In the last rays of the setting sun, 117724 (51333 & 51375) arrives at Ridgmont with the 18:40 Bedford to Bletchley service on 4 June 1997. Formerly Thames Valley set L401, it was ousted from its Paddington duties by the arrival of the Class 165 Turbos in 1992. AT this point it lost its centre trailer and was renumbered 724. At the very end of its career, it was obviously decided to incorporate the class designation in the number, in a similar way to the units that had moved to the Provincial sector, therefore becoming 117724.
