The transport body in the Capital has launched a third public consultation on the project after making changes to the proposed route running from south-west to north-east London.

Previous consultations on Crossrail 2 have shown overwhelming support for the railway from the public, businesses and others.

Michele Dix, TfL’s Managing Director of Crossrail 2, said: “Crossrail 2 will provide a UK-wide economic boost supporting hundreds of thousands of new homes and jobs.

“This consultation gives people the chance to comment on where we are proposing to put station entrances, work sites and ventilation shafts needed to run Crossrail 2.

“As development of this vital railway continues, we will be taking on board feedback from the consultation to progress the designs for the project, so that we can open the railway by 2030.”

Latest proposals include a new route from Clapham Junction to Wimbledon which would stop at Balham rather than Tooting Broadway due to challenging conditions for construction at Tooting.

In the north, New Southgate would now be linked with Seven Sisters with a stop at Wood Green rather than Alexandra Palace and Turnpike Lane.

If Crossrail 2 gets government funding and approval to progress, construction could begin in 2020.

Crossrail 2 would serve central London through a 32km twin tunnels between Wimbledon and Tottenham Hale and New Southgate, connecting with existing National Rail networks in Surrey and Hertfordshire.

An estimated 200,000 new homes and 200,000 new jobs could be supported by the scheme, through the housing and economic growth it would support, with 60,000 full-time jobs also being supported through the construction and operation of Crossrail 2 and across the UK in engineering, construction and manufacturing through its supply chain, driving hundreds of millions of pounds to regional local economies.

It has been estimated by KPMG that Crossrail 2 could make a significant contribution, worth up to £102bn, to the UK’s economy by boosting productivity.
