British Railways Class 33035 was built by the Birmingham Railway Carriage and Wagon Company as part of a batch delivered to the Southern Region of British Railways in May 1961. It features an 8 cylinder Sulzer diesel engine rated at 1550hp driving Crompton Parkinson traction motors earning the class the nickname “Cromptons”. This class of locomotive spent most of their working lives hauling passenger trains around the Southern Region, particularly Electric Multiple Units that were working on non-electrified routes. As a result all were fitted with Electric Train Heating (ETH) and some received multiple unit working controls.

When new the locomotive was turned out in British Railways locomotive green and initially allocated to Hither Green wearing the number of D6553. Later in the 1970s the locomotive received British Railways corporate blue livery and was renumbered to 33035 under the then-new Total Operations Processing System (TOPS) scheme. Towards the end of the locomotives service career it was repainted into Network SouthEast livery, becoming one of only two Class 33 locomotives to receive this livery.

The locomotive was officially withdrawn from active service at Stewarts Lane depot in October 1996 although it is believed that it hadn‟t hauled any trains since 1994. It was purchased for preservation in 1997 and moved to Barrow Hill, Chesterfield. Whilst there 33035 has been extensively restored and painted into British Rail Blue livery. The Pioneer Diesel Locomotive Group are the proud restorers and carers of this locomotive.
