107-547: George B. Armstrong, manager of the Chicago Post Office, is generally credited with being the founder of the concept of en route mail sorting aboard trains which became the Railway Mail Service. Mail had been carried in locked pouches aboard trains prior to Armstrong's involvement with the system, but there had been no organized system of sorting mail en route, to have mail prepared for delivery when

214-408: A crank on a driving axle. Steam locomotives have been phased out in most parts of the world for economical and safety reasons, although many are preserved in working order by heritage railways . Electric locomotives draw power from a stationary source via an overhead wire or third rail . Some also or instead use a battery . In locomotives that are powered by high-voltage alternating current ,

321-586: A dining car . Some lines also provide over-night services with sleeping cars . Some long-haul trains have been given a specific name . Regional trains are medium distance trains that connect cities with outlying, surrounding areas, or provide a regional service, making more stops and having lower speeds. Commuter trains serve suburbs of urban areas, providing a daily commuting service. Airport rail links provide quick access from city centres to airports . High-speed rail are special inter-city trains that operate at much higher speeds than conventional railways,

428-731: A fourth rail system in 1890 on the City and South London Railway , now part of the London Underground Northern line . This was the first major railway to use electric traction . The world's first deep-level electric railway, it runs from the City of London , under the River Thames , to Stockwell in south London. The first practical AC electric locomotive was designed by Charles Brown , then working for Oerlikon , Zürich. In 1891, Brown had demonstrated long-distance power transmission, using three-phase AC , between

535-542: A funicular railway at the Hohensalzburg Fortress in Austria. The line originally used wooden rails and a hemp haulage rope and was operated by human or animal power, through a treadwheel . The line is still operational, although in updated form and is possibly the oldest operational railway. Wagonways (or tramways ) using wooden rails, hauled by horses, started appearing in the 1550s to facilitate

642-492: A hydro-electric plant at Lauffen am Neckar and Frankfurt am Main West, a distance of 280 km (170 mi). Using experience he had gained while working for Jean Heilmann on steam–electric locomotive designs, Brown observed that three-phase motors had a higher power-to-weight ratio than DC motors and, because of the absence of a commutator , were simpler to manufacture and maintain. However, they were much larger than

749-431: A steam engine that provides adhesion. Coal , petroleum , or wood is burned in a firebox , boiling water in the boiler to create pressurized steam. The steam travels through the smokebox before leaving via the chimney or smoke stack. In the process, it powers a piston that transmits power directly through a connecting rod (US: main rod) and a crankpin (US: wristpin) on the driving wheel (US main driver) or to

856-469: A transformer in the locomotive converts the high-voltage low-current power to low-voltage high current used in the traction motors that power the wheels. Modern locomotives may use three-phase AC induction motors or direct current motors. Under certain conditions, electric locomotives are the most powerful traction. They are also the cheapest to run and provide less noise and no local air pollution. However, they require high capital investments both for

963-469: A 1914 Mail RPO, that is classed as a "combine" car, having sections for the RPO, Railway Express Agency and twenty seats for paying passengers. Currently, it is the only Railway Post Office car known to be operational and currently certified for operation on commercial rail. The Osceola and St Croix Valley Railway (division of MTM/reporting mark MNTX) operates the car as part of its tour line, actually "catching

1070-605: A buffer force of at least 400,000 pounds. This requirement was doubled to 800,000 pounds in a 1938 revision of the standards. The requirements were again strengthened in 1945 with specifications that precluded the use of aluminium for framing and major structural components. The 1945 revisions also included a requirement for end posts to prevent telescoping in the event of a collision. Railway car manufacturers adopted these requirements and carried them through to all other models of passenger cars that they built. The 800,000-lb buffer load and end post requirements were later adopted by

1177-637: A clerk scoring only 96% accuracy would likely receive a warning from the Railway Mail Service division superintendent. Interurban and Streetcar systems were also known to operate RPOs. The Boston Elevated Railway car was noted for making circuits of the city to pick up mail. In the United States, RPO cars (also known as mail cars or postal cars) were equipped and staffed to handle most back-end postal processing functions. First class mail, magazines and newspapers were all sorted, cancelled when necessary, and dispatched to post offices in towns along

1284-455: A device ( U.S. patent 61,584 ) was awarded to L. F. Ward of Elyria, Ohio, on January 29, 1867. This was about a year after apparatus for picking up and setting down mailbags without stopping was installed for equivalent UK TPOs at Slough and Maidenhead, having first been patented in UK in 1838 by Nathaniel Worsdell. With the train often operating at 70 mph or more, a postal clerk would have

1391-550: A diesel locomotive from the company in 1909. The world's first diesel-powered locomotive was operated in the summer of 1912 on the Winterthur–Romanshorn railway in Switzerland, but was not a commercial success. The locomotive weight was 95 tonnes and the power was 883 kW with a maximum speed of 100 km/h (62 mph). Small numbers of prototype diesel locomotives were produced in a number of countries through

