I have to admit that I think the gates should be able to open and close, after that you also need a public transport card in our country we call it OV it means openbaar vervoer
I think being able to operate a train realistically, walk on the tracks and do so much more is already aiding trespassing if you ask me...
At the moment, the game lacks the stability required for new features like that. They should prioritize resolving the existing performance issues first.
