Hello, newbie here, but this looks like the sort of place where I might get an expert's opinion, so here goes... For many years now, I've been travelling between Southampton Central and Crewe, via London using advance tickets. In the past, these tickets would say "Virgin WC and connections" in the route area and I'd have a mandatory reservation on the Euston-Crewe service. There was never much said about the Southampton-Waterloo section though. I was told by a ticket retailer that it was a connecting service and considered "freesale", which meant that the ticket terms were more flexible. Often, I'd break a return journey and spend a few hours in London and catch a later SWT service back, all without any problems. Recently, on a return trip back to Southampton, I made the EUS-WAT connection in good time, so was able to board the half-hour earlier WAT-SOU service. On-board, the guard asked to see my reservations and pointed out that I had a mandatory reservation on the later train. Sure enough, looking at the reservations, I did indeed have a mandatory reservation for the connecting service. He was kind enough to not make a fuss about it, but said I should be aware of it for the next time. So, my question is has this always been the case, or has it changed recently? I've not been able to track any information down about it. Any input on the matter would be gratefully received. I'm making another trip in a few days and I'd like to know where I stand. Thanks in advance!
