British Rail Class D3/5 was a shunting locomotive built by British Rail at their Darlington Works in England. It was a diesel powered locomotive in the pre-TOPS period and the class was numbered 13152–13166 (later renumbered D3152-D3166).
They were similar to Class D3/4 (TOPS Class 10, numbers 13137–13151 / D3137–D3151), but had electrical equipment from British Thomson-Houston rather than GEC. All fifteen locomotives were withdrawn between February and December 1967.
