I am seeing Advance Singles at £34.90 for a midweek day in Feb on the Chiltern website. Any of the Train Operating Companies should have the same fares

No need to use third party sellers

Don't understand reference to pass

Have you looked at http://www.seat61.com for information on rail travel in UK

If first train delay causes missed connection then you get the next available. It may be a good idea to get dlay noted on ticket by staff on train or at Peterborough where you change

Trying for the first Tuesday in April, for which tickets are on sale, the cheapest split I can see is:

LNER Advance Single York to Peterborough - £13.50

EMR Adv. Sgl. Peterborough to Norwich - £9

Total: £22.50 per adult, with no railcards

And you can book that yourself without booking fees if you use a Train Operating Company website and put in a via point of Peterborough, as that should force the booking engine to offer the fares I've listed.

You may need to wait perhaps a week or so for Advances for dates in mid-April to be on sale though, seems to be only up to the 1st week in April currently.

Thank you WarwickshireLad & Wex Cel

I was concerned that if I don't have a through ticket and the first train is delayed we'd have to shell out for new tickets - unless I can find a friendly guard or book a longer transfer. I don't know how well UK trains can be relied on for keeping to their timetables.

I would prefer booking direct with no booking fees. And I should have called the 'pass' a 'rail card'.

Thank you both again for your advice.

Not at all. Your intended journey is what counts.

While better to book a through itinerary even with split tickets, to make sure your connections are valid, there is no requirement to do so to allow you to be rerouted if delayed on the same tickets - ie put on the next service that will get you to your destination.

Staff might insist that it is with the same operator you were booked with, but it's a grey area as to how enforceable that is if it would delay you significantly further. (This is one of the rare instances in railway law where the still applicable European law is more generous than the UK one.)

The key thing with split tickets, is that the trains you are on must stop at the stations that you 'split' your tickets at. There are split ticketing website that will help you with this.

Yes, that is definitely an important 'rule'.

Obviously if using a split ticketing website, it will sort that for you. If doing it yourself you need to be careful about the combinations you use and whether they are valid.

don't worry about missing the second train on a slit ticket, even if using Advance tickets. If my understanding is correct this is protected under the National Rail Conditions of Carriage.
