Indeed, and anyone who is actually going to Southampton and has purchased a ticket will be aware that there is more than one route, and fare, available. Real Passengers (rather than pedantic trainspotters) will know they are expecting to catch a train that says Southampton on the front of it from a specific platform at a specific time, even if their actual destination is one of the many stations the train calls at on the way there. The real value of the display is to confirm the expected platform and departure time of the train. There aren't examples in the pictures that have been posted but I'm pretty certain delays, cancellations and platform changes (rare, but they can and do happen) would appear there.
I don't think that's the way the displays are intended to be used.
Firstly, they show a wide array of intermediate stops, not just places that are the ultimate destination of a service.
Secondly, if you are looking for the train that stops at your station, with ultimate destination of X, then information on the next
fastest train to the ultimate destination is not really useful to you.
Seems pretty clear that the intention of these displays is: you are wanting to go to X, you find X on the board and it tells you which platform & train to head for, in order to get to your destination ASAP. For anyone using the displays in that way, being directed to a train that will get you to your destination 2 hours later than you otherwise could have, is actively harmful.
it appears now that people have the expectation for information to be provided without them doing anything. To me that is a sad state of affairs. Mini rant done!
People have the expectation for accurate, not misleading, information to be provided. If it's not possible to do this in the space available on the boards, then just don't show it, and people will ask someone or use a journey planner on their phone.
I don't see why it's in any way controversial to point out that a public information display is likely to cause people to make a bad decision through no fault of their own.
