Compulsory reservations would solve the problem of extreme overcrowding and people left on platforms, and enable yield pricing to spread the demand bulge out.
I will now retreat into my bunker and await the incoming
I mean, that is a choice you could make, but realistically, who would consider that acceptable for a regional service? I certainly would not!
from what I hear, TfW has a lot of rather full trains nowadays, and the small number of their services I have used where all very busy.
As others have pointed out, strengthening or running a relief for one service can often be done, as evidenced by things like the rugby specials, etc. upthread.
Strengthening many services, on the other hand, is rather harder, because TfW, or any operator for that matter, doesn't have loads of extra stock standing around. Some more stock is joining the TfW services in the near future, so that should help with general overcrowding problems.
To some extend, we may just have to accept that for big events rail services will be very busy, though ideally they wouldn't end up leaving people behind.
It's clear that a lot of people in the railway work very hard to deliver a good service, and tbh in general most of my problems are with the government, rather than the operators
