Lionel models of the Baldwin Locomotive Works' DR-12-8-1500/2 diesel-electric, known colloquially as the centipede, Baldwin's first road service diesel. The model designation came from Diesel Road locomotive, with 12 axles, 8 of which were powered with traction motors, and two prime mover engines of 1,500 horsepower each.
The Pennsylvania Railroad bought 24 and the other purchasers were the National Railways of Mexico (Ferrocarriles Nacionales de México) and the Seaboard Air Line (14 each). They were not considered very reliable, and were eventually power-derated and used as helpers. None survive today.
