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,
432-731: 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
540-542: 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
648-454: A guideway . This is an uncommon mode of transportation (excluding elevators ) due to the complexity of automation. A fully implemented system might provide most of the convenience of individual automobiles with the efficiency of public transit. The crucial innovation is that the automated vehicles carry just a few passengers, turn off the guideway to pick up passengers (permitting other PRT vehicles to continue at full speed), and drop them off to
756-442: 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
864-528: 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
972-431: 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
1080-469: 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
1188-543: A body of water. A foot-passenger ferry with many stops is sometimes called a water bus . Ferries form a part of the public transport systems of many waterside cities and islands, allowing direct transit between points at a capital cost much lower than bridges or tunnels, though at a lower speed. Ship connections of much larger distances (such as over long distances in water bodies like the Mediterranean Sea ) may also be called ferry services. A report published by

A number of sources attribute this trend to the rise in popularity of remote work, ride-sharing services, and car loans being relatively cheap across many countries. Major cities such as Toronto, Paris, Chicago, and London have seen this decline and have attempted to intervene by cutting fares and encouraging new modes of transportation, such as e-scooters and e-bikes. Because of

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
1512-478: 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
1620-552: A few stops per city. These services may also be international. High-speed rail is passenger trains operating significantly faster than conventional rail—typically defined as at least 200 kilometres per hour (120 mph). The most predominant systems have been built in Europe and East Asia, and compared with air travel, offer long-distance rail journeys as quick as air services, have lower prices to compete more effectively and use electricity instead of combustion. Urban rail transit
1728-437: 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
1836-498: 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
1944-423: 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
2052-477: 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

#17327823979812376-676: A railway with freight trains . A rapid transit railway system (also called a metro, underground, heavy rail, or subway) operates in an urban area with high capacity and frequency, and grade separation from other traffic. Heavy rail is a high-capacity form of rail transit, with 4 to 10 units forming a train, and can be the most expensive form of transit to build. Modern heavy rail systems are mostly driverless, which allows for higher frequencies and less maintenance cost. Systems are able to transport large numbers of people quickly over short distances with little land use. Variations of rapid transit include people movers , small-scale light metro and
2484-401: A remnant of the original Broadway Line , ending at 8th Street . Service was terminated in 1913.

2592-439: 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
2700-502: A schedule, operated on established routes, and that may charge a posted fee for each trip. There is no rigid definition of which kinds of transport are included, and air travel is often not thought of when discussing public transport—dictionaries use wording like "buses, trains, etc." Examples of public transport include city buses , trolleybuses , trams (or light rail ) and passenger trains , rapid transit (metro/subway/underground, etc.) and ferries . Public transport between cities
2808-480: A set of trolley poles for mobility. Online Electric Vehicles are buses that run on a conventional battery, but are recharged frequently at certain points via underground wires. Certain types of buses, styled after old-style streetcars, are also called trackless trolleys, but are built on the same platforms as a typical diesel , CNG , or hybrid bus; these are more often used for tourist rides than commuting and tend to be privately owned. Passenger rail transport
2916-412: A single (or return) trip, or valid within a certain area for a period of time (see transit pass ). The fare is based on the travel class, either depending on the traveled distance, or based on zone pricing . The tickets may have to be shown or checked automatically at the station platform or when boarding, or during the ride by a conductor . Operators may choose to control all riders, allowing sale of
3024-739: 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
3132-413: A smaller suburban or town center. The stations are often combined with shuttle bus or park and ride systems. Frequency may be up to several times per hour, and commuter rail systems may either be part of the national railway or operated by local transit agencies. Common forms of commuter rail employ either diesel electric locomotives, or electric multiple unit trains. Some commuter train lines share
3240-407: 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

3456-632: 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
3564-431: A tram line. Light rail lines are, thus, essentially modernized interurbans . Unlike trams, light rail trains are often longer and have one to four cars per train. Somewhere between light and heavy rail in terms of carbon footprint , monorail systems usually use overhead single tracks, either mounted directly on the track supports or put in an overhead design with the train suspended. Monorail systems are used throughout
3672-408: 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

