No. The core demand for passenger journeys is far greater between
Metroland and the City than between Notting Hill and the City. The
same applies for Essex-City journeys versus Liverpool St-Tower Hill
journeys.

What? *This will, of course, explain why the Central Line is empty in
the peaks between NHG and Bank / Liverpool Street. Clearly there is no
need for Crossrail then!

The sub surface lines - all of them - are heavily oversubscribed in the
peaks. *If they weren't, as you allege, then what is the justification
for the Sub Surface upgrade and the additional implementation of 7 car S
Stock on the H&C / Circle routes?

Eh? Yes, of course the SSL is massively overcrowded in the peaks, and
I've never claimed otherwise.

But the vast majority of SSL peak passengers are trying to get to the
City, either from west-of-Earl's-Court or east-of-Whitechapel on the
District, from northwest-of-Baker-Street on the Met, or from west-of-
Paddington on the H&C(&C). The Circle is an irrelevance to them: Met/
H&C passengers can easily walk to all City destinations from the Met
route, and District passengers to all City destinations from the
District route.

Outside of the peaks, when flows are more evenly split throughout
central London, the Circle becomes relevant.