1498-478: A double track plateway, erroneously sometimes cited as world's first public railway, in south London. William Jessop had earlier used a form of all-iron edge rail and flanged wheels successfully for an extension to the Charnwood Forest Canal at Nanpantan , Loughborough, Leicestershire in 1789. In 1790, Jessop and his partner Outram began to manufacture edge rails. Jessop became a partner in

1605-437: A large turning radius in its design. While high-speed rail is most often designed for passenger travel, some high-speed systems also offer freight service. Since 1980, rail transport has changed dramatically, but a number of heritage railways continue to operate as part of living history to preserve and maintain old railway lines for services of tourist trains. A train is a connected series of rail vehicles that move along

1712-498: A larger locomotive named Galvani , exhibited at the Royal Scottish Society of Arts Exhibition in 1841. The seven-ton vehicle had two direct-drive reluctance motors , with fixed electromagnets acting on iron bars attached to a wooden cylinder on each axle, and simple commutators . It hauled a load of six tons at four miles per hour (6 kilometers per hour) for a distance of one and a half miles (2.4 kilometres). It

1819-504: A local post office, with the cancel giving the train number, endpoint cities of the RPO route, the date, and RMS Railway Mail Service or PTS Postal Transportation Service between the killer bars . Collecting such cancellations is a pastime of many philatelists and postal history researchers. The Railway Mail Service organization within the Post Office Department existed between 1864 and September 30, 1948. It

1926-423: A locomotive. This involves one or more powered vehicles being located at the front of the train, providing sufficient tractive force to haul the weight of the full train. This arrangement remains dominant for freight trains and is often used for passenger trains. A push–pull train has the end passenger car equipped with a driver's cab so that the engine driver can remotely control the locomotive. This allows one of

2033-428: A mail slot on the side of the car, so that mail could actually be deposited in the car, much like using the corner mail box, while the train was stopped at a station. Those desiring the fastest delivery would bring their letters to the train station for dispatch on the RPO, knowing that overnight delivery would be virtually assured. The mail handled in this manner received a cancellation just as if it had been mailed at

2140-560: A number of configurations to hold mail pouches, racks and a sorting table as needed for specific routes. The fixtures were also designed so they could be folded away completely to provide a wholly open space to carry general baggage and express shipments as needed by the railroads. Harrison followed through with manufacturing his design at a factory he opened in Fond du Lac, Wisconsin in 1881. The July 1, 1862, Pacific Railroad Act signed by President Lincoln established government funding for

2247-477: A number of trains per hour (tph). Passenger trains can usually be into two types of operation, intercity railway and intracity transit. Whereas intercity railway involve higher speeds, longer routes, and lower frequency (usually scheduled), intracity transit involves lower speeds, shorter routes, and higher frequency (especially during peak hours). Intercity trains are long-haul trains that operate with few stops between cities. Trains typically have amenities such as

2354-676: A piece of circular rail track in Bloomsbury , London, the Catch Me Who Can , but never got beyond the experimental stage with railway locomotives, not least because his engines were too heavy for the cast-iron plateway track then in use. The first commercially successful steam locomotive was Matthew Murray 's rack locomotive Salamanca built for the Middleton Railway in Leeds in 1812. This twin-cylinder locomotive

2461-465: A pivotal role in the development and widespread adoption of the steam locomotive. His designs considerably improved on the work of the earlier pioneers. He built the locomotive Blücher , also a successful flanged -wheel adhesion locomotive. In 1825 he built the locomotive Locomotion for the Stockton and Darlington Railway in the northeast of England, which became the first public steam railway in

2568-420: A pouch of mail ready to be dispatched as the train passed the station. In a co-ordinated movement, the catcher arm was swung out to catch the hanging mail pouch while the clerk stood in the open doorway. The mail pouch had a strap around the middle, and the strap was tightened in preparation for pickup with an approximately equivalent weight of mail in either end of the pouch to prevent the heavier end from pulling

2675-589: A railway mail train in its Atrium. The interior fixtures are from a de-commissioned mail car. The exterior portion of the Railway Post Office train was created by Smithsonian artisans. Effective August 15, 1955, the fifteen divisions of the Postal Transportation Service were eliminated and the mail routes divided among the same Postal Regions into which Post Offices were classified. Railway post office In Canada and

2782-439: A revival in recent decades due to road congestion and rising fuel prices, as well as governments investing in rail as a means of reducing CO 2 emissions . Smooth, durable road surfaces have been made for wheeled vehicles since prehistoric times. In some cases, they were narrow and in pairs to support only the wheels. That is, they were wagonways or tracks. Some had grooves or flanges or other mechanical means to keep

2889-457: A separate compartment) express and baggage. Railway mail clerks were subjected to stringent training and regular testing of details regarding their handling of the mail. On a given RPO route, each clerk was expected to know not only the post offices and rail junctions along the route, but also specific local delivery details within each of the larger cities served by the route. Periodic testing demanded both accuracy and speed in sorting mail, and

