Taking King’s Cross as the example it’s actually really time consuming when you’re up against it time wise to come off the tube walk up the concourse to see the train (which will be on the furthest left screen, the one furthest away from the ground floor platform access point) to then walk back again, perhaps through a thousand people to get to the train. Unless your train is likely to go from 9+ you’re just as well going through the barrier and looking at the displays on the end of each platform as you walk across them.
That does bug me. It makes sense at stations such as Leeds with a long, end-on gate line, but I always felt that the screens over the gates should run left to right, with the next departures on the right. Walk in, look up; not walk in, walk a bit further in, look up, walk back the way you came.
What bit of “departure time” do people struggle with? It is when it departs!
Is that 13.00:00 or 13.00:59? You'd miss it at the former and catch it at the latter. WTT departures are usually listed in quarter minutes.
Not displaying platforms on the screens at Kings Cross until ten minutes before departure also causes problems when there is a massive rush for the gateline at exactly the time it shows. So you have around 7 minutes to get the platform from the time it it shows on the screen until the time it disappears for ever.. I always thought the system at KX where everybody waits in the main concourse staring at the departure boards rather than a steady trickle through the barriers to the platforms a little strange.
In fairness, it's often longer than 10 minutes; it depends on the departures. Sometimes they want Stevenage and Peterborough passengers to not catch the Leeds train if it's busy. The Leeds train platform is always called after Edinburgh one if they both stop at Doncaster. We could do with an audible signal when the boards change though, similar to the old split-flap displays, instead of milling around staring at the screens. But I've turned up 20 minutes early for my train, and the platform has been called.
As a proportion vanishingly few passengers use RTT, it's really only rail enthusiasts and staff who even know it exists.
No-one I know uses RTT or similar. Mostly they ask me (because they know I do).
At Euston dozens of peoples gather at the top of the platform before it's announced on the boards, [snip]
At KX, Standard passengers use the first floor/mezzanine level where the food is and line up along the balcony looking at the set of boards near the Harry Potter Money Pit. Handy, if you know you're in coach A to G. They're not app users though, they're just regulars who know how KX works.
Have to be honest; I'm fine with three minutes, just as I was with two minutes. I suspect it's to ensure that LNER leave the station "on time". At Leeds, if the xx11 XC service is late departing, the xx15 LNER will still leave on time (and release the platform). It will then stand just beyond the signals at Leeds West while the XC service runs three minutes ahead.
