no reservations are issued for any part of the journey... so how can I be booked on a specific train (they're advances)? If it says on the tickets, surely not all 3 trains will appear?
Do you actually have the tickets?
If so, you will see that each Advance Single ticket is marked
VALID ONLY WITH RESERVATION(S). Please tell us what each reservation voucher says.
If not, we can only give you limited advice until you receive the tickets. Although reserved seats are not provided by ATW with Advance tickets, they do issue reservation vouchers for specific trains marked "
Coach * Seat ***". They call this a
reserved place system. With an Advance ticket, you must travel on trains for which you have a
reserved place. You may have more flexibility with any train(s) on your itinerary for which no reservation vouchers have been issued, but we are not yet able to give you detailed advice.
EDIT It is now clear from your latest post that you will indeed have reservation vouchers for the four ATW trains. You
must travel on these trains. You have a little more flexibility with the two Northern trains.
I've just managed to confuse myself intensely! Surely it is either a case of them being valid or otherwise and is not related to the guard's opinion?
Indeed. Using different ATW trains to travel via Newport would not be valid.
