The short answer(I'm sure that the professional railroaders who post here can explain this better). <br /> Remember,when talking about modern locomotives,your dealing with a Diesel ELECTRIC system. The Engine turns a generator(nowadays more likely an alternator)which generates current which then is used to power the electric traction motors powering the axles. But that's an oversimplification,as you have a complex electrical transmission system which regulates the power. This is complicated in a DC traction motor(which most commonly take the AC current from the alternator and rectify it to DC) and even more so in the newer AC traction motor units(which actually take AC,rectify to DC,then phase invert it back to AC). So an engines time to load refers to the interaction between the prime mover and electrical system. <br /> Most industry sources that I've read support the idea that two cycle diesels(EMD 710,645,567 series)offer superior loading at low speeds than four cycle engines(EMD 265-H and all GE's).
