British Rail Class 419
The British Rail Class 419 Motor Luggage Vans (or MLV) were battery electric multiple unit cars built from 1959-61 by BR at Eastleigh Works.[2][6] The units were also fitted with batteries to allow them to operate over the short-distance of non-electrified quayside lines at Dover and Folkestone.[8] The MLVs were withdrawn from traffic in 1991-92, with the closure of Dover Western Docks railway station and the end of the boat train services.[8] The design of the units was based on an earlier vehicle, numbered 68000, which was used as a parcels van on the Tyneside DC electrified network.When the South Tyneside network was de-electrified in 1967, the unit was initially transferred for use on the Southport to Liverpool electric line before being withdrawn.
