A locomotive is a rail transport vehicle that provides the motive power for a train. If a locomotive is capable of carrying a payload, it is usually rather referred to as a multiple unit, motor coach, railcar or power car; the use of these self-propelled vehicles is increasingly common for passenger trains, but rare for freight trains.
Rail transport 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.
A tram is a type of urban rail transit consisting of either individual railcars or self-propelled multiple unit trains that run on tramway tracks on urban public streets; some include segments on segregated right-of-way. The tramlines or tram networks operated as public transport are called tramways or simply trams/streetcars. Because of their close similarities, trams are commonly included in the wider term light rail, which also includes systems separated from other traffic.
An overhead line or overhead wire is an electrical cable that is used to transmit electrical energy to electric locomotives, electric multiple units, trolleybuses or trams. The generic term used by the International Union of Railways for the technology is overhead line. It is known variously as overhead catenary, overhead contact line (OCL), overhead contact system (OCS), overhead equipment (OHE), overhead line equipment, overhead lines (OHL), overhead wiring (OHW), traction wire, and trolley wire.
The history of rail transport began before the beginning of the common era. It can be divided into several discrete periods defined by the principal means of track material and motive power used.
A third rail, also known as a live rail, electric rail or conductor rail, is a method of providing electric power to a railway locomotive or train, through a semi-continuous rigid conductor placed alongside or between the rails of a railway track. It is used typically in a mass transit or rapid transit system, which has alignments in its own corridors, fully or almost fully segregated from the outside environment. Third-rail systems are usually supplied from direct current electricity.
Railway electrification is the use of electric power for the propulsion of rail transport. Electric railways use either electric locomotives, electric multiple units or both. Electricity is typically generated in large and relatively efficient generating stations, transmitted to the railway network and distributed to the trains. Some electric railways have their own dedicated generating stations and transmission lines, but most purchase power from an electric utility. The railway usually provides its own distribution lines, switches, and transformers.
Melbourne tram route 109 is operated by Yarra Trams on the Melbourne tram network from Box Hill to Port Melbourne. The 19.3 kilometre route is operated out of Kew depot with A and C class trams.
Sestroretsk is a municipal town in Kurortny District of the federal city of St. Petersburg, Russia, located on the shores of the Gulf of Finland, the Sestra River and the Sestroretskiy Lake 34 kilometers (21 mi) northwest of St. Petersburg. Population: 37,248 (2010 Census); 40,287 (2002 Census); 35,498 (1989 Soviet census); 30,500 (1975).
Trams in Saint Petersburg are a major mode of public transit in the city of Saint Petersburg, Russia. Saint Petersburg once had the second-largest tram network in the world, consisting of about 340 kilometres (210 mi) of unduplicated track in the late 1980s. However, since 1995 the tramway network has declined sharply in size as major portions of track were removed, particularly in the city centre. Saint Petersburg lost its record to Melbourne, Australia. While it still had 285 kilometres (177 mi) of length in 2002, by early 2007 the tram network's had declined to just over 220 kilometres (140 mi), and by the 2010s operated on just 205.5 kilometres (127.7 mi) of network.
Fyodor Apollonovich Pirotsky, or Fedir Apollonovych Pirotskyy was a Russian engineer of Rusian ancestry, inventor of the world's first railway electrification system and electric tram While the commercialization of his inventions in the Russian Empire was relatively slow, Pirotsky is known to have met with Carl Heinrich von Siemens and influenced Siemens' eventual introduction of the first regular electric tram line.
The history of trams, streetcars, or trolleys began in the early nineteenth century. It can be divided up into several discrete periods defined by the principal means of motive power used.
The stud contact system is an obsolete ground-level power supply system for electric trams. Power supply studs were set in the road at intervals and connected to a buried electric cable by switches operated by magnets on the tramcars. Current was collected from the studs by a "skate" or "ski collector" under the tramcar. The system was popular for a while in the early 1900s but soon fell out of favour because of the unreliability of the magnetic switches, largely due to friction and rapid corrosion affecting its cast iron moving components.
A current collector is a device used in trolleybuses, trams, electric locomotives and EMUs to carry electric power (current) from overhead lines, electric third rails, or ground-level power supplies to the electrical equipment of the vehicles. Those for overhead wires are roof-mounted devices, those for rails are mounted on the bogies.
Sestroretsk railway station was a railway station in Sestroretsk, Russia handling transportation to northern destinations including Beloostrov and Sestroretsk.
The Weston-super-Mare Tramways were the electric street tramways of the seaside resort of Weston-super-Mare in Somerset, England. It operated a fleet of up to 16 standard gauge single- and double-deck tramcars on routes totalling 2.92 miles (4.70 km) to Birnbeck Pier, The Sanatorium and Locking Road. It opened in 1902 and was replaced by bus services in 1937.
Torquay Tramways operated electric street trams in Torquay, Devon, England, from 1907. They were initially powered by the unusual Dolter stud-contact electrification, but in 1911 was converted to more conventional overhead-line supply. The line was extended into neighbouring Paignton in 1911 but the whole network was closed in 1934.
The Bessbrook and Newry Tramway operated a 3 ft narrow gauge, hydro-electrically powered tramway transporting passengers and freight between Bessbrook and Newry in Northern Ireland between 1885 and 1948.
