Class 252 was the classification allocated to the prototype High Speed Train (HST) unit, numbered 252001.
History
When originally built, in 1972, the prototype High Speed Train (HST) units were considered to be formed of two locomotives at either end of a rake of carriages. As a result, the power cars were designated Class 41 and numbered 41001/41002, while the carriages were given numbers in the new Mark 3 carriage number series.
The 125 Group restored prototype powercar 41001 back to operational condition in 2013. This entailed a complete restoration of the vehicle and a fitment of a Paxman Valenta engine at Neville Hill TMD. The engine was successfully started in July 2013, and on 31 May 2014 the loco moved under its own power for the first time in over 30 years.41001 – Prototype HST Powercar 125 Group
