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 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 sleepers (ties) set in 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 frictional resistance than rubber-tyred road vehicles, so passenger and freight cars (carriages and wagons) can be coupled into longer trains. The operation is carried out by a railway company, providing transport between train stations or freight customer facilit ...

Application Of Railway Signals
The application of railway signals on a rail layout is determined by various factors, principally the location of points of potential conflict, as well as the speed and frequency of trains and the movements they require to make. Non-provision of signals Before discussing the application of signals, it is useful to highlight some situations where signals are ''not'' required: * Sidings generally need not be signalled, as all movements within them are made cautiously at low speed. * Tram lines frequently employ "running on sight" without any signals (similar to road traffic). * Where movement authorities are passed to drivers exclusively by means other than fixed signals (e.g. by written or verbal authority), token, or cab signalling. Purpose of signals Signals exist primarily to pass instructions and information to drivers of passing trains. The driver interprets the signal's indication and acts accordingly. The most important indication is 'danger', which means 'stop'. N ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Level Crossing
A level crossing is an intersection where a railway line crosses a road, Trail, path, or (in rare situations) airport runway, at the same level, as opposed to the railway line crossing over or under using an Overpass#Railway, overpass or tunnel. The term also applies when a light rail line with separate Right-of-way (railroad), right-of-way or reserved track crosses a road in the same fashion. Other names include railway level crossing, railway crossing (chiefly international), grade crossing or railroad crossing (chiefly American), road through railroad, criss-cross, train crossing, and RXR (abbreviated). There are more than 100,000 level crossings in Europe and more than 200,000 in North America. History The history of level crossings depends on the location, but often early level crossings had a Flagman (rail), flagman in a nearby booth who would, on the approach of a train, wave a red flag or lantern to stop all traffic and clear the tracks. Gated crossings bec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Signal Passed At Danger
A signal passed at danger (SPAD), known in the United States as a stop signal overrun and in Canada as passing a stop signal, is an event on a railway where a train passes a stop railway signal, signal without authority. In the United States and Canada, this may be known colloquially as ''wikt:run a red light, running a red'', though this idiom principally refers to automobiles passing red traffic signals. The name derives from red Railway_signal#Colour_light_signals, colour light signals and horizontal Railway semaphore signal, semaphore signals in the United Kingdom, which are said to be ''at danger'' when they indicate that trains must stop (also known as the signal being ''on''). This terminology is not used in North America where not all red signals indicate stop. In the UK, the alternative description signal passed at red (S.P.A.R.) is used where a signal changes to red in front of a train due to either a technical fault or in an emergency, such that the train is unable t ...
