 Both horns were relocated to the front of the cab, although the rebuilt DG 760 had three - two forward facing on the cab front, with one behind the cab.DG 760 was released from Hillside in August 1978 and was placed into service as the first of an eventual ten rebuilds to be completed between 1978 and the end of the program in 1980.While the railway unions - the Locomotive Engineers Association and the EFCA - were pleased with the cab design which took into consideration their input from the early design phases, the locomotive was not as mechanically successful as it should have been.
