Electric Locomotives
Electric locomotives collect power in the form of electricity from either overhead catenary wires, or a ground level third rail.
The locomotives do not have a diesel engine/generator and do not produce any power on board. Thus, they are not a self contained locomotive capable of movement when not collecting electrical power from the external source.
The North Eastern Railway and later London & North Eastern Railway electrified routes were energised at 1500v Direct Current from overhead catenary.
The London Midland Region electrification project was commissioned from Crewe to Manchester in 1960, and then in 1961 to Liverpool, and by 1965 to London Euston. The catenary was energised at 25,000v Alternating Current.
The London & South Western Railway in 1915 adopted a third rail system of electrical power supply at 630v Direct Current. After the grouping the Southern Railway, and then under BR the Southern Region, extended this to almost all lines at 660/750v DC. This has become the largest electrified third rail system in the world.
London Underground uses a four-rail system at a combined 630v DC.
