I would love to see the New Jersey Transit Morristown Line also known as the original Midtown Direct service from the town of Dover into NY Penn Station. The Midtown Direct service would be interesting to run in TSW because you would have to switch the engines Pantograph after Newark Broad Street station when the Morristown line joins the NEC line. Also living in the northwestern part of New Jersey near the Hackettstown, Mount Olive and Netcong stations the scenery on the western part of the route is extremely scenic. The Morristown line would allow for both electric and diesel operations as electrified track runs just a bit west of Dover with dual track running just west of Port Morris.
All these new trains in TSW, especially after third parties are coming in to the dlc development process (as well as making their own dlcs) are definitely a possibility!
Yes. Hopefully third party party route developers will speed up the process of getting more routes in the game.
