Here's one example I spotted - looks like it's taking quite a long time to turn them round at Finsbury Park, given the station probably isn't really cut out for that sort of thing!

Is Alexandra Palace even large enough to disembark a full-size East Coast train Tom?
The 1230 to Edinburgh has just set off 151 mins late.
Looks like a complete fiasco whether you are on a train or not, I bet train crews turning up don't know what is going on either, that's if even they can get into the station.
East Coast are only tweeting two types of standard messages, which are causing people to get even more annoyed.
One being that they are running a revised service with trains terminating at Finsbury Park, to which umpteen people rage back at saying that they can't get into said station either on foot or by train.
The other one being that if they are delayed by over 30 mins they can claim delay repay, to which everyone rages back how they demand compensation because they've just spent hours stood in the cold, stood in a subway, wedged on a stationary train under someone's armpit etc etc.
