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.

[edit] Operation
The original locomotives, numbered 10201 and 10202, worked services on the Southern Region of British Railways. They were transferred to Camden depot in the London Midland Region in April 1955.
Number 10203 was outshopped from Brighton works in March 1954, its modified engine giving a power output of 2,000 hp. It was trialled on the Southern Region before joining its sisters on the London Midland, being allocated to Willesden depot.
All three locomotives were non-standard with regards to spare parts and servicing and they were withdrawn at the end of 1963. They were scrapped at Cashmore's at Great Bridge in 1968.
