The Olympics bid is widely considered a long-shot.
Not least by the IOC. Realistically, it's a two horse race between Paris and Madrid, although the only decision which would surprise me would be one in favour of Moscow. The IOC seem to think similarly, their overall ratings of the five cities being as follows:
1 Paris 8.5
2 Madrid 8.3
3 London 7.6
4 New York 7.5
5 Moscow 6.5
This breaks down thus:

In terms of transport, the Madrid bid is pretty amazing. There's a metro extension, two new suburban rail stations, new high speed rail lines, and an expansion of Madrid Airport.
I can't find any plans for infrastructure improvements in Paris, but they don't really need much, as their Métro and RER are excellent to begin with. The Moscow site also seems vague.
London of course has come up with some really dumb ideas, like extending the East London Line to run from nowhere much to nowhere much. There's also a totally imbecilic idea of running high-speed shuttles from London St Pancras to Stratford International whilst maintaining a whole Eurostar and High-Speed Kent service. The IOC were totally scathing about London's infrastructure: the railway network is "often obsolete" and the IOC want huge capacity and safety upgrades; they've also smelt a rat at the dispersed nature of the sites, some over 30 miles from the Olympic Village, and have deemed the supposed average speed of buses between them at 35mph "unrealistic"; furthermore they've noticed that the main arterial roads are at capacity already.
I don't think anyone needs any filling in on NY's transport plan.
