Looking startlingly different in light green undercoat, 50015 Valiant approaches Irwell Vale on 18 June 1995, en-route from Rawtenstall to Bury, during the East Lancashire Railway's Diesel Gala. As I had missed 50035 Ark Royal's famous mainline outing in grey undercoat, when it returned from Doncaster to the Western Region at the head of a service train in 1986, I wasn't going to miss the opportunity to get a picture of at least one Class 50 in this unconventional 'livery'!
