Railroad Trestle to the Maryland Department of Natural Resources so that they could demolish it and 1989, it was declared a navigational hazard and what remained of it
1148-418: A M4.8 earthquake from Tewksbury in central New Jersey was felt slightly throughout Maryland. Railway electrification Railway electrification is the use of electric power for the propulsion of rail transport . Electric railways use either electric locomotives (hauling passengers or freight in separate cars), electric multiple units ( passenger cars with their own motors) or both. Electricity
1312-553: A century, carried on by the descendants of William Penn and Lord Baltimore—the Calvert family , which controlled Maryland, and the Penn family , which controlled Pennsylvania. The border dispute with Pennsylvania led to Cresap's War in the 1730s. Hostilities erupted in 1730 and escalated through the first half of the decade, culminating in the deployment of military forces by Maryland in 1736 and by Pennsylvania in 1737. The armed phase of
1476-464: A charter from King Charles I for the territory between Massachusetts to the north and Virginia to the immediate south. After Baltimore died in April 1632, the charter was granted to his son, Cecilius Calvert, 2nd Baron Baltimore (1605–1675), on June 20, 1632. Officially, the new "Maryland Colony" was named in honor of Henrietta Maria of France , wife of Charles I. Lord Baltimore initially proposed
1640-573: A higher total efficiency. Electricity for electric rail systems can also come from renewable energy , nuclear power , or other low-carbon sources, which do not emit pollution or emissions. Electric locomotives may easily be constructed with greater power output than most diesel locomotives. For passenger operation it is possible to provide enough power with diesel engines (see e.g. ' ICE TD ') but, at higher speeds, this proves costly and impractical. Therefore, almost all high speed trains are electric. The high power of electric locomotives also gives them
1804-541: A highly diversified economy spanning manufacturing, retail services, public administration, real estate, higher education, information technology, defense contracting, health care, and biotechnology. Maryland is one of the most multicultural states in the country; it is one of the six states where non-Whites compose a majority of the population , with the fifth-highest percentage of African Americans , and high numbers of residents born in Africa , Asia , Central America , and

#17328020905171968-467: A historical concern for double-stack rail transport regarding clearances with overhead lines but it is no longer universally true as of 2022 , with both Indian Railways and China Railway regularly operating electric double-stack cargo trains under overhead lines. Railway electrification has constantly increased in the past decades, and as of 2022, electrified tracks account for nearly one-third of total tracks globally. Railway electrification
2132-535: A minority, albeit in greater numbers than in any other English colony. Maryland's early settlements and population centers clustered around waterways that empty into the Chesapeake Bay . Its economy was heavily plantation-based and centered mostly on the cultivation of tobacco . Demand for cheap labor from Maryland colonists led to the importation of numerous indentured servants and enslaved Africans . In 1760, Maryland's current boundaries took form following
2296-537: A number of European countries, India, Saudi Arabia, eastern Japan, countries that used to be part of the Soviet Union, on high-speed lines in much of Western Europe (including countries that still run conventional railways under DC but not in countries using 16.7 Hz, see above). Most systems like this operate at 25 kV, although 12.5 kV sections exist in the United States, and 20 kV
2460-457: A power grid that is delivered to a locomotive, and within the locomotive, transformed and rectified to a lower DC voltage in preparation for use by traction motors. These motors may either be DC motors which directly use the DC or they may be three-phase AC motors which require further conversion of the DC to variable frequency three-phase AC (using power electronics). Thus both systems are faced with
2624-498: A relative lack of flexibility (since electric trains need third rails or overhead wires), and a vulnerability to power interruptions. Electro-diesel locomotives and electro-diesel multiple units mitigate these problems somewhat as they are capable of running on diesel power during an outage or on non-electrified routes. Different regions may use different supply voltages and frequencies, complicating through service and requiring greater complexity of locomotive power. There used to be
2788-481: A separate fourth rail for this purpose. In comparison to the principal alternative, the diesel engine , electric railways offer substantially better energy efficiency , lower emissions , and lower operating costs. Electric locomotives are also usually quieter, more powerful, and more responsive and reliable than diesel. They have no local emissions, an important advantage in tunnels and urban areas. Some electric traction systems provide regenerative braking that turns
2952-523: A series of newspaper editorials. Maryland's urban and rural communities had different experiences during the Great Depression . The " Bonus Army " marched through the state in 1932 on its way to Washington, D.C. Maryland instituted its first income tax in 1937 to generate revenue for schools and welfare. Passenger and freight steamboat service, once important throughout Chesapeake Bay and its many tributary rivers, ended in 1962. Baltimore
3116-693: A small connecting line was built between the A&;B and the AW&;B at the Bay Ridge Junction wye where the AW&B met the Annapolis and Bay Ridge Railroad . Business was slim in the early years, and in 1893 the railroad was sold to George Burnham Jr. and reorganized as the Baltimore & Annapolis Shortline the next year. Universally it was called simply “The Annapolis Shortline.” In 1906
3280-536: A small portion of the state's northeast corner (which drains into the Delaware River watershed). So prominent is the Chesapeake in Maryland's geography and economic life that there has been periodic agitation to change the state's official nickname to the "Bay State", a nickname that has been used by Massachusetts for decades. The highest point in Maryland, with an elevation of 3,360 feet (1,020 m),
3444-622: A state tobacco buy-out program in the 1990s. In an effort to reverse depopulation due to the loss of working-class industries, Baltimore initiated urban renewal projects in the 1960s with Charles Center and the Baltimore World Trade Center . Some resulted in the break-up of intact residential neighborhoods, producing social volatility, and some older residential areas around the harbor have had units renovated and have become popular with new populations. Maryland has an area of 12,406.68 square miles (32,133.2 km ) and

#17328020905173608-601: A terminal on Russell Street via the Camden Cutoff. It had periods of bust and boom that resulted in different owners, changed names and abandonment and sale. It started operation in 1897 as the Annapolis and Baltimore Shortline, but changed its name in 1893 to the Baltimore and Annapolis Shortline, or often just the Annapolis Shortline. In 1914 it changed to electric power and in 1921 it was purchased by
