So you don't want advice on how to get a
killer ticket combination to
let u go to
ATB on the
9pm departure with a requirement to
don't stop at intermediate stations after all?
In that case, it depends on which service you want.
Splitting at Melton Mowbray would save about £10 .
Ely would save about £5, which I think is on all the routes.
Melton Mowbray is a good place to split when taking that route but yes, it is limiting, especially now that the Liverpool services don't call Nuneaton, so he'd end up on LM stoppers to interchange with the XC service.
Only the Norwich - Cambridge services call at Attleborough so a direct EMT service is not possible, but if you were using the direct EMT service to somewhere like Thetford then changing, I'd look at splitting at places like Manchester, Sheffield, Peterborough...
It's probably quickest to go via London, strangely there is no through ticket but splitting somewhere like Norwich would solve that. It's certainly not the cheapest. But it avoids pathetic 2-car overcrowded poxy trains though (well, except for the Norwich-Attleborough leg obviously)
