hello all. as you may see i am new here. i am trying to find departure boards that show live departure times for my trains and ai train too. has anyone got any suggestions that i could have a look at please?
Not possible. There's no way to access this information with the available Lua API functions. You could only do scenario-based handmade textures containing the information.
As said, it hasn't been done. The boards in the 24 hour timetables on TSW (and possibly scenarios) only work because, I suspect, they are programmed in a way that they comply with a 24 hour timetable. Because every scenario has its own unique timetable in TSC, there's no real way to be able to achieve an operating station sign board.
