Class 45 No. 45001 at Wakefield Kirkgate in the early 1970s. Built at Derby in November 1960 as D13 and one of the first diesels to receive TOPS numbers in April 1973. Here the headcode box is still being used so it is before January 1976 and I suspect 1973 or 1974. Withdrawn in January 1986. Photo: Steve Armitage.
