The ALco T-6

The Alco T6 was a diesel-electric locomotive of the switcher type rated at 1,000 horsepower, that rode on two-axle trucks, having a B-B wheel arrangement. The 'T' stood for 'Transfer', meaning this locomotive was capable of faster transition and higher sustained speeds than the regular 'S' - type yard switcher series. ALco ( American locomotive company ) unfortunately went out of business in the 1960's.
