This is certainly a bit of a novelty. A hybrid Class 150 unit comprising one car from each of the production series subclasses (150/1 without front end corridor connection and 150/2 with corridor connection). 52129 of set 150129 leads a coach from set 150253 past Bramshall on 12 August 1989 with the 13:40 Crew to Derby Provincial Railways service. Note the variation in livery between the two subclasses with the switching around of the light and dark blue colour stripes.
