On Train Sim World, Great Western Adventure, there are many information display boards, and all of them are blank. It would be a nice feature if they actually displayed when the next train is or something like that. And even the displays on the trains themselves, they're blank, with no announcements, that would also be a nice bonus.
What about window labels for the HSTs? When you're in passenger mode at Paddington itsi difficult to know which HST is on which service.
