Maybe they'll tweet it one day (like about six months after it is finished).
This reminds me of another rant I'd like to make about Finsbury Park...
The platform screens are still regularly showing trains in the wrong order, being corrected only as the train approaches. Thus, a xx58 train is shown as arriving after the xx03. It causes loads of confusion, and grief for platform staff who have to tell people not to worry (the summary departure screen is always right though).
What's odd is that while it was showing a xx58 as following the xx03, it then announced an apology for the xx58 train being delayed by 6 minutes (switching to say Estimated xx04), when I could see from TRUST that it left on time. And it did arrive on time! No delay, and not after the 03.
And, more recently, there had been some delays from Moorgate and a 6-car train to 'Letchworth G City' arrived on platform 5 instead of 6. At this time, there is a Letchworth slow train, via Hertford, due for platform 6 and a Letchworth semi-fast, via WGC, for platform 5.
Now, what happened was the announcement system told people to stand clear as the train approaching wasn't due to stop, but it was slowing down (even though it was a green signal ahead). As it gets on to the platform, it is announced as the Letchworth train via Hertford! Most rushed over, many didn't (they may think that's the Letchworth train they don't want, and I'm certain most people for the WGC one got on without realising.
I still have no faith in the new system for when it handles multiple platforms or trains that run close together.
