The Waterloo & City line, colloquially known as The Drain, is a London Underground shuttle line that runs between Waterloo and Bank with no intermediate stops. Its primary traffic consists of commuters from south-west London, Surrey and Hampshire arriving at Waterloo main line station and travelling forward to the City of London financial district. For this reason, the line has historically not operated on Sundays or public holidays, except in very limited circumstances. Following the COVID-19 pandemic, the line is currently only open on weekdays. It is one of only two lines on the Underground network to run completely underground, the other being the Victoria line.
Cannon Street station, also known as London Cannon Street, is a central London railway terminus and connected London Underground station in Travelcard zone 1 located on Cannon Street in the City of London and managed by Network Rail. It is one of two London termini of the South Eastern Main Line, the other being Charing Cross, while the Underground station is on the Circle and District lines, between Monument and Mansion House. The station runs services by Southeastern, mostly catering for commuters in southeast London and Kent, with occasional services further into the latter.
Embankment is a London Underground station in the City of Westminster, known by various names during its history. It is served by the Circle, District, Northern and Bakerloo lines. On the Bakerloo line and the Charing Cross branch of the Northern line, the station is between Waterloo and Charing Cross stations; on the Circle and District lines, it is between Westminster and Temple and is in Travelcard Zone 1. The station has two entrances, one on Victoria Embankment and the other on Villiers Street. The station is adjacent to Victoria Embankment Gardens and is close to Charing Cross station, Embankment Pier, Hungerford Bridge, Cleopatra's Needle, the Royal Air Force Memorial, the Savoy Chapel and Savoy Hotel and the Playhouse and New Players Theatres.
The Northern City Line is a commuter railway line in England, which runs from Moorgate station to Finsbury Park in London with services running beyond. It is part of the Great Northern Route services, and operates as the south-eastern branch of the East Coast Main Line (ECML). It is underground from Moorgate to Drayton Park in Highbury, from which point it runs in a cutting until joining the ECML south of Finsbury Park. Its stations span northern inner districts of Greater London southwards to the City of London, the UK's main financial centre. Since December 2015, its service timetable has been extended to run into the late evenings and at weekends, meeting a new franchise commitment for a minimum of six trains per hour until 23:59 on weekdays and four trains per hour at weekends.
Railway signalling (BE), also called railroad signaling (AE), is a system used to control the movement of railway traffic. Trains move on fixed rails, making them uniquely susceptible to collision. This susceptibility is exacerbated by the enormous weight and inertia of a train, which makes it difficult to quickly stop when encountering an obstacle. In the UK, the Regulation of Railways Act 1889 introduced a series of requirements on matters such as the implementation of interlocked block signalling and other safety measures as a direct result of the Armagh rail disaster in that year.
The Train Protection & Warning System (TPWS) is a train protection system used throughout the British passenger main-line railway network, and in Victoria, Australia.
A signal passed at danger (SPAD), known in the United States as a stop signal overrun (SSO) and in Canada as passing a stop signal, is an event on a railway where a train passes a stop signal without authority. This is also known as running a red.
The Clapham Junction rail crash occurred on the morning of 12 December 1988, when a crowded British Rail passenger train crashed into the rear of another train that had stopped at a signal just south of Clapham Junction railway station in London, England, and subsequently sideswiped an empty train travelling in the opposite direction. A total of 35 people died in the collision, while 484 were injured.
Automatic Warning System (AWS) is a railway safety system invented and predominantly used in the United Kingdom. It provides a train driver with an audible indication of whether the next signal they are approaching is clear or at caution. Depending on the upcoming signal state, the AWS will either produce a 'horn' sound, or a 'bell' sound. If the train driver fails to acknowledge a warning indication, an emergency brake application is initiated by the AWS. However if the driver correctly acknowledges the warning indication by pressing an acknowledgement button, then a visual 'sunflower' is displayed to the driver, as a reminder of the warning.
A wrong-side failure describes a failure condition in a piece of railway signalling equipment that results in an unsafe state. A typical example would be a signal showing a 'proceed' aspect when it should be showing a 'stop' or 'danger' aspect, resulting in a "false clear".
The Purley station rail crash was a train collision that occurred just to the north of Purley railway station in the London Borough of Croydon on Saturday 4 March 1989, leaving five dead and 88 injured. The collision was caused by the driver of one of the trains passing a signal at danger; he pleaded guilty to manslaughter and was sentenced to 12 months in prison plus six months suspended, although this was reduced to four months upon appeal, and in 2007 overturned. The Department of Transport report noted that the signal had a high incidence of being passed at danger and recommended that an automatic train protection system should be introduced without delay and in the interim a repeater for the signal that had been passed be installed.
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.
The railway signalling system used across the majority of the United Kingdom rail network uses lineside signals to control the movement and speed of trains.
The Spa Road Junction rail crash was an accident on the British railway system which occurred during the peak evening rush hour of 8 January 1999 at Spa Road Junction in Bermondsey, in South East London.
The Seer Green rail crash occurred on the morning of 11 December 1981 near Seer Green, Buckinghamshire, England between two four-car Class 115 diesel multiple units, killing one driver and three passengers.
The Charing Cross tube crash occurred on 17 May 1938 at about 09:55 hours, between Charing Cross and Temple stations. Six people were killed when a Circle line service ran into the rear of a District line service held at an automatic signal. A wiring error had caused the preceding signal to incorrectly display a green aspect.
The Marden rail crash occurred on 4 January 1969 near Marden, Kent, United Kingdom, when a passenger train ran into the rear of a parcels train, having passed two signals at danger. Four people were killed and 11 were injured. One person was awarded the British Empire Medal for his part in the aftermath of the collision.
On 3 February 2003, a Comeng electric multiple unit train rolled away from Broadmeadows station in Melbourne, Australia, before it ran for nearly 17 kilometres (11 mi) out of control without a driver and eventually crashed into another train about to depart Spencer Street station. Train controllers attempted several times to stop or redirect the train, but were limited in their ability to intervene, instead being forced to alter the route of other trains to avert a more serious collision. Eleven people on board the stationary train were injured; authorities did not know until after the crash if any passengers were on board the runaway. An investigation identified driver error as the cause of the accident, but the runaway event prompted significant debate about the role of government authorities and private operators in ensuring safety and reliability on the Melbourne rail network.
On the evening of 26 December 1962, cold weather and snow in and around Crewe had caused points to become frozen and trains were being detained at signals. About midway between Winsford and Crewe, the 13:30 Glasgow Central to London Euston Mid-Day Scot, hauled by an English Electric type 4 diesel, D215, with 13 coaches and 500 passengers, was stopped at a signal but the driver found the telephone to Coppenhall Junction, the next signal box ahead, out of order. Seeing the next signal ahead he decided to proceed down towards it and use the telephone there, but too fast. In the darkness he failed to notice the 16:45 express from Liverpool Lime Street to Birmingham New Street, hauled by an electric locomotive with eight coaches with 300 passengers, standing on the line ahead and collided with it at about 20 mph (32 km/h).
