Only in the light of looking at the housing issue can you clearly see why the route chosen was selected.As we have covered before, south of Elephant & Castle the first major issue has always been to decide a route to Lewisham.If one fails to appreciate that then one fails to understand a lot of the decisions the project and its backers make.People can (and rightly will) get bogged down in arguments on whether it should go from Wimbledon to Clapham Junction via Tooting, via Balham, via somewhere else or directly without an intermediate station, but these are mere details and hardly matter at the macro level.For almost a hundred years people have talked about extending the Bakerloo line.The latest consultation report on doing this has now been published.This would initially seems to be an oversight as Crossrail 2 is proposed in the same time frame.
Many different options and their combinations were considered.
As a result, the Old Kent Road route has been selected.
Something else that has been considered is whether to just go to the Old Kent Road and terminate there or, alternatively, to go a little further and terminate at New Cross Gate.
A failure to grasp this will result in a failure to fully understand why the decisions made so far have been made.
For our purposes it is easier to give the main conclusion of the report and then look at how it arrived at it, rather than the reverse.
