Where third rail systems have level crossings, there is a gap in the third rail over the level crossing, but this does not necessarily interrupt the power supply to trains since they may have current collectors on multiple cars.
To mitigate investment costs, the Rotterdam Metro, basically a third-rail-powered system, has been given some outlying branches built on surface tracks as light rail (called sneltram in Dutch), with numerous level crossings protected with barriers and traffic lights. These branches have overhead wires.
Most of Hong Kong's railway network is either underground or on elevated viaducts, meaning that level crossings are rare. However, level crossings continue to exist on the MTR Light Rail network, and one such level crossing was the site of a level crossing accident in 1994. [30]
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. However, the majority of countries have automated systems.
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]
Tibbits Avenue would be put into a 24 foot (7.3 m)-wide tunnel underneath the rail line done about 810 feet (250 m) north of the existing crossing with a clearance of 12 feet (3.7 m). Railroad Avenue would be put in a 75 foot (23 m)-wide tunnel, with a 50 foot (15 m)-wide roadway and sidewalks, with a maximum clearance of 13 feet (4.0 m).
A live rail was outside the running rails 3 ft 11 + 1 ⁄ 2 in (1.207 m) from the centre of the track and 3 in (76 mm) above the top of the running rails. [1] A return rail, cross-bonded to the running rails, was positioned centrally between the tracks. [2] The route was 23 + 1 ⁄ 2 miles (37.8 km) long and gaps were left at 46 level crossings.
