A broadside picture of L420 (51400, 59510 & 51358) as it slows down for the Culham station stop on 26 May 1992, whilst working the 2C66 17:35 Reading to Bicester Town Network SouthEast service. After working stopping services in the Thames Valley for over three decades, the reign of Class 117s was rapidly coming to an end when this picture was taken. L420 would move away from the area shortly afterwards, and like a lot of the Reading allocated sets, would be reduced to a two car unit for its final years in traffic.