2996-739: A single lever to control both engine and generator in a coordinated fashion, and was the prototype for all diesel–electric locomotive control systems. In 1914, world's first functional diesel–electric railcars were produced for the Königlich-Sächsische Staatseisenbahnen ( Royal Saxon State Railways ) by Waggonfabrik Rastatt with electric equipment from Brown, Boveri & Cie and diesel engines from Swiss Sulzer AG . They were classified as DET 1 and DET 2 ( de.wiki ). The first regular used diesel–electric locomotives were switcher (shunter) locomotives . General Electric produced several small switching locomotives in

3103-466: A somewhat uniform color scheme regardless of the railroad that owned or operated them. Most were painted white with trim in either buff, red or blue, which made the cars stand out from the other cars. By the 1890s, this practice had waned as railroads painted their RPO cars to match the rest of their passenger equipment. One RPO car that was displayed at the 1893 World's Columbian Exposition in Chicago

3210-407: A standard. Following SNCF's successful trials, 50 Hz, now also called industrial frequency was adopted as standard for main-lines across the world. Earliest recorded examples of an internal combustion engine for railway use included a prototype designed by William Dent Priestman . Sir William Thomson examined it in 1888 and described it as a "Priestman oil engine mounted upon a truck which

3317-632: A terminus about one-half mile (800 m) away. A funicular railway was also made at Broseley in Shropshire some time before 1604. This carried coal for James Clifford from his mines down to the River Severn to be loaded onto barges and carried to riverside towns. The Wollaton Wagonway , completed in 1604 by Huntingdon Beaumont , has sometimes erroneously been cited as the earliest British railway. It ran from Strelley to Wollaton near Nottingham . The Middleton Railway in Leeds , which

3424-408: A wheel. This was a large stationary engine , powering cotton mills and a variety of machinery; the state of boiler technology necessitated the use of low-pressure steam acting upon a vacuum in the cylinder, which required a separate condenser and an air pump . Nevertheless, as the construction of boilers improved, Watt investigated the use of high-pressure steam acting directly upon a piston, raising

3531-531: Is a means of transport using wheeled vehicles running in tracks , which usually consist of two parallel steel rails . Rail transport is one of the two primary means of land transport , next to road transport . It is used for about 8% of passenger and freight transport globally, thanks to its energy efficiency and potentially high speed . Rolling stock on rails generally encounters lower frictional resistance than rubber-tyred road vehicles, allowing rail cars to be coupled into longer trains . Power

3638-410: Is a single, self-powered car, and may be electrically propelled or powered by a diesel engine . Multiple units have a driver's cab at each end of the unit, and were developed following the ability to build electric motors and other engines small enough to fit under the coach. There are only a few freight multiple units, most of which are high-speed post trains. Steam locomotives are locomotives with

The restored 1927 AT&SF Railway #74 RPO car is displayed at the Pacific Southwest Railway Museum in Campo (San Diego County), California. For the permanent exhibition, Mail by Rail, the Smithsonian National Postal Museum re-created

3852-399: Is dominant. Electro-diesel locomotives are built to run as diesel–electric on unelectrified sections and as electric locomotives on electrified sections. Alternative methods of motive power include magnetic levitation , horse-drawn, cable , gravity, pneumatics and gas turbine . A passenger train stops at stations where passengers may embark and disembark. The oversight of the train is

3959-430: Is one of the last known examples of the early white color scheme. As the development of passenger cars progressed, so too did the development of RPO cars. The first plans for RPO car designs were based on light baggage car frames and bodies, which sometimes resulted in catastrophe for RMS employees when the trains were involved in accidents. From 1900 to 1906 some 70 workers were killed in train wrecks while on duty in

4066-408: Is usually provided by diesel or electrical locomotives . While railway transport is capital-intensive and less flexible than road transport, it can carry heavy loads of passengers and cargo with greater energy efficiency and safety. Precursors of railways driven by human or animal power have existed since antiquity, but modern rail transport began with the invention of the steam locomotive in

4173-556: Is worked on a temporary line of rails to show the adaptation of a petroleum engine for locomotive purposes." In 1894, a 20 hp (15 kW) two axle machine built by Priestman Brothers was used on the Hull Docks . In 1906, Rudolf Diesel , Adolf Klose and the steam and diesel engine manufacturer Gebrüder Sulzer founded Diesel-Sulzer-Klose GmbH to manufacture diesel-powered locomotives. Sulzer had been manufacturing diesel engines since 1898. The Prussian State Railways ordered

4280-523: The Erie . By 1869 when the Railway Mail Service was officially inaugurated, the system had expanded to virtually all of the major railroads of the United States , and the country was divided into six operating divisions. A superintendent was over each division, all under the direction of George B. Armstrong, who had been summoned from Chicago to Washington, D.C. , to become general superintendent of

