C973 (53629 & 54267) passes the barren site of Severn Tunnel Junction shed on 15 April 1991, as it slows down on the approach to the nearby station with the 2B75 11:55 Cardiff Central to Chepstow service. C973 was withdrawn the following year, and both vehicles were disposed of at Gwent Demolition, Margam, although 53629 had this fate delayed by a couple of years by becoming departmental 977820.
