BTP also polices the London Underground, Docklands Light Railway, the West Midlands Metro, Tramlink, part of the Tyne and Wear Metro, Glasgow Subway and the London Cable Car.
BTP, in conjunction with the French National Police (under the Border Police unit) – Police aux Frontières – police the international services operated by Eurostar.
The force is funded primarily by the rail industry.
Coat-of-Arms: Across the centre runs a broad band of silver called a fesse; this is to symbolise the broad highways – roads. On the silver fesse are two wavy bars called barrulets, to represent the steel railways.The fesse is doubly “cottised”. In the upper part of the shield (called the chief – or “in chief) are three wheels, symbolising locomotives and rolling stock; in the base of the shield is a portcullis with chains which symbolise a gateway, entrance or port. Thus the four principal departments controlled by the British Transport Commission: British Railways, Roads and Road Transport, Canals and Waterways, Ports and Harbours are represented.
1949 to 1963 it was known as the British Transport Commision Police.
