I think these might be directed at me.
two things:
1) it doesn’t ignore the people who would make the journey if the connection was better. Even if every single person who flies from Birmingham, East Mids, Manchester, Liverpool, Glasgow and Edinburgh to Paris or Brussels decided to use the train instead, it would amount to about 3 extra people a minute each way between Euston and St Pancras in service hours. This is based on Pre covid passenger numbers. And I’m sorry, but changing what will be a well signed, reasonably pleasant 10 minute amble between the two stations into a moving walkway or people mover isn’t going to convince very many of the fliers to suddenly take the train, even if HS2 worked at light speed and was free.
2) as I have explained - evidently not very well - this specific issue has been looked at. Many solutions (some of which are upthread) are simply not practical - mostly on a social economic basis, but sometimes because of the laws of physics. This is not about not being ‘open minded’, it is simply explaining how these things work in the real world with real survey data and an understanding of what challenges need to be overcome.
I’ll ask again, what practical solutions are there?