3772-418: A third rail. The key advantage of the four-rail system is that neither running rail carries any current. This scheme was introduced because of the problems of return currents, intended to be carried by the earthed (grounded) running rail, flowing through the iron tunnel linings instead. This can cause electrolytic damage and even arcing if the tunnel segments are not electrically bonded together. The problem
3936-470: A tool to gain popular support. The two years from 1644 to 1646 when Claiborne and his Puritan associates held sway were known as "The Plundering Time". They captured Jesuit priests, imprisoned them, then sent them back to England. In 1646, Leonard Calvert returned with troops, recaptured St. Mary's City, and restored order. The House of Delegates passed the "Act concerning Religion" in 1649 granting religious liberty to all Trinitarian Christians. In 1650,

It is the 42nd-largest and 9th-smallest state and is closest in size to the state of Hawaii [10,930.98 square miles (28,311.1 km )], the next smallest state. The next largest state is Maryland's neighbor, West Virginia , which is nearly twice the size of Maryland [24,229.76 square miles (62,754.8 km )]. Maryland possesses
4756-411: Is derived by using resistors which ensures that stray earth currents are kept to manageable levels. Power-only rails can be mounted on strongly insulating ceramic chairs to minimise current leak, but this is not possible for running rails, which have to be seated on stronger metal chairs to carry the weight of trains. However, elastomeric rubber pads placed between the rails and chairs can now solve part of

This and all other rubber-tyred metros that have a 1,435 mm ( 4 ft 8 + 1 ⁄ 2 in ) standard gauge track between the roll ways operate in the same manner. Railways and electrical utilities use AC as opposed to DC for the same reason: to use transformers , which require AC, to produce higher voltages. The higher
5084-526: Is electrified, companies often find that they need to continue use of diesel trains even if sections are electrified. The increasing demand for container traffic, which is more efficient when utilizing the double-stack car , also has network effect issues with existing electrifications due to insufficient clearance of overhead electrical lines for these trains, but electrification can be built or modified to have sufficient clearance, at additional cost. A problem specifically related to electrified lines are gaps in

5248-486: Is limited and losses are significantly higher. However, the higher voltages used in many AC electrification systems reduce transmission losses over longer distances, allowing for fewer substations or more powerful locomotives to be used. Also, the energy used to blow air to cool transformers, power electronics (including rectifiers), and other conversion hardware must be accounted for. Standard AC electrification systems use much higher voltages than standard DC systems. One of
5412-778: Is no longer exactly one-third of the grid frequency. This solved overheating problems with the rotary converters used to generate some of this power from the grid supply. In the US , the New York, New Haven, and Hartford Railroad , the Pennsylvania Railroad and the Philadelphia and Reading Railway adopted 11 kV 25 Hz single-phase AC. Parts of the original electrified network still operate at 25 Hz, with voltage boosted to 12 kV, while others were converted to 12.5 or 25 kV 60 Hz. In
5576-447: Is sufficient traffic, the reduced track and especially the lower engine maintenance and running costs exceed the costs of this maintenance significantly. Newly electrified lines often show a "sparks effect", whereby electrification in passenger rail systems leads to significant jumps in patronage / revenue. The reasons may include electric trains being seen as more modern and attractive to ride, faster, quieter and smoother service, and
5740-410: Is that the power-wasting resistors used in DC locomotives for speed control were not needed in an AC locomotive: multiple taps on the transformer can supply a range of voltages. Separate low-voltage transformer windings supply lighting and the motors driving auxiliary machinery. More recently, the development of very high power semiconductors has caused the classic DC motor to be largely replaced with
5904-894: Is the countrywide system. 3 kV DC is used in Belgium, Italy, Spain, Poland, Slovakia, Slovenia, South Africa, Chile, the northern portion of the Czech Republic, the former republics of the Soviet Union , and in the Netherlands on a few kilometers between Maastricht and Belgium. It was formerly used by the Milwaukee Road from Harlowton, Montana , to Seattle, across the Continental Divide and including extensive branch and loop lines in Montana, and by
6068-580: Is the development of powering trains and locomotives using electricity instead of diesel or steam power . The history of railway electrification dates back to the late 19th century when the first electric tramways were introduced in cities like Berlin , London , and New York City . In 1881, the first permanent railway electrification in the world was the Gross-Lichterfelde Tramway in Berlin , Germany. Overhead line electrification
6232-420: Is typically generated in large and relatively efficient generating stations , transmitted to the railway network and distributed to the trains. Some electric railways have their own dedicated generating stations and transmission lines , but most purchase power from an electric utility . The railway usually provides its own distribution lines, switches, and transformers . Power is supplied to moving trains with
6396-838: Is used on some narrow-gauge lines in Japan. On "French system" HSLs, the overhead line and a "sleeper" feeder line each carry 25 kV in relation to the rails, but in opposite phase so they are at 50 kV from each other; autotransformers equalize the tension at regular intervals. Various railway electrification systems in the late nineteenth and twentieth centuries utilised three-phase , rather than single-phase electric power delivery due to ease of design of both power supply and locomotives. These systems could either use standard network frequency and three power cables, or reduced frequency, which allowed for return-phase line to be third rail, rather than an additional overhead wire. The majority of modern electrification systems take AC energy from
6560-493: The 19th-most populous state and the fifth-most densely populated . Maryland's capital is Annapolis , and the most populous city is Baltimore . Maryland's coastline was first explored by Europeans in the 16th century. Prior to that, it was inhabited by several Native American tribes, mostly the Algonquian peoples . As one of the original Thirteen Colonies , Maryland was founded by George Calvert , 1st Baron Baltimore,

#17328020905178528-609: The settlement of a long-running border dispute with Pennsylvania. Many of its citizens played key political and military roles in the American Revolutionary War . Although it was a slave state , Maryland remained in the Union during the American Civil War , and its proximity to Washington D.C. and Virginia made it a significant strategic location . After the Civil War ended, Maryland took part in