4494-432: The U.S. Post Office Department (USPOD) to carry mail aboard high-speed passenger trains. The Railway Mail Service enforced various standardized designs on RPOs. A number of railway companies maintained nominally unprofitable passenger routes, having found that their financial losses from moving people were more than offset by transporting the mail on such passenger routes. The world's first official carriage of mail by rail

4601-692: The United Kingdom at the beginning of the 19th century. The first passenger railway, the Stockton and Darlington Railway , opened in 1825. The quick spread of railways throughout Europe and North America, following the 1830 opening of the first intercity connection in England, was a key component of the Industrial Revolution . The adoption of rail transport lowered shipping costs compared to water transport, leading to "national markets" in which prices varied less from city to city. In

4708-615: The United Kingdom , South Korea , Scandinavia, Belgium and the Netherlands. The construction of many of these lines has resulted in the dramatic decline of short-haul flights and automotive traffic between connected cities, such as the London–Paris–Brussels corridor, Madrid–Barcelona, Milan–Rome–Naples, as well as many other major lines. High-speed trains normally operate on standard gauge tracks of continuously welded rail on grade-separated right-of-way that incorporates

4815-414: The overhead lines and the supporting infrastructure, as well as the generating station that is needed to produce electricity. Accordingly, electric traction is used on urban systems, lines with high traffic and for high-speed rail. Diesel locomotives use a diesel engine as the prime mover . The energy transmission may be either diesel–electric , diesel-mechanical or diesel–hydraulic but diesel–electric

4922-458: The puddling process in 1784. In 1783 Cort also patented the rolling process , which was 15 times faster at consolidating and shaping iron than hammering. These processes greatly lowered the cost of producing iron and rails. The next important development in iron production was hot blast developed by James Beaumont Neilson (patented 1828), which considerably reduced the amount of coke (fuel) or charcoal needed to produce pig iron. Wrought iron

5029-418: The rotary phase converter , enabling electric locomotives to use three-phase motors whilst supplied via a single overhead wire, carrying the simple industrial frequency (50 Hz) single phase AC of the high-voltage national networks. An important contribution to the wider adoption of AC traction came from SNCF of France after World War II. The company conducted trials at AC 50 Hz, and established it as

5136-540: The 1880s, railway electrification began with tramways and rapid transit systems. Starting in the 1940s, steam locomotives were replaced by diesel locomotives . The first high-speed railway system was introduced in Japan in 1964, and high-speed rail lines now connect many cities in Europe , East Asia , and the eastern United States . Following some decline due to competition from cars and airplanes, rail transport has had

5243-521: The 1930s (the famous " 44-tonner " switcher was introduced in 1940) Westinghouse Electric and Baldwin collaborated to build switching locomotives starting in 1929. In 1929, the Canadian National Railways became the first North American railway to use diesels in mainline service with two units, 9000 and 9001, from Westinghouse. Although steam and diesel services reaching speeds up to 200 km/h (120 mph) were started before

5350-508: The 1960s in Europe, they were not very successful. The first electrified high-speed rail Tōkaidō Shinkansen was introduced in 1964 between Tokyo and Osaka in Japan. Since then high-speed rail transport, functioning at speeds up to and above 300 km/h (190 mph), has been built in Japan, Spain, France , Germany, Italy, the People's Republic of China, Taiwan (Republic of China),

5457-464: The 40 km Burgdorf–Thun line , Switzerland. Italian railways were the first in the world to introduce electric traction for the entire length of a main line rather than a short section. The 106 km Valtellina line was opened on 4 September 1902, designed by Kandó and a team from the Ganz works. The electrical system was three-phase at 3 kV 15 Hz. In 1918, Kandó invented and developed

5564-491: The American continent. By the 1880s, railway post office routes were operating on the vast majority of passenger trains in the United States. A complex network of interconnected routes allowed mail to be transported and delivered in a remarkably short time. As many as a dozen clerks might work in a single RPO car, although fewer would be required if part of the car was used for transport of previously sorted mail or (often in

5671-530: The Butterley Company in 1790. The first public edgeway (thus also first public railway) built was Lake Lock Rail Road in 1796. Although the primary purpose of the line was to carry coal, it also carried passengers. These two systems of constructing iron railways, the "L" plate-rail and the smooth edge-rail, continued to exist side by side until well into the early 19th century. The flanged wheel and edge-rail eventually proved its superiority and became

5778-514: The DC motors of the time and could not be mounted in underfloor bogies : they could only be carried within locomotive bodies. In 1894, Hungarian engineer Kálmán Kandó developed a new type 3-phase asynchronous electric drive motors and generators for electric locomotives. Kandó's early 1894 designs were first applied in a short three-phase AC tramway in Évian-les-Bains (France), which was constructed between 1896 and 1898. In 1896, Oerlikon installed

5885-449: The POD began experimenting with a highway version of the RPO to serve the same purposes along routes where passenger train service was not available. These highway post office (HPO) vehicles were initially intended to supplement RPO service, but in the 1950s and 1960s, HPOs often replaced railway post office cars after passenger train service was discontinued. The last interurban RPO service

5992-544: The POD cancelled all "mail by rail" contracts, electing to move all first class mail via air and other classes by road (truck) transport. This announcement had a devastating effect on passenger train revenues; the Santa Fe, for example, lost $ 35 million (US) in annual business, and led directly to the ending of many passenger rail routes. After 113 years of railway post office operation, the last surviving railway post office running on rails between New York and Washington, D.C.

