The LMS
Dynamometer car No:1 M45050 was built by the L&Y in 1912 and was used by
the Testing Section at RTC until about 1970.
It is preserved at MRC, Butterley and has been restored to its original condition - have a look here for more information and pictures |

The first conversion to a Test Car carried out at RTC was a former BR/GWR autocoach built by BR in Swindon to Diagram A38, Lot 1736 and was formerly number W233W. It was re-numbered DW150375 not long after its arrival at RTC. Originally in maroon livery it was re-painted and equipped with a hand-cranked generator set and became Test Car 1. Later a more permanent conversion was undertaken. It is pictured on a test train in RTC yard with two BSC bogie tippler wagons circa 1972 |

Test Car 1 - note
its original GW bogies and long elegant buffers - on a test train with a
35t hopper. Also note the headcode on the class 47 - 1T 21 - a favourite at
the time. Author |

Test Car 1 was repainted into chocolate and cream for the GW150 celebrations in 1985 although it never carried this livery as an autocoach. Note that it now has B4 bogies and very much altered buffers. Another picture has come to light on Neale Harrison's Fotopic site of TC1 outside the Loco Works in chocolate and cream here. Look under '35mm slide scans' at the RH middle of the second page. |

Renumbered
DB999500 and now in maroon livery the vehicle later became Test Car 2
when transferred to the DM&EE at the RTC. It is not certain but it was
probably re-painted into the red and blue livery of the departmental
test vehicles and re-numbered ADB999500. It had an unfortunate demise in an accident on the Crewe - Winsford slip brake testing work in the mid-1970's when the vehicle under test failed to stop and collided with the Test Car at low speed. Fortunately nobody was seriously injured, just shaken but the vehicle suffered irreparable damage. It was dumped at Crewe Coal yard for a number of months before being cut up on site. |

The later Mk3
version of Test Car 4 behind a class 47 at the test track in 1999. This

became DM&EE's Test Car 4.

The first Test Car 5 was converted from a BSK and numbered ADB975051. It is pictured in the loop at the top of the RTC yard when new on 22nd December 1972. It is still in existence at Peak Rail in Rowsley where it was moved in May 2007. However it has had a hard life, since being disposed of by the DM&EE, having all its windows welded up and was used for a long time in the Crewe Works test train fleet. See here for a recent photo |

The overhead line test vehicle MENTOR ADB975071, which was normally based St Andrew's Wharf, Derby, near the CM&EE offices at Nelson Street, was operated by the Testing Section for a while in the mid 1980's |

Former LMR overhead line test vehicle 'MENTOR' at St Pancras in the early 1980's when testing the BedPan electrification scheme. Note that it belongs to the CM&EE (London Midland Regional Engineers based at Nelson Street, Derby) and not DM&EE but is classified as Test Car 3. There had been a Test Car 3 in the DM&EE's fleet in the form of the ex-LMS dynamometer car M45039 but by this time it had been decommissioned. This designation was only short-lived as far as I remember. |