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
3888-507: Is a term used for buses operating on dedicated right-of-way, much like a light rail. Coach services use coaches (long-distance buses) for suburb-to-CBD or longer-distance transportation. The vehicles are normally equipped with more comfortable seating, a separate luggage compartment, video and possibly also a toilet. They have higher standards than city buses, but a limited stopping pattern. Trolleybuses are electrically powered buses that receive power from overhead power line by way of

Commuter rail is part of an urban area's public transport. It provides faster services to outer suburbs and neighboring satellite cities . Trains stop at train stations that are located to serve
4212-484: Is common with roads for automobiles. Interchanges are locations where passengers can switch from one public transport route to another. This may be between vehicles of the same mode (like a bus interchange), or e.g. between bus and train. It can be between local and intercity transport (such as at a central station or airport). Timetables (or 'schedules' in North American English ) are provided by

Most public transport systems run along fixed routes with set embarkation/disembarkation points to a prearranged timetable, with the most frequent services running to a headway (e.g.: "every 15 minutes" as opposed to being scheduled for any specific time of the day). However, most public transport trips include other modes of travel, such as passengers walking or catching bus services to access train stations. Share taxis offer on-demand services in many parts of

4536-430: Is especially valuable in cases where there are capacity problems for private transport. Investments in infrastructure are expensive and make up a substantial part of the total costs in systems that are new or expanding. Once built, the infrastructure will require operating and maintenance costs, adding to the total cost of public transport. Sometimes governments subsidize infrastructure by providing it free of charge, just as
4644-656: Is reasonably comfortable (seats, toilets, services), and can thus be scheduled and used pleasurably, productively or for (overnight) rest. Chauffeured movement is enjoyed by many people when it is relaxing, safe, but not too monotonous. Waiting, interchanging, stops and holdups, for example due to traffic or for security, are discomforting. Jet lag is a human constraint discouraging frequent rapid long-distance east–west commuting, favoring modern telecommunications and VR technologies. An airline provides scheduled service with aircraft between airports. Air travel has high speeds, but incurs large waiting times before and after travel, and
4752-444: Is the conveyance of passengers by means of wheeled vehicles specially designed to run on railways. Trains allow high capacity at most distance scales, but require track , signalling , infrastructure and stations to be built and maintained resulting in high upfront costs. Intercity rail is long-haul passenger services that connect multiple urban areas. They have few stops, and aim at high average speeds, typically only making one of
4860-721: Is therefore often only feasible over longer distances or in areas where a lack of surface infrastructure makes other modes of transport impossible. Bush airlines work more similarly to bus stops; an aircraft waits for passengers and takes off when the aircraft is full. Bus services use buses on conventional roads to carry numerous passengers on shorter journeys. Buses operate with low capacity (compared with trams or trains), and can operate on conventional roads, with relatively inexpensive bus stops to serve passengers. Therefore, buses are commonly used in smaller cities, towns, and rural areas, and for shuttle services supplementing other means of transit in large cities. Bus rapid transit (BRT)
4968-408: 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

By 1907, the line to the Christopher Street Ferry was gone, and the 14th Street-Williamsburg Bridge Line used the 14th Street trackage west of Union Square . Instead, 17th and 18th Streets cars continued south from Union Square on University Place on

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

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

The canal itself as a form of infrastructure dates back to antiquity. In ancient Egypt canals were used for freight transportation to bypass the Aswan cataract. The Chinese also built canals for water transportation as far back as
5940-851: The warring States period which began in the 5th century BCE. Whether or not those canals were used for for-hire public transport remains unknown; the Grand Canal in China (begun in 486 BCE) served primarily the grain trade . The bus , the first organized public transit system within a city, appears to have originated in Paris in 1662, although the service in question, Carrosses à cinq sols (English: five-sol coaches), which have been developed by mathematician and philosopher Blaise Pascal , lasted only fifteen years until 1677. Buses are known to have operated in Nantes in 1826. The public bus transport system