6099-470: The RMS to handle the large increase in mail volume. The Railway Mail Service reached its peak in the 1920s, then began a gradual decline with the discontinuance of RPO service on branchlines and secondary routes. After 1942, Highway Post Office (HPO) service was utilized to continue en route sorting after discontinuance of some railway post office operations. As highway mail transportation became more prevalent,

6206-493: The RPOs, leading to demands for stronger steel cars. The RMS developed its first standards for car design in 1891 to address some of these issues. In 1912, the Railway Mail Service developed a set of strength requirements for new cars in an effort to push the car building companies into using steel for the cars' major structural components and underframes. The core of the requirements was that each car should be able to withstand

6313-515: The Railway Mail Service was redesignated as the Postal Transportation Service. Abandonment of routes accelerated in the late 1950s and early 1960s, and many of the remaining lines were discontinued in 1967. On June 30, 1974, the Cleveland and Cincinnati highway post office, the last HPO route, was discontinued. The last railway post office operated between New York and Washington, D.C., on June 30, 1977. A large bust and monument to Armstrong

6420-472: The United States, a railway post office , commonly abbreviated as RPO , was a railroad car that was normally operated in passenger service and used specifically for staff to sort mail en route, in order to speed delivery. The RPO was staffed by highly trained Railway Mail Service postal clerks, and was off-limits to the passengers on the train . From the middle of the 19th century, many American railroads earned substantial revenues through contracts with

6634-615: The cars are kept in operational condition. In 1933, Chicago, Burlington and Quincy Railroad rebuilt one of its baggage cars into a replica of the first RPOs that were used on the Hannibal and St. Joseph Railroad in 1862. The railroad displayed the car in several cities along the railroad; it now resides at the Patee House Museum in St. Joseph, Missouri . The Minnesota Transportation Museum (MTM) maintains Northern Pacific #1102,

6741-435: The clerks see the addresses on the mail they sorted, first by improving the reflectors in the 1880s, then calling for discontinuance of oil lamps in the 1890s and the first experiments with electric lighting in 1912. Clerks' safety was also of great concern to the RMS, with the first comprehensive statistics on work-related injuries published in 1877. Through the second half of the 19th century, most RPO cars were painted in

6848-633: The construction of a railroad from the Missouri River to the Pacific Ocean in order to open a main line mail route across the western frontier. The act was officially entitled "AN ACT to aid in the construction of a railroad and telegraph line from the Missouri river to the Pacific Ocean, and to secure to the government the use of the same for postal, military, and other purposes". The Act authorized government-funded railroad mail routes across

6955-430: The duty of a guard/train manager/conductor . Passenger trains are part of public transport and often make up the stem of the service, with buses feeding to stations. Passenger trains provide long-distance intercity travel, daily commuter trips, or local urban transit services, operating with a diversity of vehicles, operating speeds, right-of-way requirements, and service frequency. Service frequencies are often expressed as

7062-402: The end of the 19th century, because they were cleaner compared to steam-driven trams which caused smoke in city streets. In 1784 James Watt , a Scottish inventor and mechanical engineer, patented a design for a steam locomotive . Watt had improved the steam engine of Thomas Newcomen , hitherto used to pump water out of mines, and developed a reciprocating engine in 1769 capable of powering

7169-471: The end of the 19th century, improving the quality of steel and further reducing costs. Thus steel completely replaced the use of iron in rails, becoming standard for all railways. The first passenger horsecar or tram , Swansea and Mumbles Railway , was opened between Swansea and Mumbles in Wales in 1807. Horses remained the preferable mode for tram transport even after the arrival of steam engines until

7276-527: The engine by one power stroke. The transmission system employed a large flywheel to even out the action of the piston rod. On 21 February 1804, the world's first steam-powered railway journey took place when Trevithick's unnamed steam locomotive hauled a train along the tramway of the Penydarren ironworks, near Merthyr Tydfil in South Wales . Trevithick later demonstrated a locomotive operating upon

7383-475: The era of great expansion of railways that began in the late 1860s. Steel rails lasted several times longer than iron. Steel rails made heavier locomotives possible, allowing for longer trains and improving the productivity of railroads. The Bessemer process introduced nitrogen into the steel, which caused the steel to become brittle with age. The open hearth furnace began to replace the Bessemer process near

7490-522: The first commercial example of the system on the Lugano Tramway . Each 30-tonne locomotive had two 110 kW (150 hp) motors run by three-phase 750 V 40 Hz fed from double overhead lines. Three-phase motors run at a constant speed and provide regenerative braking , and are well suited to steeply graded routes, and the first main-line three-phase locomotives were supplied by Brown (by then in partnership with Walter Boveri ) in 1899 on

