What I mean is that if a service is cancelled currently, people can cram onto the next train and at least get home. With compulsary reservations, you'd a) have a lot of people stuck in Birmingham who couldn't get home, and b) if your train was cancelled and you're on an advance ticket, how would you book another reservation, even more so if it is cancelled part-way through it's journey.I don't understand your point? If XC cancelled a service today to from Birmingham to Newcastle, the situation would be exactly the same with or without a reservation-only system in place.
I think it would be rather crazy to commute Birmingham to Newcastle on a daily basis, and if it was a journey I was making on a regular basis, I would be booking tickets with seat reservations considering the journey length. I can't think of many examples where that journey would be a regular walk up customer.
I do take your point here, and in an ideal world this would be the case. However, I don't see XC services gaining the required boost in capacity in the next 5 years to make this workable, so at least in the short to medium term this proposal would cause huge problems on the network, with people forced to drive if they want any sort of flexibility at all.To take your point about my apparent proposal for a 100% capacity cut... not sure what you are getting at there other than a reservation only train wouldn't be conveying standing-only passengers.
Capacity here is key. It was one of the most idiotic ideas in the history of privatised railways to think that ordering 4 and 5 car trains to replace HST's was the way forward. I don't want to get into a debate about frequency and the original idea of more shorter trains because that doesn't help capacity at all.
I guess the point I'm trying to make is that with technology as it is, should one wish to travel on an XC service from Birmingham to Newcastle at 17:30 today, that person whether they already have a ticket or not, would be required to reserve a seat on that service - be it via a website, app, ticket office, ticket machine, whatever. If there isn't a seat available, then its a wait for the next train assuming that has a seat.
If a National Express coach is full, you can't book it. If a flight is full, you can't book it. I see no reason why intercity services in the UK should be any different.
