One of the main downsides to a Diesel-Electric Locomotive is the Diesel Prime Mover doesn't accelerate or rev up as quickly as it would in a car or a truck, and so the power output from the generator is not as nice while it revs up as it would be in a purely electric locomotive.
Note: the 66 GO MPI MP40-3C locomotives have an EMD 710GB 16 cylinder diesel prime mover and a Caterpillar C-27 diesel engine for the Head-End Power generator. the 1(+16 on order) GO MPI MP54AC have 2 16-cylinder Cummins QSK60 EPA Tier 4 engines as prime movers and HEP generators.
