The Baldwin DR-12-8-1500/2 (known informally as the Centipede) was the Baldwin Locomotive Works' first serious attempt at a production road diesel locomotive. The Baldwin type designation was 'DR-12-8-1500/2,' meaning Diesel Road locomotive, with 12 axles (8 of which were driven), and two engines of 1,500 horsepower (1,100 kW) each. The trucks were configured in a 2-D+D-2 wheel arrangement. The nickname came from the numerous axles set in a nearly unbroken line, much like the legs of a centipede.