7597-670: The first shipment of mail carried on a train (sorted at the endpoints and carried in a bag on the train with other baggage) occurred in 1831 on the South Carolina Rail Road . Other sources state that the first official contract to regularly carry mail on a train was made with the Baltimore and Ohio Railroad in either 1834 or 1835. The United States Congress officially designated all railroads as official postal routes on July 7, 1838. Similar services were introduced on Canadian railroads in 1859. The railway post office

7704-581: The idea of having mail processed and distributed while the mail was on board, en route in mail cars. With the assistance of Schuyler Colfax , Speaker of the House at the time, and A. N. Zevely , Third Assistant Postmaster General, Armstrong was authorized to test his ideas. In 1869, the Railway Mail Service (RMS), headed by George B. Armstrong , was officially inaugurated to handle the transportation and sorting of mail aboard trains. Armstrong

7811-428: The lighter end off the catcher arm. As the inbound pouch slammed into the catcher arm, the clerk kicked the outbound mail pouch out of the car, making certain to kick it far enough that it was not sucked back under the train. Outbound pouches of first class mail were sealed with a locked strap for security. Larger sacks with optional provisions for locking were used for newspapers, magazines, and parcel post.

7918-1230: The limit being regarded at 200 to 350 kilometres per hour (120 to 220 mph). High-speed trains are used mostly for long-haul service and most systems are in Western Europe and East Asia. Magnetic levitation trains such as the Shanghai maglev train use under-riding magnets which attract themselves upward towards the underside of a guideway and this line has achieved somewhat higher peak speeds in day-to-day operation than conventional high-speed railways, although only over short distances. Due to their heightened speeds, route alignments for high-speed rail tend to have broader curves than conventional railways, but may have steeper grades that are more easily climbed by trains with large kinetic energy. High kinetic energy translates to higher horsepower-to-ton ratios (e.g. 20 horsepower per short ton or 16 kilowatts per tonne); this allows trains to accelerate and maintain higher speeds and negotiate steep grades as momentum builds up and recovered in downgrades (reducing cut and fill and tunnelling requirements). Since lateral forces act on curves, curvatures are designed with

8025-757: The local post office would retrieve the pouches and sacks and deliver them to the post office. In the 1950s the Budd Company offered two versions of its self-propelled diesel RDC with RPO: the RDC-3 combine and the RDC-4 (a baggage/mail/express only unit). These models were purchased by the New York Central , Boston & Maine , New Haven Railroad , Rock Island , Pacific Great Eastern , Northern Pacific , Canadian Pacific Railway , Canadian National and Minneapolis & St. Louis . Most RPO cars had

8132-429: The locomotive-hauled train's drawbacks to be removed, since the locomotive need not be moved to the front of the train each time the train changes direction. A railroad car is a vehicle used for the haulage of either passengers or freight. A multiple unit has powered wheels throughout the whole train. These are used for rapid transit and tram systems, as well as many both short- and long-haul passenger trains. A railcar

8239-571: The mail on the fly" as a part of its regular runs. As part of the 40th anniversary of the end of RPO service, Minnesota Transportation Museum will be placing #1102 on display at Saint Paul Union Depot as part of its "Last Mail Train" for National Train Day, 6 May 2017. At the end of the day, Great Northern 400 , Northern Pacific Railway RPO #1102 and two coaches will be departing Union Depot as Train #1 bound for Osceola, Wisconsin. It will be hauling commemorative envelopes and cards to be sent all across

8346-510: The mail pouches reached their destination city. In response to Armstrong's request to experiment with the concept, the first railway post office (RPO) began operating on the Chicago and North Western Railway between Chicago and Clinton, Iowa , on August 28, 1864. The concept was successful, and was expanded to other railroads operating from Chicago, including the Chicago, Burlington and Quincy , Chicago and Rock Island , Pennsylvania and

8453-569: The main portion of the B&;O to the new line to New York through a series of tunnels around the edges of Baltimore's downtown. Electricity quickly became the power supply of choice for subways, abetted by the Sprague's invention of multiple-unit train control in 1897. By the early 1900s most street railways were electrified. The London Underground , the world's oldest underground railway, opened in 1863, and it began operating electric services using

8560-649: The majority of this service consisted of one or more cars at the head end of passenger trains, many railways operated solid mail trains between major cities; these solid mail trains would often carry 300 tons of mail daily. After 1948, the railway post office network began its decline although it remained the principal intercity mail transportation and distribution function within the Post Office Department (POD). There were 794 RPO lines operating over 161,000 miles of railroad in that year. Only 262 RPO routes were still operating by January 1, 1962. In 1942,

