A relative travelling Hereford to Aberdeen today on a £62 ticket had platform change at Birmingham - and revised platform had 2 trains to Edinburgh ! He took the wrong one( much slower and would miss connection To Aberdeen in Edinburgh )- and was advised to change at Crewe to faster one to Glasgow . However he had to pay £100 before he could board the Glasgow bound train at Crewe. Is this reasonable and can he do anything about it?
another question that may be pertinent.
When asking at Crewe, did your relative ask a train manager / guard if they could broad and continue journey, or did they get off their train and ask station staff / ticket office if the ticket they held was valid, having realized they had got on the wrong train at Brum? (or being told that by the train staff whilst en route Brum to Crewe).
If the former a member of train staff may have showed discretion and allowed them to continue their journey on that ticket. But if eg ticket office staff were asked, they may correctly advise 'that ticket is not valid here, and you have missed the train that it was valid on, the only way you can continue your journey is to buy a new ticket which we can sell you for £x'
As an aside, this is one of the reason why unless a decent financial saving is on offer by buying an inflexible 'Advance' ticket, I avoid them. Only each individual passenger can decide what that saving trade off is worth to them.
Despite the comments on here, I can fully see why an irregular or slightly distracted traveler might get on the wrong train at a station they are not fully familiar with, or when departures are at similar times (I did it myself come to think of it in France, on a TGV, when 2 TGVs left on adjacent platforms for Paris, at approx the same time - I only realised when someone else came to turf me out of what I thought was my reserved seat that I was on the wrong train...fearful I would get asked to buy a new ticket as I would tend to expect in the UK I went to seek help and advice from the SNCF train manager - his response: an initial bemused look that I had even bothered to ask him about it, followed by a shrug, and then some help finding an unreserved alternative seat. He certainly did not seek any extra money! Perhaps the benefit of a unified national railway system...).
