It only takes a quick look at the standard of passenger information systems on even some of the older European stock for us to realise that we are a generation or two behind.
Taking German DB Class 442 units as an example they have high quality exterior dot matrix displays on the front and side, the same high quality interior dot matrix displays and then the addition of high resolution TFT panels for the display of among other things the calling pattern, realtime information about delays, realtime departure information for the next station and lots of other very useful information. The interior dot matrix displays also show the side at which the doors will open and most importantly none of the displays are used for showing superfluous and rambling information about your bags, personal belongings, calling the BTP etc. They also have clear, concise and audible announcements which provide only the information needed by the passenger.
When you compare these systems to the rubbish provided by the likes of TrainFX it shows just how much work we have to do on information provision.
