Believe it not both of these locos and the wagons are blue! Over a month's use on the Rail Head Treatment Train has taken its toll on the DRS Class 20s, as an absolutely filthy 20310 leads classmate 20311 on the 1Z63 13:35 Wymondham to Colchester RHTT as it approaches Shippea Hill station on 29 November 2006, running its customary 70 minutes early. Although apparently not so good further west, in East Anglian it was a completely sunny day with not a cloud all day.
