I have seen the term "Bozo Consists" when describing a consist that had SD45s in it mixed with older SD7 & SD9s, this was due to the IDAC slow crawl feature the SD45s and later EMDs were built with.

Andrew, I am not sure what your source of information is, but IDAC had little to do with loading coal or ore trains at very slow speeds. IDAC stand for Instantaneous Detection And Correction. It was

The basics of what you are saying are correct. However, to nitpick a little, locomotive throttle notches 1-8 are not linear. For instance on a 3000Hp SD40 notch number 4 only produces 1085Hp, about

Yeh, the early SD45s had 6 different shunt conditions in series-parallel and 4 steps of shunt in parallel! Parallel shunts could go to the same 6 steps as series-parallel _IF_ the engineer was brave

And this is exactly what my original question was all about. If the big unit is delivering half of its power and the GP7 is delivering only half of its power, aren't they going to create problems for

Bill, No, each unit will provide all of the horsepower that it can at a given throttle position. The combined horsepower of the locomotives will achieve a specific balanced speed given the train weig

Let me see if I can throw some light on this common misconception about different Hp locos MU'd together. 1. Think of a man pulling a heavy wagon with a rope. The wagon is just a little too heavy for

All motors have electrical current levels (amperage) considered safe by the manufacturer. Exceeding these levels for extended periods of time will produce serious thermal damage to the motor. DC loco
