ADB975397 – Test Car 2

An interesting project is currently taking place at GCR, where an important vehicle used in railway testing is being restored...

Test Car 2 was originally built at Wolverton in 1962 as Mk 1 Brake Second Corridor (BSK) number 35386 as part of Lot 30699 and fitted with Commonwealth bogies.

The coach was temporarily adapted for use by the Department of Mechanical & Electrical Engineers (DM&EE) as a test car in 1974, and renumbered ADB975397. This was after the previous Test Car 2, DE320041 was irreparably damaged after a failed slip/brake test. The new Test Car 2 received further modifications in 1976 including changes to the interior layout and installation of a generator.

Between 1974 and 2006 Test Car 2, based at the Railway Technical Centre in Derby was mostly used for Slip/Brake testing of vehicles on the WCML between Crewe & Winsford. On occasions, Slip/Brake testing was also carried out on the ECML north of York, most notably a Mk 3 coach in 1985. Testing was required to verify the braking characteristics of new vehicles and the best way to do this was to slip them and allow them to brake on their own without influence from any other vehicle.

When not in use for Slip/Brake tests, the coach was often seen coupled with Test Car 1 to provide additional braking effort when carrying out vehicle ride testing at higher speeds.

In 1994 an unusually large amount of instrumentation was installed when Test Car 2 was used as the main test coach for the pantograph and traction performance testing of Class 92 locomotives. The Class 92 tests included four days of operations between the Dollands Moor freight yard, through the Channel Tunnel to the Fréthun freight yard near Calais.

When British Rail was privatised, Serco Railtest took over the role of testing vehicles until slip testing paths became difficult to arrange and Test Car 2 was retired to the Old Dalby Test Track in 2011.

In 2016 Test Car 2 was lined up for disposal and saved by a GCR volunteer. It was moved to the GCR and now falls under the care of the Quorn Wagon Group who are currently in the process of restoring the vehicle to its BR testing glory.
