89-626: An airport rail link is a service providing passenger rail transport between an airport and a nearby city. Direct links operate straight from the airport terminal to the city, while other links require an intermediate use of a people mover or shuttle bus . Advantages for the passenger include faster travel times and easy connections with other public transport. Advantages for the airport include increased patronage and enhanced accessibility for staff. Additionally, authorities have benefitted from less highway congestion, less pollution, and more business opportunities. Although airport rail links have been

178-486: A baggage claim or reclaim area is an area where arriving passengers claim checked-in baggage after disembarking from an airline flight. At most airports and many train stations, baggage is delivered to the passenger on a baggage carousel . Left luggage, also luggage storage or bag storage, is a place where one can temporarily store one's luggage so as to not have to carry it. Left luggage is not synonymous with lost luggage . Often at an airport or train station there may be

267-408: 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 ,

356-586: 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,

445-731: 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

534-542: 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

623-492: 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

712-431: 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

801-469: 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

890-567: A "macho thing" where "men would not accept suitcases with wheels". Others attribute the late invention to "the abundance of luggage porters with carts in the 1960s, the ease of curbside drop-offs at much smaller airports and the heavy iron casters then available." Passengers are allowed to carry a limited number of smaller bags with them in the vehicle, these are known as hand luggage (more commonly referred to as carry-on in North America ), and contain valuables and items needed during

979-550: 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

1068-409: A direct connection must use a people mover to access their terminal. People movers typically also serve parking lots, airport hotels and off-site car rental facilities. People movers are seen to have a higher perceived quality compared to a shuttle bus. Another hybrid solution is a direct link to an airport railway station connected to a shuttle bus. The passenger transfers from the railway station to

1157-478: 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

1246-437: 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

1335-498: 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

1424-423: 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

1513-477: 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

1602-676: 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

1691-465: 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

1780-555: A popular solution in Europe and Japan for decades, only recently have links been constructed in North America, South America, Africa, Oceania, and the rest of Asia. Some early examples of inter-city railway stations built to serve an airport include: The first rapid transit station to connect with an airport was Berlin's U-Bahn U6 Paradestraße station which opened in 1927 as Flughafen ( lit.   ' airport ' ) and

1869-439: 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

1958-474: A short shuttle bus transfer from the station to the airport terminal, whilst Cleveland's link is considered the first direct service in the Western Hemisphere. Tokyo Monorail , which opened in 1964 as Japan's first airport rail link, had its original southern terminus underneath the old domestic terminal of Haneda Airport . When Haneda Airport was expanded onto landfill reclaimed from Tokyo Bay in

2047-739: 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

2136-546: A staffed 'left luggage counter' or simply a coin-operated or automated locker system. While threats of terrorism all around the globe have caused this type of public storage to decrease over the past few decades, the sharing economy is causing a revival of the industry. Driven in part by the rapid growth of Airbnb and homestay traveling in general, a number of services offering short-term luggage storage by utilizing unused space at local businesses such as hotels, restaurants and retail shops have emerged. Baggage can also refer to

2225-407: 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

2314-632: 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

2403-408: 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

2492-498: A wheeled trunk in 1887, and a wheeled suitcase in 1945 – but these were not successfully commercialized. The first rolling suitcase was invented by a French engineer, Maurice Partiot, who was living in the USA at that time. The patent was registered n° 2 463 713, March 8, 1949. But the application was not pursued by its inventor and the patent lapsed in 1967. Bernard D. Sadow developed the first commercial rolling suitcase by applying for

2581-531: 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

2670-410: 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

2759-545: Is baggage that has a built-in or a removable battery within. It often includes features designed to help with travel, including GPS tracking and USB ports to charge electronics. Some bags include a WiFi hotspot and electric wheels for personal transportation. Several smart luggage companies have shut down as a result of a ban which came into effect in January 2018 on smart luggage with non-removable batteries being carried as check-in luggage on flights. In airport terminals,

