Class 55 Deltics

Named after the Napier Deltic diesel engines that powered them, the Class 55 Deltic locomotives served on Britain's railways from the early 1960s until the last examples were retired at the beginning of 1982. While in service, the Deltics dominated services on the East Coast Main Line between London Kings Cross and Edinburgh and Aberdeen. Six are now in preservation.

Obsessed by the Deltics since his childhood, Colin Alexander has photographed these charismatic locomotives in mainline service, in withdrawal and in preservation since the 1970s. His pictures make a wonderful personal record of the Class 55 locomotives, the Deltics.
