Transport for London on behalf of the Department for Transport consulted on the draft safeguarding alignment for Crossrail 2 between November 2014 and January 2015. The Department for Transport confirmed the safeguarded route in March 2015. Crossrail 2 is a proposal for a new rail line between north east and south west London. Safeguarding is a statutory process that sets the boundaries of the land within which the new infrastructure could be built. The aim of the safeguarding is to protect the route from development which could prevent this infrastructure from being delivered.
If the council receives a planning application for development within the safeguarded area then we need to consult TfL to check whether it would conflict with Crossrail 2. For Haringey the route could serve Seven Sisters, Turnpike Lane and Alexandra Palace stations, and on a separate branch Tottenham Hale and Lee Valley.
