Test Car 1
|The first dynamometer car No:M45050 was
built by the Lancashire & Yorkshire Railway Company in 1912 and inherited
from the LMR
CM&EE. It was used for a number of tests in the 1960s and was last used on
riding tests with fly-ash wagons between Derby and South Wigston on 22nd
August 1967. It was finally withdrawn in November 1970.
It was, to my knowledge, never painted in the red and blue of RTC departmental vehicles and I doubt if it was ever known as Test Car 1.

|The second Test Car No:1 was converted in the early 1970s at the Engineering Development Unit, RTC, Derby from a former BR/WR autocoach which had been built in Swindon to Diagram A38, Lot 1736 in the early 1950s.|
This is the interior layout as I remember it in the 1970s
This vehicle was formerly numbered W233W which it still carried when it arrived at the RTC as well as its original maroon livery. A very attractive vehicle with its original GW bogies and long elegant buffers and it even had its warning bell.
Once it arrived it was quickly re-numbered DW150375 and re-painted into red and blue. It was temporarily equipped with a hand-cranked generator set to supply power for instrumentation (and the kettle) and became Test Car 1. Later a more permanent conversion was undertaken with a purpose-built generator room housing a diesel generator set. It was never altered inside apart from the creation of the generator room. The cooking facilities etc were within the main saloon. I don't think it even had a toilet but a chemical one was installed for emergencies.
Later it was equipped with B4 bogies and extended buffer mounts having Oleo pneumatic buffers fitted. No doubt safer and more efficient but this destroyed the vehicle's character.
It was repainted again in 1985 but this time into chocolate and cream for the GW150 celebrations although it never carried this livery as an autocoach. After this re-paint it lost its allegiance to either CM&EE or DM&EE as it only carried the name Test Car 1 and its running number.
After it was retired it was used as a support coach for the 7F Preservation Group at the Midland Railway Centre.
News from July 2013 suggested that the vehicle had moved to the South Devon Railway for restoration by the 'Locomotive 5542 Limited' Group.

Test Car 1 would have been similar to this before it came to the RTC and it may well be joining its sister coach soon

|Restored to its
maroon livery it was on display at the Matthew Kirtley museum, at
Swanwick Junction Midland Railway Centre. It still has the Oleo buffers
and B4 bogies
