To have such an iconic commuter added to the route would display some diversity and make may for other locomotives and cabs to be shown and operated on.
I definitely wanna see the M3 add to the LIRR and Hopefully in the future on the Metro North lines whenever the Metro north DLC comes to the game
The M2/M4 is currently being made for Train Simulator 20. I think the chances the M3 is coming is probably now a possibility. But cant say anything tho idk what is dovetail gonna do for TSW next.
Dude. DLC21 was added to the internal testing branch. You might need to wait for a little to see what does dovetail have in store for us.
I don't know much about the NEC (well USA trains at all) but I assume there is a local train which could be featured? I do feel LIRR and NEC are the two routes which need some more life injected into them. GWE has also been neglected but I have a feeling we won't see anything new for it now.
