Ah, yes, I just read about it, as you say HS2 doesn't connect directly into the city centre, that would require HS3, or the '20 miles more' link (http://www.20milesmore.com http://www.20milesmore.com) The ultimate time saving would be to reduce Liverpool to London travel from about 2h 10m to about 1h 10m, with the standard HS2 'classic compatible' network (https://en.wikipedia.org/wiki/High_Speed_2#/media/File:HS2_classic_network.png https://en.wikipedia.org/wiki/High_Speed_2#/media/File:HS2_c...) doing about half of that, and the HS3/20MM link the rest. The extra link also would provide much greater capacity improvements, whereas HS2 on its own wouldn't do too much on that account. Still, the HS2 improvement is worth having, and it seems inevitable that once that is built, the extra link will follow. Personally I think they should be building HS3 right now, in parallel.
