British Rail Class D16/2
British Railways Class D16/2 was a class of prototype diesel locomotive built by BR at Ashford Works and introduced in 1950–1951, with a third example being introduced in 1954. They had been designed by Oliver Bulleid for the Southern Railway before the 1948 nationalisation but did not appear until after nationalisation. The diesel engine and transmission were supplied by the English Electric company but the Bulleid influence was obvious. The box-like body style closely resembled Bulleid's electric locomotives and was quite different from the usual English Electric style, typified by British Rail Class D16/1.
