Someone recently made a post about this, but I slightly disagree with their route choice. That person said there should be the Hudson Line. I disagree as this line is not the most used nor the most interesting and fun to drive. I would say the best route(s) to do would be the New Haven Line with the Danbury and maybe the New Canaan branches. The DLC would be US$20-30 and include the M7 (repainted from the LIRR route) and the M8 which is just a slightly modified version operated by Metro North which would not be that challenging to make. One of the stations on this route is already included in the game with NEC New York (New Rochelle), so that model could be ported over. Grand Central Terminal would have to be created which would be very interesting to see and I feel this route is justified as a lot of the assets and mechanics for it have already been created in NEC New York and Long Island Rail Road. Thanks for reading, and if you are a Dovetail employee.... THANK YOU AND PLEASE PRESENT THIS TO MANAGEMENT!
