Some times I can go for a few miles at say notch 2,3,or 4. Depends on the trains weight, length and track profile. It's usually a fairly constant adjustment of power and or brake to keep the train stretched or bunched or whatever the engineer feels is necessary. Even on flat ground. <br /> Now a train of all loads that long is not that hard to control. His train was approaching 7000 feet. Most likely one part of a train is going up or down a little. It mostly keeps itself stretched. Not to say he doesn't have to know what he's doing though. These guys are handling trains at the upper limits of what the braking system is designed for. I take my hat off to them. <br />But a freight train with a mix of loads and empties is a little different. Say the loads are on the rear and the unit starts up a slight grade. The head end of the train slows a little and the faster moving rear slams into it. It's refereed to as a run in. Very embarrassing, let me tell you. It's easy to avoid with all loads or empties or the loads ahead of the empties. <br />This is more information than you asked for, Jen, but it's a hard question to answer without a little 'splainen. <br />Slofr8.
