54340 leads a lengthy DMU formation at speed (well, 75mph!) past the Great Northern Railway somersault signal (long since removed) at Havenhouse on 14 June 1986. It is working the 12:40 Skegness to Derby Saturdays only service, which was a real express service, stopping only at Boston and Nottingham. 54340 was withdrawn in April 1991 and cut up almost immediately.
