What do you want to ask Philip Hammond, the transport secretary?

Everyone's got a gripe about transport. Philip Hammond, the transport secretary, is the man in charge of dealing with them. I've got an interview with him on Thursday and I'd like to know what you want me to ask. At the moment the biggest project on his plate is high-speed rail, which, depending on your view, is either a far-sighted investment that will transform Britain's economy or a wasteful, multibillion vanity project. There's a speech from Hammond setting out the case for high-speed rail here, the consultation document is here (pdf), and the Department for Transport's high-speed rail site is here. For a summary of the case against, this polemic from Andrew Gilligan in the Daily Telegraph is a good starting point. But I don't want to focus exclusively on HS2 (high speed two – HS1 is the line from London to the Channel Tunnel). On Monday this week Hammond announced a series of measures relating to drink-driving, including his decision not to lower the drink-drive limit. Other recent announcements have been on subjects like repairing winter potholes, changing the rail franchise system, modernising rail carriages and promoting electric cars . I'd be interested to hear suggested questions on these topics, or anything else in the transport portfolio. I might also try some questions about the general political situation. Hammond was shadow chief secretary to the Treasury before the election and we'll be speaking on the day after the budget. His thoughts on the coalition may be worth hearing too. A fairly conventional Conservative (here's his Wikipedia entry), Hammond is now teamed up with the leftish, free-thinking Liberal Democrat Norman Baker, who is based in the department as a junior minister. I'm curious about how they're getting on.
