A trolley drive truck in the surface mining application is a diesel-electric drive truck that has an option installed that enables a secondary means to power the wheel motors. When activated, diesel generated power to the wheel motors is cancelled and overhead catenary power is connected and diverted to the wheel motors through the inverters.
