Wimbledon Loop
The Sutton Loop Line, Retrieved 2012-01-12 also known as the Wimbledon Loop, is a railway line that diverges from the Portsmouth Line at Streatham South junction and rejoins it near Sutton station. Trains leave southwards from to enter the loop and then return going northwards. The short section between station and West junction is known as the "Wall of Death", possibly due to the very steep concrete walls to the cutting on both sides and the sharpness of the curve which resemble the motorcycle ride at a funfair. Stations In a clockwise direction round the loop, the stations are: * Sutton * * * * * * * * * Infrastructure Traction current is supplied at 750 volts DC via the third rail. The supply for this is overseen by Selhurst Electrical Control Room. Signalling is Track Circuit Block with multiple aspect colour light signals, controlled from Three Bridges rail operating centre. The line is double track throughout, except where a short bi-directionally signalled ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heavy Rail
Various terms are used for passenger railway lines and equipment; the usage of these terms differs substantially between areas: Rapid transit A rapid transit system is an electric railway characterized by high speed (~) and rapid acceleration. It uses passenger railcars operating singly or in multiple unit trains on fixed rails. It operates on separate rights-of-way from which all other vehicular and foot traffic are excluded (i.e. is fully grade-separated from other traffic). It uses sophisticated signaling systems, and high platform loading. Originally, the term ''rapid transit'' was used in the 1800s to describe new forms of quick urban public transportation that had a right-of-way separated from street traffic. This set rapid transit apart from horsecars, trams, streetcars, omnibuses, and other forms of public transport. A variant of the term, ''mass rapid transit (MRT)'', is also used for metro systems in Southeast Asia and Taiwan. Though the term was almost alway ...

Railway Loop Lines
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 facil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Thameslink (route)
Thameslink is a 24-hour main-line route in the British railway system, running from , , , and via central London to Sutton, , , Rainham, , , , and . The network opened as a through service in 1988, with severe overcrowding by 1998, carrying more than 28,000 passengers in the morning peak. All the services are currently operated by Govia Thameslink Railway. The Thameslink Programme was a major £5.5billion scheme to increase capacity on the central London section by accommodating more frequent and longer trains, and providing additional routes and destinations. The new services began operating in 2018. In 2016, new Class 700 trains started operating on the route and replaced the Class 319, Class 377 and Class 387 trains which were withdrawn and transferred elsewhere. Route Much of the original route is over the Brighton Main Line (via London Bridge) and the southern part of the Midland Main Line, plus a suburban true loop (circuit) serving Sutton.

St Albans City Railway Station
St Albans City railway station, also known simply as St Albans, is one of two railway stations serving the city of St Albans in Hertfordshire, England (the other being ). The 'City' station is the larger of the two, as it is on the better-connected Midland Main Line from London St Pancras, being served by Govia Thameslink trains on the Thameslink route. History The station was built by the Midland Railway in 1868, on its extension to St Pancras. St Albans was famous for producing watercress, which was sent in lots to London and Manchester. The other station, , was built by the London and North Western Railway in 1858. There was originally a further station called '' London Road'', built by the Hatfield and St Albans Railway in 1863 to connect with the Great Northern Railway. Description The station has four platforms, two for each direction: one "fast" and one "slow". The main entrance, ticket office, multi-storey car park, taxi rank and bus connections are on Statio ...

Tramlink
London Trams, previously Tramlink and Croydon Tramlink, is a light rail tram system serving Croydon and surrounding areas in South London, England. It began operation in 2000, the first tram system in the London region since 1952. It is managed by London Trams, a public body part of Transport for London (TfL), and has been operated by FirstGroup since 2017. Tramlink is one of two light rail networks in Greater London, the other being the Docklands Light Railway. The network consists of 39 stops along of track, on a mixture of street track shared with other traffic, dedicated track in public roads, and off-street track consisting of new rights-of-way, former railway lines, and one right-of-way where the Tramlink track runs parallel to a third rail-electrified Network Rail line. The network's lines coincide in central Croydon, with eastern termini at Beckenham Junction, Elmers End and New Addington, and a western terminus at Wimbledon, where there is an interchange for London ...

Three Bridges Rail Operating Centre
Three Bridges railway station is located in and named after the village of Three Bridges, which is now a district of Crawley, West Sussex, England. It is at the point where the Arun Valley Line diverges from the Brighton Main Line and Thameslink, down the line from via . History The original Italianate style railway station on the East side of the line at Three Bridges was opened in July 1841 by the London and Brighton Railway at a point next to their proposed branch to Horsham. It was designed by the architect David Mocatta, and was one of a series of standardised modular buildings used by the railway. This building was demolished 5 May 1985. Mocatta's plans for the station indicate that it was originally going to be known as "Crawley" but according to ''The London and Brighton railway guide'', of 1841 and the 1846 timetable it was named "Three Bridges" from the time it was opened. Enlargement The London and Brighton Railway merged with others to become the London Brighton ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Signalling Block System
Signalling block systems enable the safe and efficient operation of railways by preventing collisions between trains. The basic principle is that a track is broken up into a series of sections or "blocks". Only one train may occupy a block at a time, and the blocks are sized to allow a train to stop within them. That ensures that a train always has time to stop before getting dangerously close to another train on the same line. The block system is referred to in the UK as the ''method of working'', in the US as the ''method of operation'', and in Australia as ''safeworking''. In most situations, a system of signals is used to control the passage of trains between the blocks. When a train enters a block, signals at both ends change to indicate that the block is occupied, typically using red lamps or indicator flags. When a train first enters a block, the rear of the same train has not yet left the previous block, so both blocks are marked as occupied. That ensures there is slight ...

Track Circuit
A track circuit is an electrical device used to prove the absence of a train on rail tracks to signallers and control relevant signals. An alternative to track circuits are axle counters. Principles and operation The basic principle behind the track circuit lies in the connection of the two rails by the wheels and axle of locomotives and rolling stock to short an electrical circuit. This circuit is monitored by electrical equipment to detect the absence of the trains. Since this is a safety appliance, fail-safe operation is crucial. Hence the circuit is designed to indicate the presence of a train when failures occur. On the other hand, false occupancy readings are disruptive to railway operations and must be minimized. Track circuits allow railway signalling systems to operate semi-automatically, by displaying signals for trains to slow or stop in the presence of occupied track ahead of them. They help prevent Train dispatcher, dispatchers and Manual block, operators from ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Third Rail
A third rail, also known as a live rail, electric rail or conductor rail, is a method of providing electric power to a railway locomotive or train, through a semi-continuous rigid conductor placed alongside or between the rails of a railway track. It is used typically in a mass transit or rapid transit system, which has alignments in its own corridors, fully or almost fully segregated from the outside environment. Third rail systems are usually supplied from direct current electricity. Modern tram systems, street-running, avoid the risk of electrocution by the exposed electric rail by implementing a segmented ground-level power supply, where each segment is electrified only while covered by a vehicle which is using its power. The third-rail system of electrification is not related to the third rail used in dual gauge railways. Description Third-rail systems are a means of providing electric traction power to trains using an additional rail (called a "conductor rail") fo ...
