It's a person on a bridge just outside of Rugby station - lines closed, power off... I will divulge as know you can't and it's common knowledge now.
Serco/CS sleeper social media team at least are remaining positive - they've recently told some chap asking if he'll make his mates wedding tomorrow in the far north of Scotland that "the train is likely to depart tonight, but with delays" and "hopefully it'll make up some time". He's on the Highlander that's 3 hours late as it is with no sign of moving any time soon and it has a 92 on it.
I know the CS twitter folk can't really be saying this, but I'd be a lot less positive about the chances of it running at all and certainly him getting to where he needs to be on time - and suggest he starts at least researching other options
EDIT: person has apparently come down/been moved. So maybe CS Twitter Person's optimism was well-founded after all. Still going to be a big delay.
