It's guaranteed to be an HST.
The 166s do not currently operate beyond Didcot ( except north to Oxford ) and Bedwyn.
That's interesting - are they running through via the B&H ( am I right in thinking the blockade is the Swindon line? ) or just doing shuttles between Bristol and Westbury?
No. The Blockade is at Reading, major diversions and which have been well publicised in one way or another on the Forum
There's probably more than one thread, but here is one: FGW HST diversions via High Wycombe and SWML, Easter 2015Yeah, I'll try to find the thread again - I saw it by headline the other day but as I'm not planning to travel in the area over the relevant period I didn't really study it...
Weekend First should be available, £15.tomorrow I'm going on the 9:00 from paddington to bath, will it certainly be a hst? Or will it be a 166? Just making sure. If it's not a hst I'll be a little disappointed but whatever.![]()
