hi everybody, down here ,down under we have the model CV40-9i (my avatar photo) locomotives built by goninan/ge with variable horsepower of 2850,3560 and 4020hp in an effort to reduce fuel consumption and emmisions on trains not requiring the full 4000hp,but my question is this,if you say take a c36-7 and a c30-7 the starting tractive effort is still the same as the adhesion level at low speeds is also the same, i am wondering what real benefits are say pulling a 3000t train at 35mph with the lower hp settings than rather the full 4020hp on the same train at the same speed?.my point is, would'nt the loco at 4000 odd hp be using less throttle to pull the train at the same speed compared to the same loco on same train using a lower hp rating? or am i out of my league here?(anyone,anyone?) thanks, dash7
