I have read that TSW2 will be capable of running steam in the future, is this true and if so when might it be available?
It's a vague answer, DTG said that they have the foundations with the Simugraph engine to the point where it can support 'Steam' locomotives to their expectations, however, this is still heavily in development and probs will take more time to develop. I'm guessing it will be a bit of time before steam comes, no earlier than mid-late 2021.
