 In August 2012 the Secretary of State for Transport, Justine Greening, asked HS2 Ltd to consider alternative routes for connecting HS2 and HS1.An alternative scheme for the HS1–HS2 link was put forward by Transport for London (TfL), who proposed incorporating the link into the projected Crossrail 2 route (see below).Prior to the debate on the HS2 Bill in Parliament, Sir David Higgins, chairman of HS2 Ltd, expressed the view that the Camden railway link was "sub-optimal" and recommended that it should be omitted from the parliamentary bill.
