Twist is right... N-S or E-W not much difference. But a perfectly flat track , a straight line, would not be level. It would rise from the middle to each end. The carriage would roll from the ends to the middle point. Picture a tangental line to a circle.... A level line would follow the curvature of the earth...and wouldn't be straight LOL Philip. ----- Original Message ----- From: "Gary L.

Assuming a perfectly flat track, the train should not move at all. But I'm feeling a twist coming....
