Baldwin DR-12-8-1500/2

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. Its designation means a diesel road locomotive with twelve axles, eight of them driven, and two engines of 1,500 horsepower each, on trucks arranged 2-D+D-2. Built between December 1945 and July 1948 in the Babyface style, it followed steam and electric practice, with a carbody on two articulated cast steel half-frames. Orders came from the Pennsylvania Railroad, the Seaboard Air Line Railroad and the National Railways of Mexico, but reliability was a continuing problem and the design was effectively obsolete against EMD. Most Pennsylvania and Seaboard units were scrapped by the early 1960s.
