In which case, half the time ‘saved’ on a hs2 train is probably lost by having to travel to an out of city location to get on it in the first place. How typically British.
In the case of London to Nottingham, it'll probably be worse. There is at present no direct train line between where the East Midlands Hub will be and Nottingham station but you can get a tram to somewhere near there. It takes just over half an hour. I dunno how fast these high speed trains are going to go but considering they need to go via Birmingham when the current London-Nottingham line does not there's not a chance in hell it'll actually save any time at all. Most likely it will be slower. Slower and more expensive.
