Hi!

I am looking for information that helps me to design rail systems underground, locomotive weight and other things for tunnel rails, 36 inch or 42 inch track gauge. I am also looking for a formula that helps me to calculate the braking force and stopping distance of a train.

Thank you very much for your help!!!

Yours, Andreas
