Top And Tail
A top-and-tail railway train has locomotives at both ends, for ease of changing direction, especially where the terminal station has no run-round loop. This is a British term. It is normal for only the leading locomotive to power the train when in top-and-tail mode. It is properly distinct from a push–pull train, which has a locomotive at one end and a control cab at the other end. Trains going up zig zags of the Khyber Pass are top-and-tailed, although Pakistan Railways calls this by a different term. In Japan, the term "push-pull" is confusingly used to describe trains top-and-tailed with a locomotive at either end. (True push-pull operation with a locomotive at one end is not seen on Japanese mainline railways.) Australia In New South Wales the XPT is a train with a light weight locomotive at either end. It is based on the British HST. The locomotive at the front operates at full traction power, while the locomotive at the rear operates at half power, the other half ...

Railway
Rail transport (also known as train transport) is a means of transport using wheeled vehicles running in railway track, tracks, which usually consist of two parallel steel railway track, 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 rail freight transport, freight transport globally, thanks to its Energy efficiency in transport, energy efficiency and potentially high-speed rail, high speed.Rolling stock on rails generally encounters lower friction, frictional resistance than rubber-tyred road vehicles, allowing rail cars to be coupled into longer trains. Power is usually provided by Diesel locomotive, diesel or Electric locomotive, electric locomotives. While railway transport is capital intensity, 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 an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Train
A train (from Old French , from Latin">-4; we might wonder whether there's a point at which it's appropriate to talk of the beginnings of French, that is, when it wa ... , from Latin , "to pull, to draw") is a series of connected vehicles that run along a railway track and Passenger train, transport people or Rail freight transport, freight. Trains are typically pulled or pushed by locomotives (often known simply as "engines"), though some are self-propelled, such as multiple units or railcars. Passengers and cargo are carried in railroad cars, also known as wagons or carriages. Trains are designed to a certain gauge, or distance between rails. Most trains operate on steel tracks with steel wheels, the low friction of which makes them more efficient than other forms of transport. Many countries use rail transport. Trains have their roots in wagonways, which used railway tracks and were powered by horses or pulled by cables. Following the invention of the steam locomo ...

Locomotive
A locomotive is a rail transport, rail vehicle that provides the motive power for a train. Traditionally, locomotives pulled trains from the front. However, Push–pull train, push–pull operation has become common, and in the pursuit for longer and heavier freight trains, companies are increasingly using distributed power: single or multiple locomotives placed at the front and rear and at intermediate points throughout the train under the control of the leading locomotive. Etymology The word ''locomotive'' originates from the Latin language, Latin 'from a place', Ablative case, ablative of 'place', and the Medieval Latin 'causing motion', and is a shortened form of the term ''locomotive engine'', which was first used in 1814 to distinguish between self-propelled and stationary steam engines. Classifications Prior to locomotives, the motive force for railways had been generated by various lower-technology methods such as human power, horse power, Gravity railroad, g ...

Run-round Loop
A headshunt (or escape track in the United States) is a short length of track provided to release locomotives at terminal platforms, or to allow shunting to take place clear of main lines. Terminal headshunt A 'terminal headshunt' is a short length of track that allows a locomotive to uncouple from its train, move forward, and then run back past it on a parallel track. Such headshunts are typically installed at a terminal station to allow the locomotive of an arriving train to move to the opposite end of (in railway parlance, 'run around') its train so that it can then haul the same train out of the station in the other direction (assuming, of course, that it is a locomotive equipped to run in either direction; for locomotives that only operate in one direction, a wye or turntable needs to be provided to physically turn the engine around, as well as a run-around track). Reversing headshunt Found primarily on metro systems, rapid transit light rail networks, and tramways, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Push–pull Train
Push–pull is a configuration for locomotive-hauled trains, allowing them to be driven from either end of the train, whether having a locomotive at each end or not. A push–pull train has a locomotive at one end of the train, connected via some form of remote control, such as multiple-unit train control, to a vehicle equipped with a control cab at the other end of the train. This second vehicle may be another locomotive, or an unpowered control car. In the UK and some other parts of Europe, the control car is referred to as a ''driving trailer'' (or driving van trailer/DVT where there is no passenger accommodation); in the US and Canada, they are called ''cab cars'' and in Australia, they are called driving trailers. Train formation Locomotive at one end Historically, push–pull trains with steam power provided the driver with basic controls at the cab end along with a bell or other signalling code system to communicate with the fireman located in the engine itse ...

