Hi,
it seems that I don't need to have rails. When I put my guy in a locomotive with FARL module, I can activate it and it will work, even if there is no cargo, or no rail available at all.
Besides, it cannot find the name of my mod rails. Both rails (normal and mod) are called "Raide". How to fix it?
Thanks

Forget the second point, I found out how to "rename" rails: Localised_name (Maybe you should add it to the information?)

FARL doesn't need rails or anything if you have cheat mode enabled. Maybe that is/was the issue?
