@WerySkok yes but infmap bypasses those limits by implementing its own coordinate system and (world) collision. The map in the video is https://steamcommunity.com/sharedfiles/filedetails/?id=2917249160&searchtext=infmap+metro which is endleslly repeating straight line. I've had a server running it with an E(zh(3)) 5-car consist for weeks just going forward and it didn't crash nor derail. 6-car consists consistently derail tho. Only two bugs is that lights and sounds aren't properly hidden in infmap
