If it's the same as East Coast, then even if you are going one stop and there is space, you may be refused unless you have a reservation - but reservations are available right up to departure, so it's not really a major problem (unless you are boarding from a station where the ticket office is closed, then I'd hope the guard would be understanding)
Unfortunately, last time I checked, XC and TPE close reservations the night before (but TPE don't mind if you don't have a reservation - space permitting).
Well, I've (personally) seen one of your colleagues try and stop bikes with reservations boarding at Euston and according to ticket office staff at Euston it isn't an uncommon problem.
Given that, I'd say a warning about potential problems is quite appropriate.
Unfortunately I hear many problems about staff behaviour at the gateline at Euston. I am sure the members of this forum are not in any way engaging in the business of refusing valid tickets/reservations, but unfortunately
some gateline staff are. And several complaints later, the problems persist. Clearly, there are some issues with
some staff there. It is a shame that a small minority of badly behaved RPIs are giving the team a bad name.
Examples include:
* Not allowing a Travelcard +extension because the Travelcard was on Oyster (which is irrelevant) and telling the customer to buy a new ticket.
* Not allowing a more expensive route Banbury ticket (the excess was £0.00) and telling the customer to buy a new ticket.
* Telling a customer with an Alexandra Palace - Alexandra Parade ticket that their ticket "must be a season ticket" and denying him entry, then eventually accepting it wasn't but then denying via Manchester is a valid route, eventually they admitted their mistake.
* Refusing to accept valid tickets and refusing to look up the restriction code up themselves, simply declaring all Off Peak tickets invalid because
some Off Peak tickets are invalid at that time.
It's unacceptable and anyone using Euston needs to be careful to know your rights, if your ticket/reservation is valid make sure you assert that it is valid and do not let them bully you. Also, if barrier staff do obstruct you, get their name and make a complaint, as it's important that the ones responsible are dealt with and not allowed to give the good staff there a bad name.