8692-471: The 1980s. The B&A (by then nicknamed "The Bumble and Amble") purchased a diesel that it used to remain in freight service, serving as many as 40 different customers in 1963. It ran coal and building supplies to Annapolis until June 1968 when the Severn River Trestle was declared unsafe. It ceased operations across the trestle, but it never requested permission to abandon service there, and

Negotiations ensued after the problem was discovered in 1681. A compromise proposed by Charles II in 1682 was undermined by Penn's receiving the additional grant of what is now Delaware. Penn successfully argued that the Maryland charter entitled Lord Baltimore only to unsettled lands, and Dutch settlement in Delaware predated his charter. The dispute remained unresolved for nearly

That process was completed in 1908 and it changed its name to the Maryland Electric Railways Company , providing clean, comfortable, faster, and more frequent service. That same year, the Washington, Baltimore and Annapolis Electric Railway built an electric rail line between Baltimore and Washington that ran adjacent to, and just to

The land was provided along
11808-494: The ability to pull freight at higher speed over gradients; in mixed traffic conditions this increases capacity when the time between trains can be decreased. The higher power of electric locomotives and an electrification can also be a cheaper alternative to a new and less steep railway if train weights are to be increased on a system. On the other hand, electrification may not be suitable for lines with low frequency of traffic, because lower running cost of trains may be outweighed by
11972-516: The advantages of raising the voltage is that, to transmit certain level of power, lower current is necessary ( P = V × I ). Lowering the current reduces the ohmic losses and allows for less bulky, lighter overhead line equipment and more spacing between traction substations, while maintaining power capacity of the system. On the other hand, the higher voltage requires larger isolation gaps, requiring some elements of infrastructure to be larger. The standard-frequency AC system may introduce imbalance to

In 1975, following an adverse decision by an ICC administrative law judge, the courts found that B&A had illegally abandoned operations and the ICC eventually forced them to repair the bridge and resume operations to Glen Burnie, which happened sometime after 1979. In 1973, after trains stopped running due to the damaged bridge, State Senator Alfred J. Lipin proposed turning

Although one of the smallest states in the U.S., it features a variety of climates and topographical features that have earned it the moniker of America in Miniature . In a similar vein, Maryland's geography, culture, and history combine elements of
12464-410: The company began running motor-coaches between Baltimore and Annapolis, and expanded in 1941 with a line serving Fort Meade from both cities. They expanded again in 1943 with service to Brooklyn-Curtis Bay. By 1943 the motor-coaches were carrying 1,000,000 passenger. Following World War II, gasoline and cars came back, highway expansion followed and passenger rail service became unprofitable. By 1939
12628-451: The conflict ended in May 1738 with the intervention of King George II, who compelled the negotiation of a cease-fire. A provisional agreement had been established in 1732. Negotiations continued until a final agreement was signed in 1760. The agreement defined the border between Maryland and Pennsylvania as the line of latitude now known as the Mason–Dixon line . Maryland's border with Delaware
12792-525: The county line in Anne Arundel that used about 1000 feet of the B&A ROW, opened on August 20, 1992. That was followed by a 4-station extension to Linthicum on April 2, 1993, and an additional 2-station extension to Glen Burnie on June 20, 1993. Starting in early 1992, the state provided freight service to Quebecor Printing Inc. (formerly Alco-Gravure) in Glen Burnie via
12956-410: The distance they could transmit power. However, in the early 20th century, alternating current (AC) power systems were developed, which allowed for more efficient power transmission over longer distances. In the 1920s and 1930s, many countries worldwide began to electrify their railways. In Europe, Switzerland , Sweden , France , and Italy were among the early adopters of railway electrification. In
13120-523: The early 21st Century. The bulk of the right-of-way now serves as part of Baltimore's light rail system and as the Baltimore & Annapolis Trail . The Baltimore & Annapolis Railroad was chartered in 1880, by a group of New England promoters as the Annapolis and Baltimore Shortline and began running on March 3, 1887. This freight and passenger line was an integral link between Annapolis and Baltimore, transporting almost two million passengers per year until competition from nearby highways forced
13284-654: The eastern and western halves of Maryland were linked for the first time by the Chesapeake Bay Bridge , which replaced a nearby ferry service. Maryland's regions experienced economic changes following WWII. Heavy manufacturing declined in Baltimore. In Maryland's four westernmost counties, industrial, railroad, and coal mining jobs declined. On the lower Eastern Shore , family farms were bought up by major concerns and large-scale poultry farms and vegetable farming became prevalent. In Southern Maryland, tobacco farming nearly vanished due to suburban development and
13448-491: The election of a new pro-union governor and legislature, President Abraham Lincoln had a number of its pro-slavery politicians arrested, including the Mayor of Baltimore, George William Brown ; suspended several civil liberties, including habeas corpus ; and ordered artillery placed on Federal Hill overlooking Baltimore. In April 1861, Federal units and state regiments were attacked as they marched through Baltimore, sparking
13612-403: The electorate and immigrants comprised 15%, and the legislature had difficulty devising requirements against blacks that did not also disadvantage immigrants. The Progressive Era also brought reforms in working conditions for Maryland's labor force. In 1902, the state regulated conditions in mines ; outlawed child laborers under the age of 12; mandated compulsory school attendance; and enacted
13776-509: The electorate. Compared to some other states, blacks were better established both before and after the civil war. Nearly half the black population was free before the war, and some had accumulated property. Half the population lived in cities. Literacy was high among blacks and, as Democrats crafted means to exclude them, suffrage campaigns helped reach blacks and teach them how to resist. Whites did impose racial segregation in public facilities and Jim Crow laws, which effectively lasted until
