what is it?
The Alco T6 (DL 440) is a diesel-electric switcher locomotive rated at 1,000 horsepower (750 kW), that rides on two-axle trucks, having a B-B wheel arrangement. The 'T' stands for 'Transfer', meaning this locomotive is capable of faster transition and higher sustained speeds than the regular 'S' - type yard switcher series. A major difference underlying this shift is the use of the heavier GE 752 traction motors, as used on road locomotives, in place of the GE 731 traction motors used on nearly all Alco's preceding switchers.
