Going to a booking office/ TVM can do that function as well.
Many TVMs can't do it (can't remember if Merseyrail can), and Bache doesn't have a ticket office.
Vast majority of services are non reservable.
Virgin Trains Chester-London (and Liverpool-London) is reservable. Most services for long-distance travel, which (besides commuter trains) are by far the most well-used, are reservable. The services my mum wants to travel on are reservable.
Most folk are traveling for a reason at the times they do, I.e have to be there by a certain time for appointment, start time of game/concert, check in time of flight etc. in reality the totally flexible traveler is few and far between.
Totally flexible? Sure, few people are totally flexible. But many have a window of, say, a few hours, especially for leisure travel. Even if you have a specific thing you're doing, many people would be able to spend more or less time before (or after, in the case of a matinee) the thing they're doing depending on the price of train tickets. If my mum goes to London to see a play she'll probably do other things in the morning, and arrive at a time when it's cheapest.
The industry as a whole has missed this trick driven by franchise agreement targets set by Govt rather than thinking customer.
And yet, online-only reward schemes do still exist.
Never in 25 years have I seen a claim before you travel T S policy.
I'll give you that one; neither have I.
Give me a BR all lines timetable any day.
You're not a normal passenger. None of us on here are normal passengers. I also like having a paper timetable from time to time - but even my grandparents react with incredulity about why I don't just search online.