Twenty-five cities have systems under construction. People movers are a special term for grade-separated rail which uses vehicles that are smaller and shorter in size. These systems are generally used only in a small area such as a theme park or an airport. Trams (also known as streetcars or trolleys) are railborne vehicles that originally ran in city streets, though over decades more and more dedicated tracks are used. They have higher capacity than buses, but must follow dedicated infrastructure with rails and wires either above or below
7020-447: The day or part of the day (known as clock-face scheduling ). Often, more frequent services or even extra routes are operated during the morning and evening rush hours . Coordination between services at interchange points is important to reduce the total travel time for passengers. This can be done by coordinating shuttle services with main routes, or by creating a fixed time (for instance twice per hour) when all bus and rail routes meet at

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

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
7560-475: 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
7668-522: 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
7776-1230: 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
7884-456: The location of their choice (rather than at a stop). Conventional transit simulations show that PRT might attract many auto users in problematic medium-density urban areas. A number of experimental systems are in progress. One might compare personal rapid transit to the more labor-intensive taxi or paratransit modes of transportation, or to the (by now automated) elevators common in many publicly accessible areas. Cable-propelled transit (CPT)
7992-429: 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
8100-400: The lost time and statistically higher risk of accident in private transport , together with the initial, running and parking costs. Loss of control , spatial constriction, overcrowding , high speeds/accelerations, height and other phobias may discourage use of public transport. Actual travel time on public transport becomes a lesser consideration when predictable and when travel itself
8208-569: 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
8316-433: 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
8424-412: 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
8532-525: 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
8640-492: The public transport leg of their journey and how close it leaves them to their desired destination. Timeliness is how long they must wait for the vehicle. Directness records how far a journey using public transport deviates from a passenger's ideal route. In selecting between competing modes of transport , many individuals are strongly motivated by direct cost (travel fare/ ticket price to them) and convenience , as well as being informed by habit . The same individual may accept
8748-481: The purchase of a ticket to generate revenue for the operators. Tickets may be bought either in advance, or at the time of the journey, or the carrier may allow both methods. Passengers may be issued with a paper ticket, a metal or plastic token , or a magnetic or electronic card ( smart card , contactless smart card ). Sometimes a ticket has to be validated, e.g. a paper ticket has to be stamped, or an electronic ticket has to be checked in. Tickets may be valid for
8856-619: The purposes of mass transit. Many, if not all, of these systems are implemented and fully integrated within existing public transportation networks. Examples include Metrocable (Medellín) , Metrocable (Caracas) , Mi Teleférico in La Paz , Portland Aerial Tram , Roosevelt Island Tramway in New York City, and the London Cable Car . A ferry is a boat used to carry (or ferry ) passengers, and sometimes their vehicles, across
8964-615: The reduced emissions and other environmental impacts of using public transportation over private transportation, many experts have pointed to an increased investment in public transit as an important climate change mitigation tactic. Conveyances designed for public hire are as old as the first ferry service . The earliest public transport was water transport . Ferries appear in Greek mythology writings. The mystical ferryman Charon had to be paid and would only then take passengers to Hades . Some historical forms of public transport include
9072-471: The smoke filled subway tunnels from the steam engines. In 1894, Boston built the first subway in the United States, an electric streetcar line in a 1.5-mile tunnel under Tremont Street's retail district. Other cities quickly followed, constructing thousands of miles of subway in the following decades. In March 2020, Luxembourg abolished fares for trains, trams and buses and became the first country in
9180-441: 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
9288-401: The ticket at the time of ride. Alternatively, a proof-of-payment system allows riders to enter the vehicles without showing the ticket, but riders may or may not be controlled by a ticket controller ; if the rider fails to show proof of payment, the operator may fine the rider at the magnitude of the fare. Passenger rail transport Rail transport (also known as train transport ) is
9396-475: 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
