I'm having some issues with certain steam locomotives I have installed. The stability issues I'm experiencing are not game stability issues, but rather stability of the locomotives themselves. More than a few of my Britkits locomotives refuse to stay stable on the track above seemingly random speeds. They will jump around randomly and then eventually derail. This also happens with a lot of the MSTS conversion locomotives.
I don't know what's causing these issues and would really like to fix them. I know how to open .bin files, I just don't know what to do from there to fix this. I would really like to be able to run my Mountains a little bit faster than just 50 mph or whatever the game decides it wants to derail at. Any help is much appreciated.
