I have just booked advance tickets for the 20th May, on the 11.00 London-Norwich and 17.00 Norwich-London, to see what the service is like and how it runs? I know it risky and could well go wonky on the day but for 20 return its worth the punt, i noticed one thing and worth noting if anyone else going for this train, there are no allocated reserved seats on these trains, so looks like free for all, the inside looks nice and smart from YouTube videos I’ve seen, i wouldn’t be surprised if there bit of fanfare and maybe some top bods on the service, could be fun.
I've done the same.
No seat reservations. No normal first class fares but there is a business ticket that I assume will be first class.
