Transmission efficiency

[plainsman]

Apparently OR can now compute power at the rail from gross horsepower, but I don't know how to set the parameter in the OR .eng file? Anyone know how to set the value for transmission efficiency? It would be about 80% in a Baldwin DRS-4-4-1500 and about 94.5% in an ES44AC. Those are the extremes, most first generation units are less than 82% and modern DC units about 87-89%. AC units run above 90%. I need to know how to set the value??

Hi Bob, Long time no see round these parts.

I'm afraid the ORTS crew who might better be able to answer this question mostly hang out at Elvas Tower. Might want to ask over yonder.
