A Class 114 DMU is seen at Firsby, Lincolnshire, around 1970. With the destination blind reading Peterborough, it is possibly a service that originated at Grimsby, which would travel to Peterborough via Boston. Firsby was closed on 5th October 1970, along with much of the east Lincolnshire network. Graeme Phillips Collection.
