ATHEARN EMD GP49 DIESEL LOCOMOTIVE PROTOTYPE AND BACKGROUND INFO:

Sensitivity to fuel economy in the 1970's justified the GP39-2 in EMD's catalog. It also laid the ground work for EMD to start exploring locomotive designs that utilize engines with larger piston displacement yet posess fewer cylinders. This approach has become the foundation to modern locomotive technology.

In 1983, EMD took this concept to the next step by introducing the GP49. Basically a 12-cylinder version of the GP50, it produced almost as much power as the 16-cylinder GP40-2, with supposedly better fuel economy. The model was not a huge success, with only 9 being sold in the open market, as well as 6 GP39Xs being upgraded to GP49 standards. Interestingly, an SD49 was also cataloged but generated no orders.

Boston & Maine was an esteemed Class I carrier based in New England. At one time, they operated an extensive network in New York, Vermont, New Hampshire, Massachusetts, and Maine. They became part of Guilford Transportation Industries in 1983. What if an independent BM had survived a bit longer to order new power from EMD, in the form of GP49s? Here’s our take on what they would have looked like.
