Meeting on public display networks

Sunday night I travelled to Lugano for a meeting public display networks. I figured out that going there by night train is the best option - leaving midnight in Karlsruhe and arriving at 6am there. As I planned to sleep all the time my assumption was that the felt travel time would be zero. Made my plan without the rail company… the train was 2 hours late and I walked up and down for 2 hours in Karlsruhe at the track - and interestingly the problem would have been less annoying if public displays would provide the relevant information … The most annoying thing was passengers had no information if or when the train will come and no one could tell (neither was anyone at the station nor was anyone taking calls at the hotline).
The public display - really nice state of the art hardware - showed for 1 hour nothing and that it showed that the train is one hour late (was already more than 1 hour after the scheduled time) and finally the train arrived 2 hours late (the display still showing 1 hour delay). How hard can it be to provide this information? It seems with current approaches it is too hard…

On my way back I could observe a further example of short comings with content on public display. In the bus office they had a really nice 40-50 inch screen showing teletext of the departure. The problem was it was the teletext for the evening as the staff has to manually switch the pages. Here too it is very clear the information is available but current delivery systems are not well integrated.

In summary it is really a pity how poorly the public display infrastructures are used. It seems there are a lot of advances in the hardware but little on the content delivery, software and system side.
