A colourful sight on a gloomy summer evening! Harry Needle's bright orange 20314 & 20311 lead the 7X09 15:54 Derby Litchurch Lane to Amersham S Stock underground unit move past Shrewley on 10 July 2013. 20142 & 20189 are bringing up the rear. It is not easy to hear them coming at this spot, due to the close proximity of the M40 motorway!
