Network Rail is pursuing a policy of closing level crossings at the rate of over 100 a year in the interests of safety, and replacing them with road bridges or footbridges. [22] The number of level crossings on rail lines controlled by Network Rail went from 7,937 in 2003–04 [23] to 6,322 in 2013–14, [24] and 5,887 by 2016–17. [25]
In the United Kingdom, such crossings are categorised as manually-controlled barriers (MCB) because they are almost always controlled from a signal box or centre. Some are known as MCB-CCTV level crossings, where they are supervised by video link to the signal box from which they are remotely controlled.
These were standard all across the network until mechanised barriers started to be introduced. These were either automatic or operated by a signalman adjacent to the crossing. After the major Hixon rail crash in 1968, the design of level crossings started to change, and all mechanised crossings had to have a preliminary amber light fitted. The ...
The small footprint barrier design originated from North America but is assembled and tested at the manufacturing site in Chippenham, UK for UK installations. The barrier controls are at eye level which makes installation and maintenance procedures quicker and more ergonomic for the on-site teams.
A level crossing is an intersection where a railway line crosses a road, path, or (in rare situations) airport runway, at the same level, [1] as opposed to the railway line or the road etc. crossing over or under using an overpass or tunnel.
Efforts to remove level crossings are done in the UK by Network Rail and in Melbourne as part of the Level Crossing Removal Project. The London Extension of the Great Central Railway , built between 1896 and 1899, was the first fully grade-separated railway of this type in the UK.
Level crossing signals are electronic warning devices for road vehicles at railroad level crossings. Level crossings can be operated in various ways. In some countries such as the UK, the warning devices are more often than not activated by remote control, I.e. an operator pressing buttons.
In contrast to the American "railroad crossing", Australian signs say "railway crossing" or "tramway crossing". (Most cases where a tram in its own right-of-way crosses a road do not use a crossbuck and so are regular intersections rather than level crossings.) Different countries may classify the sign differently.
