Bulleid/Raworth Co-Co Electric Locomotives (Class 70)

Then in 1948 British Railways constructed a third locomotive, Nº20003. It looked significantly different with its cab front being similar to the latest EMUs, by this time being the slab front design with larger windows of the "Queen Mary" Subs. This locomotive was also 1ft 6in longer, weighed 105 tons, was capable of 45000lb tractive effort, had fewer sanding boxes and a larger boiler water tank on the underframe between the bogies. Included from scratch were refinements learned from the earlier two and more modern electrical equipment. Nº20003 was also introduced in malachite livery with yellow lining but with yellow British Railways lettering and numbering in the Gill Sans font.

Various modifications happened to these locomotives throughout their lives. MU jumpers were an early addition to CC1/2 as were marker lights. Three sandboxes from each bogie were also removed from the earlier pair. CC1 was built with a headcode panel which was subsequently modified to be a boxed headlight but later converted back to a headcode panel. CC2 (20002) received a headcode panel in later life but 20003 never received did They were classified as class 70 under TOPS although photographic evidence suggests they never carried a TOPS format number.

They settled down to a productive but unremarkable life doing exactly what they were designed to do. They were closely associated with Victoria-Newhaven boat trains, assuming this duty from the Brighton Atlantics in 1949. They were popular, powerful, reliable and efficient locomotives though no more were produced and the Southern's next electrical locomotives were the HA (later class 71) design introduced in 1959. CC1 and 2 were withdrawn by 1969 and curiously the younger CC3 in October 1968, despite their virtues all being victims (like other classes) of being non standard.

 
From 1949/50 they adopted the initial black and aluminium colour scheme chosen by British Railways for diesel, electric and gas turbine locomotives, however prior to this in 1948/9 Nº20002 carried an experimental light blue livery and was exhibited in this colour to the railway executive at Kensington Addison Road station. From the late 1950s they carried green livery (thought to be a modified malachite) with a red and white line half way up the side stopping short of the cab doors and a pale green frame. Nº20001 was withdrawn in BR blue with full yellow ends, by which time it had also gained twin air horns on the roof.

20001 Nº20001 at Nehaven Harbour whilst working The Sussex Venturer Rail Tour on 4th January 1969. This was almost certainly the last tour to visit the Uckfield - Lewes line and the last passenger train to use the Polegate - Stone Cross Junction line.

Nº20002 seen in its later days at Brighton depot, presumably after withdrawal as the collector beams have been removed. As far as can be seen through the dirt the livery is still the unlined mid (coach stock?) green it received during a September 1964 repaint at Eastleigh but by the time of this picture (between April and September 1969?*) with full yellow ends added. A headcode panel and rooftop airhorns were added at or prior to the 1964 repaint.
