Is this a particular problem on Network Rail stations? If so, what are the channels of complaint/consultation to get them to do something about it?
I suspect ir relates to bigger stations in general, which will correlate to Network Rail stations.
There are far more trains running in most places than at any time in the past, and in places screen / dynamic display real estate has shrunk. Result - too much data to display easily in a single go. Further, with so much connectional traffic and the connections often being quite quick, siting becomes none-obvious.
