Background
The locomotives were initially needed, unusually, because of an electrification scheme. The 'Kent Coast scheme' was one of five major electrification schemes put forward by the 1955 Modernisation Plan. Under Stage 1 of the scheme, the majority of railway lines east of a line drawn between Reading and Portsmouth would be electrified. On secondary and branch lines not electrified, such as Tonbridge – West St. Leonards, diesel electric multiple units would work passenger services. The scheme involved the electrification of 250 route miles (400 km) of track at a cost of approximately £25m. The British Transport Commission (BTC) approved the scheme in February 1956. The Southern Region established an Electrification Committee, which met monthly from August 1955. On the South Eastern section, electrification was to be carried out in two phases.
