I'm doing research on trains and Google isn't helping, it's giving me everything but what I need so maybe I'm not posing/wording the question properly or something but a friend told me about this so hopefully I can find the answer.
I believe it is 6 gallons per mile. I can tell you that a tractor trailer gets 4-8 miles per gallon of diesel.
Almost all diesel's are a electric hybrid. They were first developed in the 1920's. The diesel motor drives a generator which drives the electric motors in the locos axles. This of course was done because the is NO transmission available that can handle the amount of power these engines can make. Generally (depending on the loco) they'll burn anywhere from .5 gpm for the smaller locos to 10 gallons per mile for a large 6600hp loco fully loaded.