8667-433: The mid-1920s. The Soviet Union operated three experimental units of different designs since late 1925, though only one of them (the E el-2 ) proved technically viable. A significant breakthrough occurred in 1914, when Hermann Lemp , a General Electric electrical engineer, developed and patented a reliable direct current electrical control system (subsequent improvements were also patented by Lemp). Lemp's design used

8774-479: The needs of the Post Office rather than the needs of the traveling public. In 1890, 5,800 postal railway clerks provided service over 154,800 miles (249,100 km) of railroad. By 1907, over 14,000 clerks were providing service over 203,000 miles (327,000 km) of railroad. When the post office began handling parcel post in 1913, Terminal Railway Post Office operations were established in major cities by

8881-412: The noise they made on the tracks. There are many references to their use in central Europe in the 16th century. Such a transport system was later used by German miners at Caldbeck , Cumbria , England, perhaps from the 1560s. A wagonway was built at Prescot , near Liverpool , sometime around 1600, possibly as early as 1594. Owned by Philip Layton, the line carried coal from a pit near Prescot Hall to

8988-525: The possibility of a smaller engine that might be used to power a vehicle. Following his patent, Watt's employee William Murdoch produced a working model of a self-propelled steam carriage in that year. The first full-scale working railway steam locomotive was built in the United Kingdom in 1804 by Richard Trevithick , a British engineer born in Cornwall . This used high-pressure steam to drive

9095-474: The postal railway service. Armstrong served only two years as general superintendent before resigning because of failing health. He died in Chicago on May 5, 1871, two days after his resignation. Armstrong's successor in Chicago, George Bangs , was appointed as the second general superintendent of the postal railway service. Bangs encouraged the use of fast mail trains, trains made up entirely of mail cars, traveling on expedited schedules designed to accommodate

9202-428: The route. Registered mail was also handled. The foreman in charge was required to carry a regulation pistol while on duty to discourage theft of the mail. Because of the physical and mental demands placed on RPO clerks, the Railway Mail Service pushed the adoption of standardized floor plans and fixtures for all RPO cars, with the first plans published in 1885. The RMS also pressed for improved lighting fixtures to help

9309-441: The standard for railways. Cast iron used in rails proved unsatisfactory because it was brittle and broke under heavy loads. The wrought iron invented by John Birkinshaw in 1820 replaced cast iron. Wrought iron, usually simply referred to as "iron", was a ductile material that could undergo considerable deformation before breaking, making it more suitable for iron rails. But iron was expensive to produce until Henry Cort patented

9416-475: The time, was Liverpool and Manchester Railway , built in 1830. Steam power continued to be the dominant power system in railways around the world for more than a century. The first known electric locomotive was built in 1837 by chemist Robert Davidson of Aberdeen in Scotland, and it was powered by galvanic cells (batteries). Thus it was also the earliest battery-electric locomotive. Davidson later built

9523-543: The track. Propulsion for the train is provided by a separate locomotive or from individual motors in self-propelled multiple units. Most trains carry a revenue load, although non-revenue cars exist for the railway's own use, such as for maintenance-of-way purposes. The engine driver (engineer in North America) controls the locomotive or other power cars, although people movers and some rapid transits are under automatic control. Traditionally, trains are pulled using

9630-491: The train's arrival at St. Joseph. This service lasted approximately one year. The first permanent Railway Post Office route was established on August 28, 1864, between Chicago, Illinois , and Clinton, Iowa . This service is distinguished from the 1862 operation because mail was sorted to and received from each post office along the route, as well as major post offices beyond the route's end-points. George B. Armstrong, assistant postmaster at Chicago, originally came up with

9737-471: The transport of ore tubs to and from mines and soon became popular in Europe. Such an operation was illustrated in Germany in 1556 by Georgius Agricola in his work De re metallica . This line used "Hund" carts with unflanged wheels running on wooden planks and a vertical pin on the truck fitting into the gap between the planks to keep it going the right way. The miners called the wagons Hunde ("dogs") from

9844-629: The wheels on track. For example, evidence indicates that a 6 to 8.5 km long Diolkos paved trackway transported boats across the Isthmus of Corinth in Greece from around 600 BC. The Diolkos was in use for over 650 years, until at least the 1st century AD. Paved trackways were also later built in Roman Egypt . In 1515, Cardinal Matthäus Lang wrote a description of the Reisszug ,

9951-559: The world in 1825, although it used both horse power and steam power on different runs. In 1829, he built the locomotive Rocket , which entered in and won the Rainhill Trials . This success led to Stephenson establishing his company as the pre-eminent builder of steam locomotives for railways in Great Britain and Ireland, the United States, and much of Europe. The first public railway which used only steam locomotives, all

10058-512: Was a soft material that contained slag or dross . The softness and dross tended to make iron rails distort and delaminate and they lasted less than 10 years. Sometimes they lasted as little as one year under high traffic. All these developments in the production of iron eventually led to the replacement of composite wood/iron rails with superior all-iron rails. The introduction of the Bessemer process , enabling steel to be made inexpensively, led to

