I hope this changes "train" to "flight" when you apple the Passenger Information Display System to an aircraft platform and I also hope landing gears and plane sounds get supported for resource packs.
I really would like to see the vertical screens to have a version instead of 1 block wide they will be 3 blocks wide and 2 blocks height. Also something that would add a lot to me is adding railway signs that are flush to the wall or maybe making slightly rounded style and the ability to switch between styles with paintbrush