13940-448: The electrification. Electric vehicles, especially locomotives, lose power when traversing gaps in the supply, such as phase change gaps in overhead systems, and gaps over points in third rail systems. These become a nuisance if the locomotive stops with its collector on a dead gap, in which case there is no power to restart. This is less of a problem in trains consisting of two or more multiple units coupled together, since in that case if
14104-404: The end of funding. Most electrification systems use overhead wires, but third rail is an option up to 1,500 V. Third rail systems almost exclusively use DC distribution. The use of AC is usually not feasible due to the dimensions of a third rail being physically very large compared with the skin depth that AC penetrates to 0.3 millimetres or 0.012 inches in a steel rail. This effect makes
14268-591: The experiment was curtailed. In 1970 the Ural Electromechanical Institute of Railway Engineers carried out calculations for railway electrification at 12 kV DC , showing that the equivalent loss levels for a 25 kV AC system could be achieved with DC voltage between 11 and 16 kV. In the 1980s and 1990s 12 kV DC was being tested on the October Railway near Leningrad (now Petersburg ). The experiments ended in 1995 due to
14432-500: The fact that electrification often goes hand in hand with a general infrastructure and rolling stock overhaul / replacement, which leads to better service quality (in a way that theoretically could also be achieved by doing similar upgrades yet without electrification). Whatever the causes of the sparks effect, it is well established for numerous routes that have electrified over decades. This also applies when bus routes with diesel buses are replaced by trolleybuses. The overhead wires make
14596-482: The first rail line to reach the Ohio River from the eastern seaboard. The state remained in the Union during the American Civil War , due in significant part to demographics and Federal intervention. The 1860 census, held shortly before the outbreak of the civil war, showed that 49% of Maryland's African Americans were free . Governor Thomas Holliday Hicks suspended the state legislature, and to help ensure
14760-554: The following months. Work pulling up the rails started in September 1991 and was completed on February 18, 1992. In 1985, the Anne Arundel County Parks department started work on a rail-trail south of Dorsey Avenue. In 1990, work was completed on the Baltimore & Annapolis Rail Trail and it opened on October 7. The light rail line along the old B&A right-of-way opened in three parts in 1992 and 1993. A three-station extension to Patapsco , just across
14924-1012: The general power grid. This is especially useful in mountainous areas where heavily loaded trains must descend long grades. Central station electricity can often be generated with higher efficiency than a mobile engine/generator. While the efficiency of power plant generation and diesel locomotive generation are roughly the same in the nominal regime, diesel motors decrease in efficiency in non-nominal regimes at low power while if an electric power plant needs to generate less power it will shut down its least efficient generators, thereby increasing efficiency. The electric train can save energy (as compared to diesel) by regenerative braking and by not needing to consume energy by idling as diesel locomotives do when stopped or coasting. However, electric rolling stock may run cooling blowers when stopped or coasting, thus consuming energy. Large fossil fuel power stations operate at high efficiency, and can be used for district heating or to produce district cooling , leading to
15088-411: The high cost of the electrification infrastructure. Therefore, most long-distance lines in developing or sparsely populated countries are not electrified due to relatively low frequency of trains. Network effects are a large factor with electrification. When converting lines to electric, the connections with other lines must be considered. Some electrifications have subsequently been removed because of
15252-545: The land for $ 450,000 on the condition that they could end passenger rail service because they were running an annual operating deficit of $ 100,000. At the time, the B&A was running 49 passenger trains and 3 freight trains between Baltimore and Annapolis. In September 1949, the B&A formally requested permission to abandon passenger car service. In December 1949, the Public Services Commission granted their request to end passenger rail service but, as
15416-500: The larger Washington, Baltimore and Annapolis Electric Railway (WB&A). The WB&A went bankrupt in 1935 and the railroad emerged from the bankruptcy as the Baltimore & Annapolis Railroad. B&A electric passenger operation between the two cities continued until 1950 when the section of rail between Carrol Junction and Clifford Junction was purchased for the Baltimore-Washington Parkway. At that time
15580-421: The legal restrictions on religious organizations' owning property. The royal charter granted Maryland the land north of the Potomac River up to the 40th parallel . A problem arose when Charles II granted a charter for Pennsylvania . The grant defined Pennsylvania's southern border as identical to Maryland's northern border, the 40th parallel. But the grant indicated that Charles II and William Penn assumed
15744-406: The line ended. The WCLR had operated under the direct ownership of the county prior to its ownership by the B&A. The right of way continued to be owned by the county and was initially leased to the B&A for a period of 30 years. Operations by the B&A started shortly after filing. The B&A's operation and major ownership of railroad lines in the Carolinas ended on December 18, 2015, with
15908-702: The line ran immediately west/south of the Curtis Bay branch, passed under the Curtis Bay branch and then ran parallel to the South Baltimore branch, over the Western Maryland Railway and Gwynns Falls through Westport to Carrol Junction and the Camden Cutoff. During its heyday, the years between 1918 and the late 1920s, the B&A transported as many as 1,750,000 passengers per year between Baltimore and Annapolis. Trains left every hour from 6 am through 11 pm (during rush hours ,
16072-470: The line would shrink through a series of abandonments and sell its property to various entities. In 1979, Anne Arundel County purchased the no longer used section of the 66-foot (20 m) wide right of way from Dorsey Road in Glen Burnie to the north shore of the Severn River for the purpose of creating the Baltimore & Annapolis Trail and park. In 1983, the B&A sold the right-of-way from
16236-431: The line, which the company could not afford to perform. Horry County had placed the railroad in default over lack of lease payments during this time period. The B&A has not operated publicly under the name Baltimore and Annapolis Railroad Company during its time owning and operating rail lines in the Carolinas, but does roster one former C&O EMD SW9 in B&A paint (#87), and a former N&W boxcar lettered for
16400-497: The losses (saving 2 GWh per year per 100 route-km; equalling about €150,000 p.a.). The line chosen is one of the lines, totalling 6000 km, that are in need of renewal. In the 1960s the Soviets experimented with boosting the overhead voltage from 3 to 6 kV. DC rolling stock was equipped with ignitron -based converters to lower the supply voltage to 3 kV. The converters turned out to be unreliable and
