Crossrail 2
 

Last Saturday Peter Hendy was one of the guests on Ken Livingstone's LBC programme.
HS2 was discussed and Hendy said he believed it would go ahead but that
Crossrail 2 would be essential to cope with the number of passengers at Euston.

Now, first I'm not sure that HS2 will massively increase the number of
passengers alighting at Euston. How many trains an hour are going to arrive at
Euston? Does anyone have any ideas about this?

Second, this was the first I had heard about Crossrail 2. It seems this is the old
Hackney/Chelsea line idea but changed from being a tube line to a full size
railway. Will that not greatly increase the costs? How far advanced is this idea
and are there any plans to extend the line beyond either Hackney or Chelsea?
