50008 Thunderer passes Lympsham on 25 April 1990 with the 6C55 14:37 Bristol East Depot to Exeter Riverside departmental working, on this occasion it is hauling a Plasser & Theurer RM 62 Ballast Cleaner (all now scrapped), rather than the usual rake of ballast hoppers. Thunderer spent the whole of 1990 allocated to the DCWA engineer's pool, but with very limited information about its day to day workings, it was difficult getting many pictures.
