Transport for London has backed the plan to build a second Crossrail link across London. The organisation says a new link is needed because of population growth and the extra passengers using Euston after the High Speed Two rail link is finished to Euston.
But TfL's Managing Director for Planning, Michele Dix, says construction on Crossrail 2 will only start after the first Crossrail link is finished in 2018.