2848-399: 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

2937-506: Is often used where the airport is outside the urban area and some way from the mass transit system but a direct downtown service is required. There are various ways this can be achieved: it may operate on a combination of existing or newly built mainline rail track using a dedicated fleet of rolling stock designed for airport service. Similarly to high-speed and inter-city services, these services often have premium fares, lower frequencies and luxury features. For airports built within or close to

3026-601: Is to provide high-capacity service. A hybrid solution adopted in some cities is a direct link to an airport railway station connected to a people mover . The passenger transfers from the railway station to the people mover which then completes the journey to the airport terminal. While this option is commonly chosen to reduce construction costs, it is only feasible when a rail line is near the airport. Some airports, such as San Francisco International Airport , are directly served by an airport rail link to some terminals but not others. In such cases, passengers using terminals that lack

3115-408: 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

3204-556: 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

3293-759: The Narita Express between Narita International Airport and Tokyo , the Union Pearson Express between Toronto Pearson International Airport and Toronto , and the Leonardo Express between Leonardo da Vinci–Rome Fiumicino Airport and Rome . Examples include the East–West Line between Changi Airport station and Singapore, the Silver Line between Washington Dulles International Airport station and Washington, D.C., and

3382-762: The Orange Line between DFW Airport Terminal A station and Dallas. Examples include Soekarno–Hatta International Airport via Soekarno–Hatta Airport Skytrain to/from SHIA station, London Luton Airport via Luton DART to/from Luton Airport Parkway station, and Paris Orly Airport via Orlyval to/from Antony station. Examples include Shijiazhuang Zhengding International Airport via shuttle bus to/from Zhengding Airport station, Salvador Bahia Airport via shuttle bus to/from Aeroporto station, and Milwaukee Mitchell International Airport via shuttle bus to/from Milwaukee Airport station. Rail transport Rail transport (also known as train transport )

3471-692: 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

3560-615: 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

3649-414: 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

3738-458: 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

3827-418: 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

3916-487: 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

4005-521: 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

4094-508: 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),

4183-659: The 1980s–2010s, the monorail was extended to the new terminals as well, with the original southern terminus later renamed as Tenkūbashi Station . A high-speed or inter-city service provides direct travel between an airport and its surrounding cities. This solution usually requires the building of new track, whether it is a newly built main line or a branch (spur) line . These services often have premium fares, lower frequencies (e.g. every 30 minutes) and luxury features (e.g. luggage racks, power outlets, Wi-Fi, bathrooms). Integration with high-speed and inter-city services has produced alliances where airlines sell tickets that include

4272-432: The 2004 version of their signature Silhouette line. These are otherwise similar in design to two-wheel roll-aboards, with a vertical orientation and a retracting handle, but are designed to be pushed beside or in front of the traveler, rather than pulled behind them. These are often referred to as "spinner" luggage, since they can spin about their vertical axis . Sadow attributes the late invention of luggage on wheels to

4361-464: 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

4450-530: 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

4539-514: 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

4628-506: The Travelpro company, which marketing the suitcases under the trademark "Rollaboard". The terms rollaboard and roll-aboard are used generically, however. While initially designed for carry-on use (to navigate through a large terminal), as implied by the analogous name, similar designs are also used for checked baggage . More recently, four-wheeled luggage with casters has become popular, notably since their use by Samsonite in

4717-551: The city limits, extending rapid transit or light rail to the airport allows seamless transport to suburbs and full integration with other lines. These services usually have a higher frequency (e.g. every 5 minutes) but longer travel times due to the service making many intermediate stops between the airport and the city centre. Additionally, there may not be enough space for baggage commonly carried by airport-bound passengers. Luggage stowing facilities are not commonly found on rapid transit or light rail vehicles as their primary objective

4806-427: The connecting rail service. Parts of Europe have seen integration of high-speed rail stations into airports, with domestic and international TGV services from Paris Charles de Gaulle Airport and ICE services from Frankfurt Airport . Because of this, some stations have received IATA codes . A regional or commuter "airport express" service provides direct travel between an airport and its city centre. This solution

