Starting in late 2015, Norfolk Southern teamed up with GE to start rebuilding some of their older Dash-9s with DC traction motors to AC traction motors. The cost was only 50%-60% that of a new AC unit. The units were designated as AC44C6Ms, and several of them at the start of the series received special paint schemes. NS 4004 is one such unit, currently on the Great Western Railroad, emptying covered hoppers.
