OpenRails and A&M

I recently installed the latest version of OR on my system. I just tried running the A&M, West Haul 2 and had quite a surprise. I realize the loads of rock to be picked up at the Junction are heavy but, I can't even push them back up the branch to hook up with the grain empties. Is the physics that different in OR? If so, is there a way for a person, who isn't comfortable getting into the program, to adjust the settings? Or, should I just modify the activity to run with three engines?
Hey Bill - If I remember right, the physics on OR are only general and not "tuned" yet.

What's different between the two?
First, OR uses the actual Davis equations for friction (i.e. resistance), not necessarily the Friction definition in the ENG file. This may make the train easier or harder to pull compared to MSTS depending on how accuarate the parameters in the Friction section are.
Two, the tractive effort and adhesion are accurately calculated, including wheel slip. check out the youtube vid: http://www.youtube.c...mp;feature=plcp
Third, OpenRails simulates the "loading" of a diesel electric locomotive, rather than the physics performance of an automobile, which MSTS better resembles.
As OpenRails introduces new parameters, this will make OpenRails physics even more accurate including traction motor temp degrading, tractive effort curves, phase transition for first generation diesels, parallel & series motor simulation and much more.
I have A&M, it's one of the core test routes for the OR team. Will give this activity a try over the weekend and report my results

Yes, please do.
