PROTOTYPE AND BACKGROUND INFO:

In 1949, EMD introduced the GP7. The basic design followed most diesel switchers with the addition of a short hood instead of an end-cab. The hoods were also full height to better accommodate the diesel engine and mechanical and electrical components.

In 1954 EMD upgraded the GP7 to become the 1,750 horsepowerGP9. Externally, the first GP9s were virtually unchanged from the last GP7s. Later versions would include different louver arrangements, andthe last ones would come without the frame skirting. The GP9 was available with all fuel tank, steam generator, and dynamic brake options as the GP7, including roof mounted “torpedo tube” air tanks.

Many railroads chose to rebuild their GP7s and GP9s for continued service. Often times, it was cheaper to do this rather than purchasing brand-new locomotives. Some railroads adopted a GP7R or GP7udesignation to indicate a rebuilt unit.

Morristown & Erie - GP7u

Originally built as an ATSF GP7 (#2741), this locomotive was rebuilt by the Santa Fe in Cleburne, Texas, during the 1970s. The modernization gave it an updated, chopped-nose look, new “Topeka” cab, and a new number (#2175). It was later sold to the Bangor and Aroostook in Maine, where it was renumbered to #23. Following changes in corporate ownership, the locomotive joined the Montreal, Maine and Atlantic roster under the same number, before being acquired by Morristown and Erie in 2014.

ME FEATURES:

• Non-dynamic hatch
• Three-chime horn
• Fuel tank skirts
• 1200-gallon fuel tank
• Drop steps
• MU stands
• Flat pilot
