>>1988939The Night Riviera is in Euston this weekend, as well, again as a practice for when the WCML is shut around Old Oak Common this coming Christmas. Looking at RTT (
https://www.realtimetrains.co.uk/service/gb-nr:K11265/2024-06-30/detailed) there's nothing really spectacular going on, there's just a loco dragging the coaches into Euston, presumably so they can check clearances and so on.
I wonder if Christmas is going to be a 'make do and carry on' thing, or if there's going to be a big temporary shuffle around Paddington, Euston and King's Cross
