Sorry, me again! I'm guessing there is a simple tick box somewhere that stops the track from laying under the ground. I'm just playing with a straight bit of track on an embankment but always sinks through. I'm assuming there is a collision setting somewhere but again, the tutorial video doesn't explain this. Thank you
Mentioned this is the guide I did as it was something that happened to me Delete the piece of track in network edit mode then go back into Route Building mode, right-click your terrain, and select Regenerate Landscape Collision Components". and select Save all too
