The Alco 539T was a
An eight-cylinder inline version of the 539T was developed by Alco. This diesel engine developed from 1,080 to 1,300 horsepower (810 to 970 kW). It was never used in a locomotive, but a twin bank V8 had been planned to be used in an early version of the “Black Maria”
The 539 engine was developed in response to the perceived drawback that Alco's line of diesel switchers had a restricted field of vision because of the high hood. Both Baldwin and EMC were offering diesel switchers with a lower engine hood that the trainmen could see over. The 539 engine was developed from the 538 engine, both had the same cylinder dimensions. The engine base of the 538 was flat and rode on a flat underframe. The change that the 539 offered was to lower the base of the engine into the frame. This was done with revised mounting lugs and a modified oil pan. The modified 538 became known as the 539 and the change allowed the engine hood to be lowered by 27 inches (69 cm).