10165-602: Was accomplished by the distribution of weight between a number of wheels. Puffing Billy is now on display in the Science Museum in London, and is the oldest locomotive in existence. In 1814, George Stephenson , inspired by the early locomotives of Trevithick, Murray and Hedley, persuaded the manager of the Killingworth colliery where he worked to allow him to build a steam-powered machine. Stephenson played

10272-514: Was built by Siemens. The tram ran on 180 volts DC, which was supplied by running rails. In 1891 the track was equipped with an overhead wire and the line was extended to Berlin-Lichterfelde West station . The Volk's Electric Railway opened in 1883 in Brighton , England. The railway is still operational, thus making it the oldest operational electric railway in the world. Also in 1883, Mödling and Hinterbrühl Tram opened near Vienna in Austria. It

10379-706: Was built in 1758, later became the world's oldest operational railway (other than funiculars), albeit now in an upgraded form. In 1764, the first railway in the Americas was built in Lewiston, New York . In the late 1760s, the Coalbrookdale Company began to fix plates of cast iron to the upper surface of the wooden rails. This allowed a variation of gauge to be used. At first only balloon loops could be used for turning, but later, movable points were taken into use that allowed for switching. A system

10486-674: Was by the United Kingdom's General Post Office in November 1830, using adapted railway carriages on the Liverpool and Manchester Railway . Sorting of mail en-route first occurred in the United Kingdom with the introduction of the travelling post office in 1838 on the Grand Junction Railway , following the introduction of the Railways (Conveyance of Mails) Act 1838 . In the United States, some references suggest that

10593-516: Was discontinued on June 30, 1977. The last route with a railway post office title was actually a boat run that lasted a year longer. This boat railway post office was the Lake Winnipesaukee RPO operating between The Weirs, New Hampshire , and Bear Island on Lake Winnipesaukee . The final date it operated with a postmark was September 30, 1978. Many RPO cars have been preserved in railroad museums across North America; some of

10700-474: Was introduced in the United States on July 28, 1862, using converted baggage cars on the Hannibal and St. Joseph Railroad (which also delivered the first letter to the Pony Express ). Purpose-built Railway Post Office (RPO) cars entered service on this line a few weeks after the service was initiated. They were used by staff to separate mail for connection with a westbound stagecoach departing soon after

10807-548: Was introduced in which unflanged wheels ran on L-shaped metal plates, which came to be known as plateways . John Curr , a Sheffield colliery manager, invented this flanged rail in 1787, though the exact date of this is disputed. The plate rail was taken up by Benjamin Outram for wagonways serving his canals, manufacturing them at his Butterley ironworks . In 1803, William Jessop opened the Surrey Iron Railway ,

10914-489: Was light enough to not break the edge-rails track and solved the problem of adhesion by a cog-wheel using teeth cast on the side of one of the rails. Thus it was also the first rack railway . This was followed in 1813 by the locomotive Puffing Billy built by Christopher Blackett and William Hedley for the Wylam Colliery Railway, the first successful locomotive running by adhesion only. This

11021-414: Was operated by Pacific Electric Railway on its route between Los Angeles and San Bernardino, California . When the post office made a controversial policy change to process mail in large regional "sectional centers," mail was now sorted by large machines, not by people, and the remaining railway post office routes, along with all highway post office routes, were phased out of service. In September 1967

11128-528: Was promoted from a supervisory position in the Chicago post office following his experiments in 1864 with a converted route agent's car on runs between Chicago and Clinton, Iowa. RPO car interiors, which at first consisted of solid wood furniture and fixtures, were soon redesigned to support their new purpose. In 1879, an RMS employee named Charles R. Harrison developed a new set of fixtures that soon gained widespread use. Harrison's design consisted of hinged, cast-iron fixtures that could be unfolded and set up in

11235-558: Was renamed the Postal Transportation Service on October 1, 1948, and existed until 1960. After 1960, the management of railway post office routes as well as Highway Post Office routes, Air Mail Facility , terminal railway post offices , and transfer offices , were shifted to the Bureau of Transportation . At their height, RPO cars were used on over 9,000 train routes covering more than 200,000 route miles in North America. While

11342-762: Was tested on the Edinburgh and Glasgow Railway in September of the following year, but the limited power from batteries prevented its general use. It was destroyed by railway workers, who saw it as a threat to their job security. By the middle of the nineteenth century most european countries had military uses for railways. Werner von Siemens demonstrated an electric railway in 1879 in Berlin. The world's first electric tram line, Gross-Lichterfelde Tramway , opened in Lichterfelde near Berlin , Germany, in 1881. It

11449-580: Was the first tram line in the world in regular service powered from an overhead line. Five years later, in the U.S. electric trolleys were pioneered in 1888 on the Richmond Union Passenger Railway , using equipment designed by Frank J. Sprague . The first use of electrification on a main line was on a four-mile section of the Baltimore Belt Line of the Baltimore and Ohio Railroad (B&O) in 1895 connecting
