Looks like two different trains will hit each other when they go through the bridge at same time once the UPS go lower like 30-40, not sure this is normal bcs UPS is not enough so they cann't work perfectly or just a bug?
yes, sure, how to send my save? i have 1k robot with me, and once two trains go through the bridge, will have one or two robot carry the repair tool go out to follow the trains, i guess that's they hit each other and robot want to go to repair them.
