Testing with the DM&EE in the 1970's

Before joining the Testing & Performance Section of the Department of Mechanical & Electrical Engineering (DM&EE) at the RTC, Derby I spent 12 months at the LMR CM&EE - the Chief Mechanical and Electrical Engineers' department at Nelson Street, Derby.

I subsequently worked between 1971 and 1974 for the DM&EE during which time I was involved with testing in a number of different areas.

I worked initially on the 'Stress & Vibration' section which ran Test Car 4, the old WR dynamometer car converted in 1961 from a Hawksworth corridor coach and now preserved at Carnforth. When it first arrived at Derby to join the DM&EE's fleet of vehicles it was still in chocolate and cream livery, although it had been repainted into red and blue by the time I first saw it.

 Here is a list of the major tests with which I remember that I was involved with in the first year - there were probably a lot more which I've forgotten.

 I later moved to the 'Freight' Section  where I was involved with acceptance testing on freight vehicles. Pre-Nationalisation and BR conventional leaf spring suspension four wheeled wagons were commonplace in those days and the freight vehicles we tested were amongst the first of their type with modern suspensions. Both Gloucester C&W Floating axle and BSC pedestal suspensions were fitted to various new-build 4-wheeled vehicles. Bogie vehicles at the time were fitted with either Gloucester 3-piece bogies or later Y25C bogies. See the freight testing pages for more details.
