Catch Points
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 passin ...

Railway Signal
A railway signal is a visual display device that conveys instructions or provides warning of instructions regarding the driver’s authority to proceed. The driver interprets the signal's indication and acts accordingly. Typically, a signal might inform the driver of the speed at which the train may safely proceed or it may instruct the driver to stop. Application and positioning of signals Originally, signals displayed simple stop or proceed indications. As traffic density increased, this proved to be too limiting and refinements were added. One such refinement was the addition of distant signals on the approach to stop signals. The distant signal gave the driver warning that they were approaching a signal which might require a stop. This allowed for an overall increase in speed, since train drivers no longer had to drive at a speed within sighting distance of the stop signal. Under timetable and train order operation, the signals did not directly convey orders to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Derailment
In rail transport, a derailment occurs when a rail vehicle such as a train comes off its rails. Although many derailments are minor, all result in temporary disruption of the proper operation of the railway system and they are a potentially serious hazard. A derailment of a train can be caused by a collision with another object, an operational error (such as excessive speed through a curve), the mechanical failure of tracks (such as broken rails), or the mechanical failure of the wheels, among other causes. In emergency situations, deliberate derailment with derails or catch points is sometimes used to prevent a more serious accident. History The first recorded train derailment in history is known as the Hightstown Rail Accident in New Jersey that occurred on November 8, 1833. The train was traveling between Hightstown and Spotswood New Jersey and derailed after an axle broke on one of the carriages as a result of a journal box catching fire. The derailment resulted in ...

Castle Cary Railway Station
Castle Cary railway station is on the Reading to Taunton line south west of London Paddington and the Bristol to Weymouth line south of Bristol Temple Meads. The two routes share tracks between Westbury and Castle Cary stations and are both operated by Great Western Railway, which also manages the station. The station is north of the town of Castle Cary and south of Shepton Mallet in a largely rural area of Somerset, England. History Castle Cary station was originally on the Wilts, Somerset and Weymouth Railway, a railway that linked the Great Western Railway (GWR) at Chippenham with Weymouth. The line was authorised in 1845, was acquired by the GWR in 1850, reached Castle Cary on 1 September 1856, and was completed throughout in 1857. For the remainder of the 19th century, the GWR's principal route from London Paddington station to Exeter, Plymouth and Penzance was an indirect one via Bristol Temple Meads (the so-called ''Great Way Round''). However, in 1895 the GWR di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bristol Parkway Railway Station
Bristol Parkway, on the South Wales Main Line, is in the Stoke Gifford area in the northern suburbs of the Bristol conurbation. It is from London Paddington. The station was opened in 1972 by British Rail, and was the first in a new generation of park and ride/parkway stations. It is the third-most heavily used station in the West of England local authority area, after Bristol Temple Meads and . There are four platforms, and a well-equipped waiting area. The station is managed by Great Western Railway, who provide most of the trains at the station, with CrossCountry providing the rest. Electrification using 25 kV 50 Hz AC overhead system reached Bristol Parkway in late 2018, and electric trains in the Swindon and London direction commenced passenger service on 30 December 2018. This is part of the 21st-century modernisation of the Great Western Main Line. Description Bristol Parkway is located in the unitary authority of South Gloucestershire, in the Stoke Gifford area o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Wales Main Line
The South Wales Main Line ( cy, Prif Linell De Cymru), originally known as the London, Bristol and South Wales Direct Railway or simply as the Bristol and South Wales Direct Railway, is a branch of the Great Western Main Line in Great Britain. It diverges from the core London-Bristol line at Royal Wootton Bassett beyond Swindon, first calling at Bristol Parkway, after which the line continues through the Severn Tunnel into South Wales.

Hornsby Railway Station
Hornsby railway station is located at the junction of the Main Northern and North Shore lines, serving the Sydney suburb of Hornsby. It is served by Sydney Trains T1 North Shore Line and T9 Northern Line services and NSW TrainLink Intercity and regional services. History The station opened on 17 September 1886 as Hornsby, but was renamed Hornsby Junction on 1 November 1894. This was due to the construction of Normanhurst station to the south, which was initially named Hornsby as it was located in what was the more densely populated area of Hornsby at the time. Naming the station Hornsby Junction was an attempt to avoid confusion, but it was realised that having two Hornsby stations was still very confusing. On 1 May 1900, the suburb and station to the south was renamed Normanhurst, and Hornsby Junction reverted to Hornsby. On 1 January 1890, Hornsby became a junction station with the opening of the North Shore line to St Leonards. In 1894, a third platform was built alon ...

Locomotive
A locomotive or engine is a rail transport vehicle that provides the Power (physics), 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 (rail), 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 train, 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 language, Latin 'from a place', Ablative case, ablative of 'place', and the Medieval Latin 'causing mot ...

Grade (slope)
The grade (also called slope, incline, gradient, mainfall, pitch or rise) of a physical feature, landform or constructed line refers to the tangent of the angle of that surface to the horizontal. It is a special case of the slope, where zero indicates horizontality. A larger number indicates higher or steeper degree of "tilt". Often slope is calculated as a ratio of "rise" to "run", or as a fraction ("rise over run") in which ''run'' is the horizontal distance (not the distance along the slope) and ''rise'' is the vertical distance. Slopes of existing physical features such as canyons and hillsides, stream and river banks and beds are often described as grades, but typically grades are used for human-made surfaces such as roads, landscape grading, roof pitches, railroads, aqueducts, and pedestrian or bicycle routes. The grade may refer to the longitudinal slope or the perpendicular cross slope. Nomenclature There are several ways to express slope: # as an ''angle'' of inc ...

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 " ...
