Hello, The PIS on ECW is excellent and really adds a lot of immersion to the route. I would like to suggest adding an indicator to stations when trains are passing through which are not scheduled to stop at this station. I imagine this may be difficult to do if there is not a 'Go Via' instruction in the timetable, but assuming you have some especially clever code monkeys to do the work I think this would be a greatly appreciated addition.
Not really nice to call them monkeys, but i like the idea, that could be applied to all passenger routes! But it will probably need some more work with the timetable to work properly as you say.
