Promoters of Crossrail 2 were this week told to be more up front about the potential impact the mooted £12bn cross-London rail line could have on other rail services.
The London Assembly transport committee this week said it supported the scheme, but urged the project’s promoters to be clearer on how it could harm other services south of the capital.
Transport for London (TfL) and Network Rail launched a joint consultation on the route of the north-south London rail line earlier this month.
There are two options. One is a metro route running run almost exclusively underground from Wimbledon in south London, north to Alexandra Palace. The other, regional, option would follow the same underground route but with overground extensions to Twickenham, Epsom, Tottenham Hale and Cheshunt.
“We are generally in favour of Crossrail 2,” said the transport committee chairman Valerie Shawcross. “It is an absolutely essential scheme for London on the whole, but we question whether the promoters are being up front with us on some of the possible impacts of the regional option on existing rail services.
“We are worried that we are not being told all of the possible downsides to the proposals,” she added, citing Thameslink and the London Overground as similar projects that have had negative knock-on effects on other south London services.
