The railway system in Great Britain is the oldest railway system in the world. The first locomotive-hauled public railway opened in 1825, which was followed by an era of rapid expansion. Most of the track is managed by Network Rail, which in 2017 had a network of 9,824 miles (15,811 km) of standard-gauge lines, of which 3,339 miles (5,374 km) were electrified. In addition, some cities have separate metro, light rail and tram systems, among them the historic London Underground and the Glasgow Subway. There are also many private railways, some of them narrow-gauge, which are primarily short lines for tourists. The main rail network is connected with that of continental Europe by the Channel Tunnel and High Speed 1, opened in 1994 and 2007 respectively.
Commuter rail or suburban rail is a passenger rail transport service that primarily operates within a metropolitan area, connecting commuters to a central city from adjacent suburbs or commuter towns. Commuter rail systems can use locomotive-hauled trains or multiple units, using electric or diesel propulsion. Distance charges or zone pricing may be used.
A diesel multiple unit or DMU is a multiple-unit train powered by on-board diesel engines. A DMU requires no separate locomotive, as the engines are incorporated into one or more of the carriages. Diesel-powered single-unit railcars are also generally classed as DMUs. Diesel-powered units may be further classified by their transmission type: diesel–mechanical DMMU, diesel–hydraulic DHMU, or diesel–electric DEMU.
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.
Light rail is a form of passenger urban rail transit that uses rolling stock derived from tram technology while also having some features from heavy rapid transit.
Inter-city rail services are express trains that run services that connect cities over longer distances than commuter or regional trains. They include rail services that are neither short-distance commuter rail trains within one city area nor slow regional rail trains stopping at all stations and covering local journeys only. An inter-city train is typically an express train with limited stops and comfortable carriages to serve long-distance travel.
A railway platform is an area in a train station alongside a railway track providing convenient access to trains. Almost all stations have some form of platform, with larger stations having multiple platforms.
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.
The InterCity 125 or High Speed Train (HST) is a diesel-powered high-speed passenger train built by British Rail Engineering Limited between 1975 and 1982. A total of 95 sets were produced, each comprising two Class 43 power cars, one at each end, and a rake of seven or eight Mark 3 coaches. The name is derived from its top operational speed of 125 mph (201 km/h). At times, the sets have been classified as British Rail Classes 253, 254 and 255.
Maglev is a system of rail transport whose rolling stock is levitated by electromagnets rather than rolled on wheels, eliminating rolling resistance.
The InterCity 225 is an electric push-pull high speed train in the United Kingdom, comprising a Class 91 electric locomotive, nine Mark 4 coaches and a Driving Van Trailer (DVT). The Class 91 locomotives were built by British Rail Engineering Limited's Crewe Works as a spin-off from the Advanced Passenger Train project, which was abandoned during the 1980s, whilst the coaches and DVT were constructed by Metro-Cammell in Birmingham and Breda in Italy, again borrowing heavily from the Advanced Passenger Train. The trains were designed to operate at up to 140 mph (225 km/h) in regular service, but are limited to 125 mph (200 km/h) principally due to a lack of cab signalling and the limitations of the current overhead line equipment. They were introduced into service between 1989 and 1991 for intercity services on the East Coast Main Line (ECML) from London King's Cross to Leeds, York and Edinburgh.
Various terms are used for passenger railway lines and equipment; the usage of these terms differs substantially between areas:
The British Rail Class 43 (HST) is the TOPS classification used for the InterCity 125 High Speed Train diesel-electric power cars, built by British Rail Engineering Limited from 1975 to 1982, and in service in the UK since 1976.
Rail freight transport is the use of railways and trains to transport cargo as opposed to human passengers.
Turkish State Railways (TCDD) started building high-speed rail lines in 2003. TCDD has branded its high-speed service as Yüksek Hızlı Tren (YHT) which currently operates on three lines: the Ankara–Istanbul high-speed railway, the Ankara–Konya high-speed railway and the Ankara-Sivas high-speed railway. YHT is the only high-speed rail service in Turkey, with two types of EMU train models operating at speeds of up to 250 km/h (155 mph) (HT65000) or 300 km/h (186 mph) (HT80000).
High-speed rail in the United Kingdom is provided on five upgraded railway lines running at top speeds of 125 mph (200 km/h) and one purpose-built high-speed line reaching 186 mph (300 km/h).
CrossCountry is a British train operating company owned by Arriva UK Trains, operating the current CrossCountry franchise.
A passenger train is a train used to transport people along a railroad line, as opposed to a freight train that carries goods. These trains may consist of unpowered passenger railroad cars hauled by one or more locomotives, or may be self-propelled; self propelled passenger trains are known as multiple units or railcars. Passenger trains stop at stations or depots, where passengers may board and disembark. In most cases, passenger trains operate on a fixed schedule and have priority over freight trains.
Rapid transit or mass rapid transit (MRT) or heavy rail, commonly referred to as metro, is a type of high-capacity public transport that is generally built in urban areas. A grade separated rapid transit line below ground surface through a tunnel can be regionally called a subway, tube, metro or underground. They are sometimes grade-separated on elevated railways, in which case some are referred to as el trains – short for "elevated" – or skytrains. Rapid transit systems are railways, usually electric, that unlike buses or trams operate on an exclusive right-of-way, which cannot be accessed by pedestrians or other vehicles.
Elfric Wells Chalmers Kearney was an Australian inventor, engineer and author. Born in Geelong, Victoria in 1881, he spent most of his life in the United Kingdom. He was educated briefly at Ellesmere College, Shropshire during 1894 but left in October on account of ill health.
