Having run a railway station where the monitors kept going down, they have my sympathy!
At least they should still be able to provide the correct information tough . We had a system which was designed to provide information to old-style CRT monitors but which was used to feed modern digital ones. That meant that they had to use software to change a stream of black or white dots into words and letters. However the software was far from perfect, with trains to Norwich often shown on the monitors as going Harwich (and vice versa) because the system couldn't read the information correctly.
To make things worse, test data which had been used when the system was first designed had a nasty habit of suddenly showing up on the monitors. So there might be a few lines of valid information about train departures followed by something like "The third grommet on the left is harassing a purple gnome sideways in Transylvania".