9504-504: The track, limiting their flexibility. In the United States, trams were commonly used prior to the 1930s, before being superseded by the bus. In modern public transport systems, they have been reintroduced in the form of the light rail. Light rail is a term coined in 1972 and uses mainly tram technology. Light rail has mostly dedicated right-of-ways and less sections shared with other traffic and usually step-free access. Light rails line are generally traversed with increased speed compared to
9612-543: 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
9720-471: 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
9828-517: The transport operator to allow users to plan their journeys. They are often supplemented by maps and fare schemes to help travelers coordinate their travel. Online public transport route planners help make planning easier. Mobile apps are available for multiple transit systems that provide timetables and other service information and, in some cases, allow ticket purchase, some allowing to plan your journey, with time fares zones e.g. Services are often arranged to operate at regular intervals throughout
9936-408: The use and extent of public transport. The International Association of Public Transport (UITP) is the international network for public transport authorities and operators, policy decision-makers, scientific institutes and the public transport supply and service industry. It has over 1,900 members from more than 100 countries from all over the globe. In recent years, some high-wealth cities have seen
10044-629: 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 ,
10152-536: The world (especially in Europe and east Asia , particularly Japan ), but apart from public transit installations in Las Vegas and Seattle, most North American monorails are either short shuttle services or privately owned services (With 150,000 daily riders, the Disney monorail systems used at their parks may be the most famous in the world). Personal rapid transit is an automated cab service that runs on rails or
10260-559: 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
10368-544: The world to make all public transport free. The Encyclopædia Britannica specifies that public transportation is within urban areas, but does not limit its discussion of the topic to urban areas. Seven criteria estimate the usability of different types of public transport and its overall appeal. The criteria are speed, comfort, safety, cost, proximity, timeliness and directness. Speed is calculated from total journey time including transfers. Proximity means how far passengers must walk or otherwise travel before they can begin
10476-745: The world, which may compete with fixed public transport lines, or complement them, by bringing passengers to interchanges. Paratransit is sometimes used in areas of low demand and for people who need a door-to-door service. Urban public transit differs distinctly among Asia, North America, and Europe. In Asia, profit-driven, privately owned and publicly traded mass transit and real estate conglomerates predominantly operate public transit systems. In North America, municipal transit authorities most commonly run mass transit operations. In Europe, both state-owned and private companies predominantly operate mass transit systems. For geographical, historical and economic reasons, differences exist internationally regarding
10584-512: 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
10692-965: Was abandoned in 1913. The Central Crosstown Railroad was chartered March 28, 1873, and opened within a few years. The original line began at the Christopher Street Ferry and ran north on West Street (west of the Central Park, North and East River trackage), northeast on 11th Street , north on 7th Avenue (along Broadway and Seventh Avenue Railroad trackage), east on 14th Street to Union Square , north on Broadway (also Broadway and Seventh Avenue Railroad trackage), east on 17th Street (eastbound) and 18th Street (westbound), north on 1st Avenue ( Central Park, North and East River Railroad trackage), and east on 23rd Street . Another line opened later, continuing west on 14th Street, including Bleecker Street and Fulton Ferry Railroad trackage west of 9th Avenue . The company leased
10800-602: 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
10908-514: 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
11016-787: Was built for 11 miles of track for the Union Passenger Railway in Tallahassee, Florida, in 1888. Electric streetcars could carry heavier passenger loads than predecessors, which reduced fares and stimulated greater transit use. Two years after the Richmond success, over thirty two thousand electric streetcars were operating in America. Electric streetcars also paved the way for the first subway system in America. Before electric streetcars, steam powered subways were considered. However, most people believed that riders would avoid
11124-706: 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
11232-548: 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 ,
11340-609: Was introduced to London in July 1829. The first passenger horse-drawn vehicle opened in 1806. It ran along the Swansea and Mumbles Railway . In 1825 George Stephenson built the Locomotion No 1 for the Stockton and Darlington Railway in northeast England, the first public steam railway in the world. The world's first steam-powered underground railway opened in London in 1863. The first successful electric streetcar
11448-489: 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
11556-762: 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
11664-636: 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
