I once spent a very enlightening hour chatting to a consultant whose job was to lobby government and advise on environmentally friendly transportation. He was/is heavily involved with Crossrail amongst other things.
Regarding bikes on trains – from what I gather the (unofficial) stance of HMG is a 'Dutch' model where the emphasis is put on providing bike parks/secure storage at stations rather than making allowances for the physical transportation of bikes on the carriages themselves. If we commute by bicycle we should all move to having two bikes apparently – one at the home end, and another at the (for me, London) work end. I think the current situation whereby folding bikes are allowed on trains is wholly at the discretion of the rail companies and could be changed/removed without any discussion or consultation – the policy is that we should be grateful for that alone rather than pushing for the reinstatement of any form of guards van / area on the train specifically designed to hold more than a token number of bikes (not that they're allowed on SouthEastern trains at all between 7 and 10am, 4 and 7pm)….
A complete joke in my opinion. You'd have thought they'd be trying to encourage more people to stop driving to work / to and from the office etc but no, it's about putting the expense (two bikes?) and emphasis on the commuter rather than offering any meaningful way to help facilitate the use of bikes and trains for commuting.
Arrrggghhhh. And breathe…
(for what it's worth I think one of the best things they could do would be to introduce a similar scheme to/alongside cycle2work for public transport whereby you could pay for the cost of season tickets on bus/tube/train from your gross, rather than net salary. It'd help get more people on public transport but the cynical might argue that increasing numbers in anything other than token amounts might require some investment in infrastructure, heaven forbid)
