The Alco T6 (DL 440) was a diesel-electric locomotive of the switcher type rated at 1,000 horsepower (750 kW), 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.


The Delaware Coast Line Railway, the Ohio Central Railway and the Arkansas & Missouri operate the T-6. Ohio Central's T-6 is unique because it was the only one built with Hi-Ad trucks. 14 T-6's survive in all.