16564-422: The maximum power that can be transmitted, also can be responsible for electrochemical corrosion due to stray DC currents. Electric trains need not carry the weight of prime movers , transmission and fuel. This is partly offset by the weight of electrical equipment. Regenerative braking returns power to the electrification system so that it may be used elsewhere, by other trains on the same system or returned to
16728-615: The name Carolina Southern Railroad (reporting marks CALA). All public business outside of federal railroad filings were performed under the auspices of the CALA. In June 2001, the Waccamaw Coast Line Railroad (WCLR), a new division of the B&A, filed to operate 14.1 miles (22.7 km) of railroad owned by Horry County, SC between the current terminus of the CALA in Conway, SC and the city of Myrtle Beach, SC where
16892-513: The name "Crescentia", the land of growth or increase, but "the King proposed Terra Mariae [Mary Land], which was concluded on and inserted in the bill." The original capital of Maryland was St. Mary's City , on the north shore of the Potomac River , and the county surrounding it, the first erected/created in the province, was first called Augusta Carolina, after the King, and later named St. Mary's County. Lord Baltimore's first settlers arrived in
17056-445: The nation's first workers' compensation law. The workers' compensation law was overturned in the courts, but was redrafted and finally enacted in 1910. The Great Baltimore Fire of 1904 burned for more than 30 hours, destroying 1,526 buildings and spanning 70 city blocks. More than 1,231 firefighters worked to bring the blaze under control. With the nation's entry into World War I in 1917, new military bases such as Camp Meade ,
17220-402: The need for overhead wires between those stations. Maintenance costs of the lines may be increased by electrification, but many systems claim lower costs due to reduced wear-and-tear on the track from lighter rolling stock. There are some additional maintenance costs associated with the electrical equipment around the track, such as power sub-stations and the catenary wire itself, but, if there
17384-648: The new colony in March 1634, with his younger brother the Honorable Leonard Calvert (1606–1647), as first provincial Governor of Maryland . They made their first permanent settlement at St. Mary's City in what is now St. Mary's County . They purchased the site from the paramount chief of the region, who was eager to establish trade. St. Mary's became the first capital of Maryland, and remained so for 60 years until 1695. More settlers soon followed. Their tobacco crops were successful and quickly made
17548-527: The new colony profitable. However, given the incidence of malaria , yellow fever , and typhoid , life expectancy in Maryland was about 10 years less than in New England . Maryland was founded to provide a haven for England's Roman Catholic minority. Although Maryland was the most heavily Catholic of the English mainland colonies, the religion was still in the minority, consisting of less than 10% of
17712-694: The north shore of the Potomac River from Montgomery and Prince George's counties, as well as from Fairfax County and Alexandria on the south shore of the Potomac in Virginia ; however, the land donated by the Commonwealth of Virginia was later returned to that state by the District of Columbia retrocession in 1846. Influenced by a changing economy, revolutionary ideals, and preaching by ministers, numerous planters in Maryland freed their slaves in
17876-675: The parties); obtained closed voting booths to prevent party workers from "assisting" voters; initiated primary elections to keep party bosses from selecting candidates; and had candidates listed without party symbols, which discouraged the illiterate from participating. These measures worked against ill-educated whites and blacks. Blacks resisted such efforts, with suffrage groups conducting voter education. Blacks defeated three efforts to disenfranchise them, making alliances with immigrants to resist various Democratic campaigns. Disenfranchisement bills in 1905, 1907, and 1911 were rebuffed, in large part because of black opposition. Blacks comprised 20% of
18040-507: The passage of federal civil rights legislation in the mid-1960s. Baltimore grew significantly during the Industrial Revolution , due in large part to its seaport and good railroad connections, attracting European immigrant labor. Many manufacturing businesses were established in the Baltimore area after the Civil War. Baltimore businessmen, including Johns Hopkins , Enoch Pratt , George Peabody , and Henry Walters , founded notable city institutions that bear their names, including respectively
18204-505: The phase separation between the electrified sections powered from different phases, whereas high voltage would make the transmission more efficient. UIC conducted a case study for the conversion of the Bordeaux-Hendaye railway line (France), currently electrified at 1.5 kV DC, to 9 kV DC and found that the conversion would allow to use less bulky overhead wires (saving €20 million per 100 route-km) and lower
18368-482: The principle of partus sequitur ventrem , by which children took the social status of their mothers, a principle of slave law that was adopted throughout the colonies, following Virginia in 1662. Many of the free black families migrated to Delaware, where land was cheaper. As the flow of indentured laborers to the colony decreased with improving economic conditions in England, planters in Maryland imported thousands more slaves and racial caste lines hardened. Maryland
18532-508: The problem by insulating the running rails from the current return should there be a leakage through the running rails. The Expo and Millennium Line of the Vancouver SkyTrain use side-contact fourth-rail systems for their 650 V DC supply. Both are located to the side of the train, as the space between the running rails is occupied by an aluminum plate, as part of stator of the linear induction propulsion system used on
18696-452: The purpose of a trail and together with other Jaycees they cleared the ROW for hiking and advocated to make it a county-owned trail and park. In 1976, after losing their case to abandon the whole railroad; the B&A, Anne Arundel County and Annapolis requested permission to abandon the 15 miles between Glen Burnie, MD, and Annapolis. Permission was granted in 1978 and the rail south of Glen Burnie
18860-493: The rail line into a trail. The MTA was already planning to use the right-of-way for transit if the abandonment was allowed and Lipin's constituents didn't want it turned into a busway; but Lipin noted that even if had transit, it could still have a trail too. The next year, while service was down and the abandonment cases were litigated, the Severna Park Jaycees leased the unused portion of the track through town for
19024-528: The railroad was seeking permission to replace passenger rail with buses. In 1947, the city began to negotiate the purchase of about 4000 feet of the railroad to Baltimore for use as part of the Baltimore-Washington Parkway (BW Parkway). The land ran from Russell Street to just north of the B&O's Curtis Bay Branch and consisted of the line that the B&A had used to access its Baltimore terminal. The B&A agreed to sell and clear
