I would like to ask the developers to look into the derailment checking algorithm, because since the release of the steam locos I got around 10 derailments on multiple tracks where I was way below the allowed speed at that section (mostly on the Rush Hour Dresden line). This is very annoying since I have to start the scenario again (save is turned off due to the massive stutter when a train arrives at a station and the game saves the state). I don't know whether you changed anything in the derailment checks but these are too many issues, before the steam loco release I had absolutely no derailments.
It's an issue with coupling (or buffers). They way they work has been changed on the entire game since SoS released, this caused jerky trains and derailments on a huge number of routes and DLC.
You can do it in the Engine.ini file under TrainSimWorld2\Saved\Config\WindowsNoEditor. Just add these lines at the end before starting the game: [/script/engine.renderersettings] ts2.save.CheckpointsEnabled=0
