Derby Works Test Train for locomotives after overhaul

The information contained in this page features to distinct subject matters:

1/ New locomotives delivered from Derby Locomotive Works would undergo a variety of tests before being placed into traffic. One of the last tests they would undergo would be a lengthy shakedown run with a rake of coaching stock, frequently making a roundtrip from Derby to the Corby area.

2/ Overhauled locomotives would also go out on shakedown run(s) before being placed back into traffic. These runs would usually add the test locomotive to a scheduled service (Derby - Leicester or Nottingham - Leicester).

The information for the years 1963 - 1964 (new deliveries) comes from the observations of Brian Webb.
The information for the years 1972 - 1980 (overhauled locomotive test runs) comes from Bill Spiby.

Other information has been found in many printed and online sources.

This is not a comprehensive list of outshopped locomotives from 1972 onwards, there were other Derby Locomotive Works employees involved in the test runs.
