Who built diesel cab units?
The Electro Motive Division of General Motors built the popular E and F units. EMD dominated the diesel field. A distant second was the American Locomotive Company, or Alco. It built the beautiful PA and FA locomotives. Baldwin and Fairbanks-Morse trailed behind EMD and Alco by a huge margin. Baldwin built the Sharknoses, Babyfaces, and Centipedes. FM built the Erie units and C-Liners. Except for EMD and FM, the other companies had built steam locomotives in the past. Of the companies mentioned above, only EMD remains today.
