My son and his friend travelled from Hull to Newcastle, changing at York. The vdu display at York said the train would leave from platform seven but it actually left from platform eleven and they had to get a later train at additional cost. How can the information board be wrong ?|||The displays are all fed off the same computer system that monitors trains across the network. By default, the system will usually display the platform the train is scheduled to depart from, which is the same every day for each train. Sometimes, however, for various reasons such as a delayed train (or another preceeding train running late), the signalling staff will change the train to a different platform. 99.99999% of the time, the system will know about this, and will update the screen. Depending on the system installed at the station, the computer may annouce the change audibly too. I'd suggest that perhaps the platform change was a last-minute thing, and happened after they last checked the screen. The moral of the story - keep checking the screens. If it gets to a minute or so before your train is due to leave and it still hasn't arrived, don't just stand around wondering what's going on, go and check the screen!|||I believe the VDUs are computer controlled, with information programmed in, as each days services follow an indentical pattern. However, sometimes for operating reasons, the departure platform is changed - maybe the correct one is occupied by a late running service or failed train. No one then bother to override the departure display VDUs. However, on large stations like York (and I have used it on very many occasions myself), a loudspeaker announcement is made of the platform alteration, and this will be done several times. It always pays to listen!|||I had the same problem recently at Bristol Temple Meads. I wanted to get on a train to Bath, I watched the VDU, got on what I thought was the right train and ended up heading for Gloucester. Most of the time the system works OK, but sometimes mistakes get made. I can only assume this is because code numbers for each train have to be input and occasionally people get it wrong.|||some one pushed the wrong button. Friend of mine works for a railway company, he says they do it in error, not often but it happens
