ELL Phase 2 in respect of Thameslink Phasing

all good stuff snipped

I must sit and read all that lot.

It does occur to me that maybe a possible but expensive supplementry
solution to inner south London surface rail capacity is to revive
extending the Bakerloo line through the area. Of course thats
something thats been sat on for a goodly long time looking as if it
has no hope of ever getting going. I've not seen much about geological
issues or routes but am I right in thinking various schemes have been
worked out ?
