The promise is better roads, tubes and cycling routes. The price is ten years of fare increases.
Transport for London confirmed today it wants to raise fares, above inflation, for a decade, and for the first time, in writing, set out plans for trains that don't need drivers.
Transport Commissioner Peter Hendy insists that doesn't mean the trains will be un-manned, but the move is likely to spark protests from unions opposed to driver-less trains.
The decision to double spending on London's road network is also proving controversial. Isabel Dedring, the Deputy Mayor for Transport, says that they have to invest in the roads to encourage more people to use buses and bicycles.
But Labour's Val Shawcross, who sits on the London Assembly says that "public transport passengers are being robbed in order to pay for roadworks for the next decade".
