But after a meeting this week with HS2 chairman David Higgins to discuss the plans, Mr Khan said Crossrail would not be too overcrowded if trains terminated there permanently.
Mr Khan told LBC radio yesterday: “The good news is that HS2 get it and HS2 want to work with the council, with local residents, to make sure they do right by Euston, the residents around there as well.”
However, Lord Turnbull said the best solution was still for trains to stop at the Old Oak interchange in West London, until plans for the last four miles of track were redrawn so HS2 could tackle the issues.
He added: “This would give time for the design problems at Euston to be sorted out and would make the construction work at Euston, once a better plan has been agreed, easier to undertake.”
In the longer term, he said that some of the trains could stop at the interchange — meaning Crossrail would have capacity to cope — while others could run on to Euston as originally planned.
