Although there were a number of Class 50s allocated to the DCWA engineer's pool during 1989 and 1990, occasionally other locos were also employed on mundane departmental workings, especially at weekends. Such was the case on Sunday 29 October 1989, when 50026 Indomitable found itself in charge of a London bound ballast rain, seen here running along the up relief line at Shottesbrooke. The tatty Network SouthEast liveried loco had spent the previous few weeks working Waterloo to Exeter trains, but after its weekend's use on ballast duties, then spent the rest of the year working passenger trains out of Paddington.
