The DfT has clarified the rail responsibilities of the various minsters under Grant Shapps as Secretary of State.
Chris Heaton-Harris has responsibility for Rail (and therefore franchising).
Paul Maynard has responsibility for HS2, NPR and TP Upgrade, Crossrail, East West Rail, and Aviation (inc Heathrow expansion) - so major projects.
Baroness Vere has freight (inc rail), and light rail.
Looks like Paul Maynard has either the best or worst job in transport, depending on your point of view and how things turn out.
Last time round he was the franchising minister.
