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 ha ...

Railway
Rail transport (also known as train transport) is a means of transport that transfers passengers and goods on wheeled vehicles running on rails, which are incorporated in Track (rail transport), tracks. In contrast to road transport, where the vehicles run on a prepared flat surface, rail vehicles (rolling stock) are directionally guided by the tracks on which they run. Tracks usually consist of steel rails, installed on Railroad tie, sleepers (ties) set in track ballast, ballast, on which the rolling stock, usually fitted with metal wheels, moves. Other variations are also possible, such as "slab track", in which the rails are fastened to a concrete foundation resting on a prepared subsurface. Rolling stock in a rail transport system generally encounters lower friction, frictional resistance than rubber-tyred road vehicles, so passenger and freight cars (carriages and wagons) can be coupled into longer trains. The rail transport operations, operation is carried out by a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Train
In rail transport, a train (from Old French , from Latin , "to pull, to draw") is a series of connected vehicles that run along a railway track and transport people or freight. Trains are typically pulled or pushed by locomotives (often known simply as "engines"), though some are self-propelled, such as multiple units. Passengers and cargo are carried in railroad cars, also known as wagons. 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. 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 locomotive in the United Kingdom in 1804, trains rapidly spread around the world, allowing freight and passengers to move over land faster and cheaper than ever possible before. Rapid transit and trams were first built in the late 180 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Locomotive
A locomotive or engine 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 (see CargoSprinter). Traditionally, locomotives pulled trains from the front. However, push-pull operation has become common, where the train may have a locomotive (or locomotives) at the front, at the rear, or at each end. Most recently railroads have begun adopting DPU or distributed power. The front may have one or two locomotives followed by a mid-train locomotive that is controlled remotely from the lead unit. __TOC__ Etymology The word ''locomotive'' originates from the Latin 'from a place', ablative of 'place', and the Medieval Latin 'causing motion', and is a shortened form of the term ''locomotive engine'', which was ...

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] |
Zig Zag (railway)
A railway zig zag or switchback, is a method of 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, that has six full zig zags and three spirals. Advantages Zig zags tend to be cheaper to construct because the grades required are discontinuous. Civil engineers can generally find a series of shorter segments going back and forth up the side of a hill more easily and with less grading than they can a continuous grade, which must contend w ...

Khyber Pass
The Khyber Pass (خیبر درہ) 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. 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 strategic military choke point for various states that controlled it. Following Asian Highway 1 ( AH1), the summit of the pass at Landi Kotal is inside Pakistan, descending to Jamrud, about from the Afghan border. The inhabitants of the area are predominantly from the Afridi and Shinwari tribes of Pashtuns. Geography The Khyber Pass is a mountain pass in the Khyber Pakhtunkhwa province of Pakistan, on the border with Afghanistan ( Nangarhar Province).

New South Wales XPT
The New South Wales ''XPT'' (short for eXpress Passenger Train) is a class of diesel-powered passenger trains built by Comeng and ABB Transportation. Based on the British Rail designed Intercity 125 High Speed Train, each XPT set is made up of two XP Power Cars in a push-pull formation coupled to between four and seven carriages. The first sets entered service under the State Rail Authority in 1982 and now operate under NSW TrainLink, running on long-distance regional and interstate North Coast, Main Western and Main Southern lines throughout New South Wales and interstate into Victoria and Queensland. History Development Improving public transport was a major issue in the 1976 State Election in New South Wales and one of the commitments of the incoming Wran Government was to buy new rolling stock for country rail services. In January 1978, the Public Transport Commission invited tenders for 25 high-speed railcars similar to the Prospector railcars delivered by Com ...