19188-538: The railroads' closure. It was the second railroad to serve Annapolis and provided a faster connection to Baltimore, taking a more direct path along the north shore of the Severn River and then crossing the river into Annapolis. The railroad transformed the once-secluded banks of the Severn to a series of suburban communities. The railroad started as a steam powered line running from a station in Annapolis, on Bladen Street just south of St. John's College, crossing
19352-410: The resistance per unit length unacceptably high compared with the use of DC. Third rail is more compact than overhead wires and can be used in smaller-diameter tunnels, an important factor for subway systems. The London Underground in England is one of few networks that uses a four-rail system. The additional rail carries the electrical return that, on third-rail and overhead networks, is provided by
19516-570: The revenue obtained for freight and passenger traffic. Different systems are used for urban and intercity areas; some electric locomotives can switch to different supply voltages to allow flexibility in operation. Six of the most commonly used voltages have been selected for European and international standardisation. Some of these are independent of the contact system used, so that, for example, 750 V DC may be used with either third rail or overhead lines. There are many other voltage systems used for railway electrification systems around
19680-498: The running rails. On the London Underground, a top-contact third rail is beside the track, energized at +420 V DC , and a top-contact fourth rail is located centrally between the running rails at −210 V DC , which combine to provide a traction voltage of 630 V DC . The same system was used for Milan 's earliest underground line, Milan Metro 's line 1 , whose more recent lines use an overhead catenary or
19844-572: The sale of all but one mile of its CALA rail lines to the R.J. Corman Railroad Group , operating under a new railroad for this line, R. J. Corman Railroad Company/Carolina Lines, LLC (RJCS). The one additional mile that remains under the ownership of the CALA was leased to the RJCS. The company also retained ownership of the Conway, SC depot and other land assets along the right of way. The railroad lines had been out of service since 2011 due to Federal Railroad Administration (FRA) orders to repair bridges along
20008-426: The sale of the B&A's right-of-way, one of the sticking points was that the B&A wanted to retain exclusive rights to run freight on the line at night. They relented on this, but when the sale went through they were still hoping to continue to run freight with the rolling stock they retained. They did not get the freight contract and so began looking elsewhere to use their rolling stock and invest their profits from
20172-484: The sale of the right-of-way. On February 9, 1995, the Baltimore and Annapolis Railroad Company, by that time merely an entity on paper with a locomotive, filed to acquire and operate approximately 75.9 miles (122.1 km) of rail line from the Mid Atlantic Railroad , which operated track between Mullin's, SC and Whiteville NC, and between Chadbourn, NC and Conway, SC. This line was operated under
20336-467: The same task: converting and transporting high-voltage AC from the power grid to low-voltage DC in the locomotive. The difference between AC and DC electrification systems lies in where the AC is converted to DC: at the substation or on the train. Energy efficiency and infrastructure costs determine which of these is used on a network, although this is often fixed due to pre-existing electrification systems. Both
20500-476: The song " The Star-Spangled Banner " was written by Francis Scott Key ; it was later adopted as the national anthem. National Road, later renamed U.S. Route 40 , was authorized in 1817 as the federal highway, and ran from Baltimore to St. Louis . The Baltimore and Ohio Railroad (B&O), the first chartered railroad in the United States, opened its first section of track for regular operation in 1830 between Baltimore and Ellicott City , and in 1852 it became
20664-489: The south shore of the Severn River to Annapolis Street, as well as the trestle across the Severn, to the Wardour Improvement Association (WIA), an Annapolis homeowners association, for $ 1. In the spring of 1984, the railroad — consisting of the 6 mile long, 70-foot wide right-of-way, a 1950 diesel-engine, a flat car, a motorized track-inspection car and some miscellaneous property —
20828-692: The south. Portions of Maryland are included in various official and unofficial geographic regions. For example, the Delmarva Peninsula is composed of the Eastern Shore counties of Maryland, the entire state of Delaware , and the two counties that make up the Eastern Shore of Virginia , whereas the westernmost counties of Maryland are considered part of Appalachia . Much of the Baltimore–Washington corridor lies just south of
20992-531: The state commissioned a study of options for turning the rail line, perhaps as far as Annapolis, into a light rail line. Negotiations started shortly thereafter. In May 1991, Maryland bought the still active part of the B&A railroad for the southern leg of the light rail system for $ 9 million, but the state had to promise to maintain freight operations to appease the Interstate Commerce Commission. The railroad ceased operation in
21156-559: The state, and the counties east of the bay are known collectively as the Eastern Shore . Most of the state's waterways are part of the Chesapeake Bay watershed, with the exceptions of a tiny portion of extreme western Garrett County (drained by the Youghiogheny River as part of the watershed of the Mississippi River ), the eastern half of Worcester County (which drains into Maryland's Atlantic coastal bays), and
21320-401: The state-owned Canton Railroad . Once light rail trains started operations to Linthicum however the freight rail service had to moved to nights. In 1996, MTA commissioned a study to analyze the environmental impact of extending the light rail 0.75 miles (1.21 km) along the B&A right-of-way, by then the B&A Trail, as far south as 1st Avenue in Glen Burnie. During negotiations for
21484-569: The steep approaches to the tunnel. The system was also used for suburban electrification in East London and Manchester , now converted to 25 kV AC. It is now only used for the Tyne and Wear Metro . In India, 1,500 V DC was the first electrification system launched in 1925 in Mumbai area. Between 2012 and 2016, the electrification was converted to 25 kV 50 Hz, which
21648-443: The supply grid, requiring careful planning and design (as at each substation power is drawn from two out of three phases). The low-frequency AC system may be powered by separate generation and distribution network or a network of converter substations, adding the expense, also low-frequency transformers, used both at the substations and on the rolling stock, are particularly bulky and heavy. The DC system, apart from being limited as to