4895-430: 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

4984-402: 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

5073-471: 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

5162-527: 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

5251-475: 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

5340-522: 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

5429-428: The following decades, as reflected in patents such as a 1948 US patent by Herbert Ernest Mingo, for a "device for the handling of trunks, suitcases, and the like". A US patent for a "luggage carriage" filed in 1949 (and published 1953), and another for a "luggage carriage harness", were both made by Kent R. Costikyan. However, the wheels were external to the suitcases. Patents had been published for wheeled luggage –

5518-435: The highest possible radius. All these features are dramatically different from freight operations, thus justifying exclusive high-speed rail lines if it is economically feasible. Baggage Baggage (not luggage), or baggage train , can also refer to the train of people and goods, both military and of a personal nature, which commonly followed pre-modern armies on campaign. Luggage has changed over time. Historically

5607-420: The invention. Sadow's four-wheeled suitcases, pulled using a loose strap, were later surpassed in popularity by suitcases that feature two wheels and are pulled in an upright position using a long handle. These were invented in 1987 by US pilot Robert Plath, and initially sold to crew members. Plath later commercialized them, after travelers became interested after seeing them in use by crew members, and founded

5696-408: The journey. There is normally storage space provided for hand luggage, either under seating, or in overhead lockers. Trains often have luggage racks at the ends of the carriage near the doors, or above the seats if there are compartments. On aircraft, the size and weight of hand luggage is regulated, along with the number of bags. Some airlines charge for carry-on over a certain number. Smart luggage

5785-1230: 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

5874-429: 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

5963-569: 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

6052-433: 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

6141-692: The most common types of luggage were chests or trunks made of wood or other heavy materials. These would be shipped by professional movers. Since the Second World War smaller and more lightweight suitcases and bags that can be carried by an individual have become the main form of luggage. According to the Oxford English Dictionary , the word baggage comes from the Old French bagage (from baguer 'tie up') or from bagues 'bundles'. It may also be related to

6230-412: 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

6319-525: 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

6408-414: The rolling luggage patent, which was officially known as; United States patent 3,653,474 for “Rolling Luggage”, in 1970. Two years later in 1972 Bernard D. Sadow was given the wheeled suitcases patent, which became successful. The patent application cited the increase in air travel, and "baggage handling [having] become perhaps the single biggest difficulty encountered by an air passenger", as background of

6497-562: The shuttle bus which then completes the journey to the airport terminal. A shuttle bus requires no specialised infrastructure, and is often the preferred choice at smaller or low-cost airports. Shuttle buses may involve a wait for a transfer to the next stage of the journey and often suffer from lower perceived quality and market share compared to direct connections. Examples include Schipol Airport station to other Dutch cities, Zürich Flughafen station to other Swiss cities, and Daxing Airport station to other Chinese cities. Examples include

6586-441: 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

6675-475: 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

6764-543: 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

6853-471: 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

6942-629: 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 ,

7031-607: The word bag . Also according to the Oxford English Dictionary, the word luggage originally meant inconveniently heavy baggage and comes from the verb lug and the suffix -age . Luggage carriers – light-weight wheeled carts on which luggage could be temporarily placed or that can be temporarily attached to luggage – date at least to the 1930s, such as in US patent 2,132,316 "Luggage carrier" by Anne W. Newton (filed 1937, published 1938). These were refined over

7120-622: 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

7209-512: 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

7298-602: 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

7387-514: 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

7476-706: 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

7565-656: Was built to provide direct access to Berlin Tempelhof Airport . However, the connection was removed in 1937 and the preceding Platz der Luftbrücke station was instead granted the connection and remained so until Berlin Tempelhof Airport's closure in 2008. Other early examples of rapid transit stations connecting with airports include Boston's MBTA Blue Line Airport station which opened in 1952 (rebuilt in 2004), and Cleveland's RTA Rapid Transit Red Line Cleveland Hopkins International Airport station which opened in 1968 (rebuilt in 1994). Boston's link requires

7654-548: 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 ,

7743-489: 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

7832-762: 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

7921-636: 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
