AC44C6M Diesel Locomotive

Prototype Information

The AC44C6M is a rebuilt locomotive developed by GE and Wabtec. It converts older GE Dash 9-40C/CW units from DC to AC traction. Norfolk Southern began the program in 2015 to extend the life and performance of its aging fleet. The rebuild includes a new wide-nose cab, upgraded electronics, and AC traction motors. Other railroads, like Canadian Pacific and BNSF, later adopted similar rebuilds. The AC44C6M offers better tractive effort, reliability, and fuel efficiency compared to the original units.
