Manufacturer description

We are delighted to welcome Bachmann Branchline’s stunning rendition of the Prototype Power Car from the High Speed Diesel Train (HSDT – otherwise known as the HST) to the Bachmann Collectors Club range, with this model depicting No. 41001 in its Departmental years when used as part of the Railway Technical Centre (RTC).

Having paved the way for the production HSTs, which would go on to become one of Britain’s most iconic trains of all time, the two prototype power cars were taken out of use once the production versions were in service. Thankfully, they were granted a new lease of life in Departmental use and the pair joined the RTC fleet, with No. 41001 becoming ADB975812 and gaining full yellow ends as far back as the cab doors and over the cab roof.

CLASS 41 PROTOTYPE HSDT POWER CAR HISTORY

During the 1960s, in its quest for high speed travel and reduced journey times, British Rail set about developing new trains that could run at an increased line speed of 125mph. The HSDT was one solution, and a prototype train was authorised by British Rail in August 1970, with the first vehicles delivered to the Railway Technical Centre (RTC) for testing and type approval less than two years later in the summer of 1972.

Conceived by the Railway Technical Centre, the train owed a great deal of its design to the Western Region, as many of the RTC’s design staff came from Swindon. The experimental train comprised two power cars, along with a set of carriages that would be the prototypes for BR’s Mk3 coaching stock. The power cars were built by British Rail Engineering Limited (BREL) at Crewe Works, whilst the Mk3s were constructed at BREL’s Litchurch Lane site in Derby. Under the Total Operations Processing System (TOPS) the power cars were designated Class 41, with the complete train allocated Class 252.

With development of the Advance Passenger Train (APT) ongoing alongside that of the HST, many saw the APT as the future of British rail travel, with the HST being little more than a stopgap. However, whilst the APT project suffered repeated delays, the prototype HST had already entered service and was such a success that production versions were quickly ordered. Various changes were made between the prototype and production trains, most notably the revised front end of the power cars. A total of 95 production High Speed Trains were built and the HST went on to become one of the most successful trains to have operated on the British railway network.

With the introduction of the production HSTs, the prototype power cars were withdrawn from serviced in late-1976 and both entered Departmental stock, returning to the RTC in Derby where they were used to haul various test trains for a number of years. By the mid-1980s the two vehicles had been stored out of use and whilst one was later scrapped, the other, No. 41001, was preserved as part of the National Collection and now takes pride of place at the National Railway Museum’s Locomotion Museum in Shildon, Country Durham.
