What is the ratio of fuel consumption between cruise and acceleration?

Question by sparc77: What is the ratio of fuel consumption between cruise and acceleration?
I realized locomotives burn more fuel when accelerating than when they have the train up to speed and cruising. But what is the ratio?
Granted there are a number of factors involved such as number of cars per locomotive, load weight, final velocity, incline and so forth. I not trying to get too specific, just looking for an educated estimate.