Zig Zag (railway)
A railway zig zag or switchback is a railway operation in which a train is required to switch its direction of travel in order to continue its journey. While this may be required purely from an operations standpoint, it is also ideal for climbing steep gradients with minimal need for tunnels and heavy earthworks. For a short distance (corresponding to the middle leg of the letter "Z"), the direction of travel is reversed, before the original direction is resumed. Some switchbacks do not come in pairs, and the train may then need to travel backwards for a considerable distance. A location on railways constructed by using a zig-zag alignment at which trains must reverse direction to continue is a reversing station. One of the best examples is the Darjeeling Himalayan Railway, a UNESCO World Heritage Site railway in India, which has six full zig zags and three Spiral (railway), spirals. Advantages Zig zags tend to be cheaper to construct because the grades required are di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Khyber Pass
The Khyber Pass (Urdu: درۂ خیبر; ) is a mountain pass in the Khyber Pakhtunkhwa province of Pakistan, on the border with the Nangarhar Province of Afghanistan. It connects the town of Landi Kotal to the Valley of Peshawar at Jamrud by traversing part of the White Mountains, Afghanistan, White Mountains. Since it was part of the ancient Silk Road, it has been a vital trade route between Central Asia and the Indian subcontinent and a Military strategy, strategic military choke point for various states that controlled it. The Khyber Pass is considered one of the most famous mountain passes in the world. Geography Following Asian Highway 1 (AH1), the summit of the pass at the town of Landi Kotal is inside Pakistan, descending into the Valley of Peshawar at Jamrud, about from the Afghan border by traversing part of the Spin Ghar mountains.

New South Wales XPT
The New South Wales XPT (short for eXpress Passenger Train) is a class of diesel locomotive, diesel-powered passenger trains built by Commonwealth Engineering, Comeng and ABB. Based on the British Rail-designed InterCity 125, High Speed Train, each XPT set comprises two XP power cars in a push–pull train, push-pull configuration and, between them, from four to seven passenger carriages. The XPT was procured following a competitive invitation to tender, tendering process, with an initial contract for 30 trainsets, comprising 10 power cars and 20 carriages, in March 1980. The design of the InterCity 125 was substantially modified. Testing commenced in August 1981 and the first set entered service under the State Rail Authority during January 1982. The XPT proved to be considerably faster than existing trains, reducing the journey time between Sydney and Melbourne by up to two hours. Throughout the 1980s, additional XPT sets were procured, permitting the launch of services such ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
InterCity 125
The InterCity 125 (originally Inter-City 125) or High Speed Train (HST) is a diesel-powered High-speed rail, high-speed passenger train built by British Rail Engineering Limited between 1975 and 1982. A total of 95 sets were produced, each comprising two British Rail Class 43 (HST), Class 43 power cars, one at each end, and a rake (train)#R, rake of seven or eight British Rail Mark 3, Mark 3 coaches. The name is derived from its top operational speed of . At times, the sets have been classified as British Rail Classes 253, 254 and 255. British Rail (BR) initially developed the HST as an interim measure in the early 1970s, as delays and cost concerns began to threaten their primary high-speed train project, the Advanced Passenger Train (APT). The HSTs are now widely considered to be among the most successful trains to have operated on the British railway network, both in terms of their initial impact and their longevity: their introduction into service between 1976 and 1982 res ...
