Buffer Stop
A buffer stop, bumper, bumping post, bumper block or stopblock (US), is a device to prevent railway vehicles from going past the end of a physical section of track. The design of the buffer stop is dependent, in part, on the kind of couplings that the railway uses, since the coupling gear is the first part of the vehicle that the buffer stop touches. The term "buffer stop" is of British origin, since railways in Great Britain principally use buffer-and-screw couplings between vehicles. Types Several different types of buffer stop have been developed. They differ depending on the type of coupler used and on the intended application. * Buffer stops with anticlimbers. These are particularly important for passenger railway applications, because the anticlimbers reduce the likelihood of telescoping of the railroad cars during a head-on impact. * Buffer stops for a knuckle coupler or an SA3 coupler (centrally positioned between the two rails) * Buffer stops with traditional " ...

Railroad Car
A railroad car, railcar (American and Canadian English), railway wagon, railway carriage, railway truck, railwagon, railcarriage or railtruck (British English and UIC), also called a train car, train wagon, train carriage or train truck, is a vehicle used for the carrying of cargo or passengers on a rail transport system (a railroad/railway). Such cars, when coupled together and hauled by one or more locomotives, form a train. Alternatively, some passenger cars are self-propelled in which case they may be either single railcars or make up multiple units. The term "car" is commonly used by itself in American English when a rail context is implicit. Indian English sometimes uses "bogie" in the same manner, though the term has other meanings in other variants of English. In American English, "railcar" is a generic term for a railway vehicle; in other countries "railcar" refers specifically to a self-propelled, powered, railway vehicle. Although some cars exist for the railroa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paris
Paris () is the capital and most populous city of France, with an estimated population of 2,165,423 residents in 2019 in an area of more than 105 km² (41 sq mi), making it the 30th most densely populated city in the world in 2020. Since the 17th century, Paris has been one of the world's major centres of finance, diplomacy, commerce, fashion, gastronomy, and science. For its leading role in the arts and sciences, as well as its very early system of street lighting, in the 19th century it became known as "the City of Light". Like London, prior to the Second World War, it was also sometimes called the capital of the world. The City of Paris is the centre of the Île-de-France region, or Paris Region, with an estimated population of 12,262,544 in 2019, or about 19% of the population of France, making the region France's primate city. The Paris Region had a GDP of €739 billion ($743 billion) in 2019, which is the highest in Europe. According to the Economist Intelli ...

Gare Montparnasse
Gare Montparnasse (; Montparnasse station), officially Paris-Montparnasse, one of the six large Paris railway termini, is located in the 14th and 15th arrondissements. The station opened in 1840, was rebuilt in 1852 and relocated in 1969 to a new station just south of the original location – where subsequently the prominent Montparnasse Tower was constructed. It is a central element to the Montparnasse area. The original station is noted for the Montparnasse derailment, where a steam train crashed through the station in 1895, an event captured in widely known photographs – and reproduced in full scale in several locations. The station serves intercity TGV trains to the west and southwest of France including Tours, Bordeaux, Rennes and Nantes, and suburban and regional services on the Transilien Paris – Montparnasse routes. There is also a metro station. Gare Montparnasse is the only mainline terminus in Paris not directly connected to the RER system, though the Mo ...

Train Wreck At Montparnasse 1895
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 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. Passengers and cargo are carried in railroad cars, also known as wagons. Trains are designed to a certain Track gauge, 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 Horsecar, powered by horses or Cable railway, 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 pos ...

Scarborough Railway Station
Scarborough railway station, formerly Scarborough Central, is a Grade II listed station serving the seaside town of Scarborough, North Yorkshire. It lies east of York and is one of the eastern termini on the North TransPennine route, operated by TransPennine Express. The station is also at the northern end of the Yorkshire Coast line and is reputed to have the longest station seat in the world at long. From 1907 until 2010 the station approaches were controlled from a 120-lever signal box named Falsgrave (at the outer end of platform 1 and close to the former excursion station at ). In its final years Falsgrave box controlled a mixture of colour-light and semaphore signals, including a gantry carrying 11 semaphores. The signal box was decommissioned in September 2010 and the gantry was dismantled and removed in October 2010. Its new home was Grosmont railway station, on the North Yorkshire Moors Railway. The new signalling is a relay-based interlocking with two- and three-asp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sand Drag
Catch points and trap points are types of turnout which act as railway safety devices. Both work by guiding railway carriages and trucks from a dangerous route onto a separate, safer track. Catch points are used to derail vehicles which are out of control (known as ''runaways'') on steep slopes. Trap points are used to protect main railway lines from unauthorised vehicles moving onto them from sidings or branch lines. Either of these track arrangements may lead the vehicles into a sand drag or safety siding, track arrangements which are used to safely stop them after they have left the main tracks. A derail is another device used for the same purposes as catch and trap points. Trap points ''Trap points'' are found at the exit from a siding or where a secondary track joins a main line. A facing turnout is used to prevent any unauthorised movement that may otherwise obstruct the main line. The trap points also prevent any damage that may be done by a vehicle passing ...

Shock Absorber
A shock absorber or damper is a mechanical or hydraulic device designed to absorb and damp shock impulses. It does this by converting the kinetic energy of the shock into another form of energy (typically heat) which is then dissipated. Most shock absorbers are a form of dashpot (a damper which resists motion via viscous friction). Description Pneumatic and hydraulic shock absorbers are used in conjunction with cushions and springs. An automobile shock absorber contains spring-loaded check valves and orifices to control the flow of oil through an internal piston (see below). One design consideration, when designing or choosing a shock absorber, is where that energy will go. In most shock absorbers, energy is converted to heat inside the viscous fluid. In hydraulic cylinders, the hydraulic fluid heats up, while in air cylinders, the hot air is usually exhausted to the atmosphere. In other types of shock absorbers, such as electromagnetic types, the dissipated energy can be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