21812-694: The three-phase induction motor fed by a variable frequency drive , a special inverter that varies both frequency and voltage to control motor speed. These drives can run equally well on DC or AC of any frequency, and many modern electric locomotives are designed to handle different supply voltages and frequencies to simplify cross-border operation. Five European countries – Germany, Austria, Switzerland, Norway and Sweden – have standardized on 15 kV 16 + 2 ⁄ 3 Hz (the 50 Hz mains frequency divided by three) single-phase AC. On 16 October 1995, Germany, Austria and Switzerland changed from 16 + 2 ⁄ 3 Hz to 16.7 Hz which
21976-575: The through traffic to non-electrified lines. If through traffic is to have any benefit, time-consuming engine switches must occur to make such connections or expensive dual mode engines must be used. This is mostly an issue for long-distance trips, but many lines come to be dominated by through traffic from long-haul freight trains (usually running coal, ore, or containers to or from ports). In theory, these trains could enjoy dramatic savings through electrification, but it can be too costly to extend electrification to isolated areas, and unless an entire network
22140-467: The total population. In 1642, a number of Puritans left Virginia for Maryland and founded the city of Providence, now called Annapolis , on the western shore of the upper Chesapeake Bay . A dispute with traders from Virginia over Kent Island in the Chesapeake led to armed conflict. In 1644, William Claiborne , a Puritan, seized Kent Island while his associate, the pro-Parliament Puritan Richard Ingle , took over St. Mary's. Both used religion as
22304-553: The traditionally Southern and Tidewater culture that previously dominated most of the state. Agricultural tracts gave way to residential communities, some of them carefully planned such as Columbia , St. Charles , and Montgomery Village . Concurrently the Interstate Highway System was built throughout the state, most notably I-95 , I-695 , and the Capital Beltway , altering travel patterns. In 1952,
22468-466: The train stops with one collector in a dead gap, another multiple unit can push or pull the disconnected unit until it can again draw power. The same applies to the kind of push-pull trains which have a locomotive at each end. Power gaps can be overcome in single-collector trains by on-board batteries or motor-flywheel-generator systems. In 2014, progress is being made in the use of large capacitors to power electric vehicles between stations, and so avoid
22632-713: The train's kinetic energy back into electricity and returns it to the supply system to be used by other trains or the general utility grid. While diesel locomotives burn petroleum products, electricity can be generated from diverse sources, including renewable energy . Historically, concerns of resource independence have played a role in the decision to electrify railway lines. The landlocked Swiss confederation which almost completely lacks oil or coal deposits but has plentiful hydropower electrified its network in part in reaction to supply issues during both World Wars. Disadvantages of electric traction include: high capital costs that may be uneconomic on lightly trafficked routes,
22796-529: The trains left every 30 minutes). Because of its strong performance, the neighboring WB&A bought the Annapolis Shortline in 1921 and it became part of the WB&;A system in which it was called the North Shore Line . Afterward, Shortline trains were routed over the WB&A between Linthicum and the WB&A's new Baltimore terminal at the corner of Howard & Lombard Streets, now the site of
22960-413: The transmission and conversion of electric energy involve losses: ohmic losses in wires and power electronics, magnetic field losses in transformers and smoothing reactors (inductors). Power conversion for a DC system takes place mainly in a railway substation where large, heavy, and more efficient hardware can be used as compared to an AC system where conversion takes place aboard the locomotive where space
23124-470: The tyres do not conduct the return current, the two guide bars provided outside the running ' roll ways ' become, in a sense, a third and fourth rail which each provide 750 V DC , so at least electrically it is a four-rail system. Each wheel set of a powered bogie carries one traction motor . A side sliding (side running) contact shoe picks up the current from the vertical face of each guide bar. The return of each traction motor, as well as each wagon ,
23288-432: The voltage, the lower the current for the same power (because power is current multiplied by voltage), and power loss is proportional to the current squared. The lower current reduces line loss, thus allowing higher power to be delivered. As alternating current is used with high voltages. Inside the locomotive, a transformer steps the voltage down for use by the traction motors and auxiliary loads. An early advantage of AC
23452-405: The weight of an on-board transformer. Increasing availability of high-voltage semiconductors may allow the use of higher and more efficient DC voltages that heretofore have only been practical with AC. The use of medium-voltage DC electrification (MVDC) would solve some of the issues associated with standard-frequency AC electrification systems, especially possible supply grid load imbalance and
23616-534: The west of, the B&A tracks between Linthicum and Clifford. Despite the upgrade, steam-powered trains continued to operate on the line until 1919. Unlike most electric railways of its time, which employed a low voltage Direct Current electrification, the line installed a 6,600 volt, 25 cycle, single phase Alternating Current electrification system newly developed by the Westinghouse Electric & Manufacturing Company . The pioneering AC system
23780-556: The wide Severn River estuary on a long timber trestle , and on to Clifford on the B&O line, where it used the B&O tracks to terminate at Camden Station in Baltimore. Because the A&B Shortline created an almost straight line southeast from Baltimore it snatched much of the Baltimore-Annapolis trade away from the Annapolis, Washington & Baltimore Railroad on which passengers had to change trains at Odenton or Annapolis Junction. At some point prior to 1892,
23944-532: The world, and the list of railway electrification systems covers both standard voltage and non-standard voltage systems. The permissible range of voltages allowed for the standardised voltages is as stated in standards BS EN 50163 and IEC 60850. These take into account the number of trains drawing current and their distance from the substation. 1,500 V DC is used in Japan, Indonesia, Hong Kong (parts), Ireland, Australia (parts), France (also using 25 kV 50 Hz AC ) ,
24108-534: The world, including China , India , Japan , France , Germany , and the United Kingdom . Electrification is seen as a more sustainable and environmentally friendly alternative to diesel or steam power and is an important part of many countries' transportation infrastructure. Electrification systems are classified by three main parameters: Selection of an electrification system is based on economics of energy supply, maintenance, and capital cost compared to
