What is the Best Method for Calculating Rolling Resistance in Train Carriage?

[QUOTE="scottdave, post: 5857187, member: 618222"] The way that I recall, the rolling resistance comes from the tire slightly deforming while in contact with the surface. I think the resistance that you want is from the wheel bearings, not the friction between the wheel and track. I think it will be much less than 0.5 I base this on the fact that I can put my 3000 pound vehicle in neutral on a level surface, and be able to push it. I'm guessing that I'm not exerting a lot more than 100 pounds force. If the wheel starts sliding in relation to the track, then you are loosing power. The goal is to have a high enough static friction (between wheel and track) so that it does not slide. [/QUOTE]
