I'm not sure about this. I wonder whether upgrading the present network would be the better option. I live in north Manchester, the trains into Manchester are over full and grubby much of the time. Rail links could be improved, or could they> The roads are so overcrowded, the motorways especially are increasingly traffic jams at busy times. Driving north or south on the M6 is usually a stop/start experience.
Train and other forms of public transport seem very expensive.
My husband and his group of friends are all pro HS2 and they use the railways much more than I do. I read recently that one of the advantages would be to extend the commuter belt for folks who work in London, but can no longer afford to live there. I was irritated by that, as I feel the north west, north east are already suffering from the way in which business is so london centred. I'm sure the same applies to Wales, though I know nothing about rail links between Wales and London.
Will HS2 improve work opportunities in the north west, north east, wales, and other parts of the country that are really struggling?