24272-421: Was a major war production center during World War II . The biggest operations were Bethlehem Steel 's Fairfield Yard, which built Liberty ships ; and Glenn Martin , an aircraft manufacturer. Maryland experienced population growth following World War II. Beginning in the 1960s, as suburban growth took hold around Washington, D.C. and Baltimore, the state began to take on a more mid-Atlantic culture as opposed to
24436-489: Was a six-mile (9.7 km) stub from the B&O Junction near Cherry Hill to Dorsey Road in Glen Burnie with occasional runs farther south to deliver sand or coal. In June 1972, Tropical Storm Agnes washed out the B&A's Patapsco River Bridge. As a result, the B&A stopped operating south of the Patapsco River. Alco-Gravure, which owned a printing plant in Glen Burnie served by the B&A, quickly sued to force
24600-408: Was abandoned. In 1973, the Baltimore & Annapolis Railroad's public bus system was absorbed by Maryland Transit Administration (MTA) as Route 14 . The company continued as a charter bus service but that ceased in 1982. The state began eyeing the B&A for rapid transit passenger service to Baltimore as early as 1963, but it would take decades for that to happen, and over the intervening years
24764-561: Was based on a Transpeninsular Line and the Twelve-Mile Circle around New Castle. Most of the English colonists arrived in Maryland as indentured servants , and had to serve a several years' term as laborers to pay for their passage. In the early years, the line between indentured servants and African slaves or laborers was fluid, and white and black laborers commonly lived and worked together, and formed unions. Mixed-race children born to white mothers were considered free by
24928-633: Was built in 1904 to provide power to the railroad and renovated in 1989 when the trail was built. As Part of state highway project, a bike lane along route 50 and the Severn River Bridge, connected the trail to Annapolis. It now hosts an antique shop. In between it hosted an ice house, a restaurant and the Anne Arundel County Historic Society's headquarters. Maryland Maryland ( US : / ˈ m ɛr ɪ l ə n d / MERR -il-ənd )
25092-444: Was considered a strategic Union victory and a turning point of the war. A new state constitution in 1864 abolished slavery and Maryland was first recognized as a "Free State" in that context. Following passage of constitutional amendments that granted voting rights to freedmen , in 1867 the state extended suffrage to non-white males. The Democratic Party rapidly regained power in the state from Republicans . Democrats replaced
25256-429: Was demanded by city leaders along the line, required them to continue freight service. The B&A announced the end of passenger service that month. To prepare for the loss of passenger rail service the B&A began offering scheduled commuter bus service between Baltimore, Glen Burnie, and Annapolis, along with its passenger rail service. A proposal for the line to be acquired by the B&O Railroad for freight service
25420-502: Was discarded when the B&O's studies concluded it would require $ 1.35 million in infrastructure improvements to bring it up to Class 1 railroad standards. The B&A ended rail passenger service on February 5, 1950, and used the money from the sale of part of the line to purchase 11 more buses (creating a fleet of 42 for the route) and a new diesel electric locomotive. It reorganized into two companies, one that ran passenger buses and one that ran freight rail. The old bypass
25584-437: Was exacerbated because the return current also had a tendency to flow through nearby iron pipes forming the water and gas mains. Some of these, particularly Victorian mains that predated London's underground railways, were not constructed to carry currents and had no adequate electrical bonding between pipe segments. The four-rail system solves the problem. Although the supply has an artificially created earth point, this connection
25748-496: Was first applied successfully by Frank Sprague in Richmond, Virginia in 1887-1888, and led to the electrification of hundreds of additional street railway systems by the early 1890s. The first electrification of a mainline railway was the Baltimore and Ohio Railroad's Baltimore Belt Line in the United States in 1895–96. The early electrification of railways used direct current (DC) power systems, which were limited in terms of
25912-446: Was later abandoned in 1979. Gross receipts for the WB&A began to decline almost as soon as it bought the B&A in 1921. For the next decade, the WB&A only survived because of a law exempting it from taxes. In January 1931, the extension of the law failed to pass by one vote and the line went into receivership. The line remained in operation for four more years until it officially ceased on August 20, 1935. The WB&A
26076-518: Was less than fully successful, however, and in 1914, new owners switched to DC. When it did, the B&O was wary of a high-voltage, as both the WB&A and Shortline then used 3300v AC over its tracks, overhead line between the Clifford interchange and Camden Station ; so the B&O built a new line for the Shortline between Clifford Junction and its mainline at Russell Street. Leaving Clifford,
26240-617: Was one of the thirteen colonies that revolted against British rule in the American Revolution . Near the end of the American Revolutionary War (1775–1783), on February 2, 1781, Maryland became the last and 13th state to approve the ratification of the Articles of Confederation and Perpetual Union , first proposed in 1776 and adopted by the Second Continental Congress in 1778, which brought into being
26404-562: Was removed north of the Curtis Bay Branch and part of it was replaced with the BW Parkway later that year; and the electric wires were removed from the remaining line. In 1961, there was a 25-day experiment with commuter rail to Camden Station from Harundale, but it proved to be too slow. In addition the line continued to provide excursion rides (including bringing Santa to town or providing rides on Ferndale Day every May) into
26568-616: Was sold at public auction with scrap dealers buying most of the rolling stock . Selling the B&A rail for scrap would have cut off the capital from rail travel, so state officials and the Naval Academy convinced the bondholders not to scrap the B&A line. The right-of-way and some equipment were instead bought by the Bondholders Protective Society who then formed the Baltimore and Annapolis Railroad Company . This company negotiated an agreement with
26732-501: Was sold to Ken Pippin for less than $ 1 million. At that point it served a lumber company and two paper companies in Anne Arundel County. On September 16, 1987, to celebrate the 100th Anniversary of the B&A, B&A number 50 made one final run on the line from Linthicum Station to Camden Station. It was then donated to and retired at the B&O Railroad Museum . The freight line continued to operate with
26896-434: Was torn down. The draw and sections of the bridge north and south of it had been removed by 1983. MTA had been talking about turning the B&A into a transit line since at the early 1960s, but it took 20 years to become reality. In 1967 a Maryland Mass transit steering committee was formed and quickly identified the B&A line as a good candidate for a mass transit system to Harundale or perhaps as far as Annapolis. In 1987
