What? TfL has no ambitions? The crossrail is the biggest construction project in the whole Europe, and it is still not finished and they are already planning for the crossrail 2 that will be started in the next 3-4 years. These are huge projects, much more important than Musk proposal that in London would have been simply ridiculous given that the crossrail alone will move 200 million people per year. If they went for the proposal discussed here instead London congestion would have exploded given the abismally low capacity of this boring company project.
