Completely agree ambient.

The routes do provide the interesting prospect of interchange at Brockley and at New Cross Gate, so that we will have one change to all of South East London.

Sometimes the easier developments, like Bakerloo have a habit of being realised slightly faster than other projects, like an airport on the Isle of Grain. I could imagine that one branch could be partially built and then extended. However, a lot of the costs would be in the first section beyond E&C.

The orbital routes are also interesting but likely to be seriously expensive. But the plan does also include the take over of most metro services by TfL in the next 10 years - essentially turning our line, South Bermondsey line, and a few others into Overground managed routes.
