A bizarre spectacle at Radley on 19 April 2013. Fresh from a repaint into two different interpretations of London Underground livery, 20227 & 20189 pass through the station with the 0Z20 12:27 Butterley MRC to West Ruislip light engine move. I very rarely bother to photograph light engines, but the sheer novelty of the livery, and the rarity of Class 20s at Radley, made this worthwhile. I was already at Radley to photograph 56303 on the Didcot to Calvert flyash, so it was no hardship to wait a few minutes for this burst of colour.
