More details and accident report at http://www.railwaysarchive.co.uk/eventsummary.php?eventID=6364.
circa 1970 - Unknown, LMR
Collision involving Class 108
Class 108 DMBS M51921 was withdrawn for an unknown reason in October 1970.
Sanding down the drivers side of DMBS 51941 during a repaint in 2002 the first blue livery had the correct number. However further sanding revealed another set of white vinyl numbers but these comprised 51921. Further sanding found green paint next, again with 51921, and then another green layer with 51921.
It appears the drivers side was rebuilt using parts from 51921 - possibly much of the bodyside. On the bufferbeam of 51941 there were two large welds on the inside of the drivers-side buffers. Further sanding of the bodyside revealed that there had been extensive replacement of lower panels on the drivers side (there was only blue paint - no green underneath). It also carried a builders plate for lot 30660 (a DMC) on that side.
It may be that the two vehicles were in a sideswipe together and one good vehicle made from two? Any further information would be welcome.
