Rolling Line, one of the better train-set simulators available for VR right now. I do reinforce though that it is a Train-Set Simulator, not a Train Simulator. The controls were also crafted in hell but workable once you get used to them. 

Also available as an alternative is "Locomancer", which is another Train-Set Simulator but focuses more on the multiplayer aspects of it, getting together with some friends to lay some track. Both games do however allow you to assume direct control of a locomotive.
