A bit of confusion in numbering at Ayr, SC52012 is without doubt a Derby built Class 107 DMCL carriage so why does it carry set number 101366? Records suggest that during 1985 52012 was coupled with Class 104 coaches 59215 and 53577. The 3 car set appears to have reds up so it is hoped that it was moving onto Ayr shed, 14/7/87. ©John Chalcraft/Rail Photoprints
