So as some of you may know, a lot of the routes in TSW 2 have trains going through a portal after reaching the last stop. What I am suggesting is for future routes (and maybe have an update for previous routes) to have trains go back the other direction down the line. Yes, this would be unrealistic for some routes, but it would give players the ability to go back and forth along a line without either giving up their service, or going back to the main menu to select a new one.
I posted this (see below) about the same topic in a different thread, but its as worth saying there as it is here.
