The busiest station in 1927 was Charing Cross with over 33 million

I presume this is the one now called Embankment. Any reason why this one
should have been so busy?

Next
busiest (in declining order) were Oxford Circus, Piccadilly Circus,
Hammersmith,

Any indication which Hammersmith station this was?

Bank,

I don't think the escalator to Monument had been put in at this stage had
it?

Most people worked 6 days a week in 1928 - 5 full days, Monday to
Friday, and half a day on Saturdays. Timetables and rolling stock were
geared to these. "In London there is a generally heavy workmen's traffic
from the opening of the lines, at about 5 o'clock, till the closing of
the period of availability of the cheap workmen's tickets at 7.30 a.m.

An early hours off peak service? Would such a concept work to spread the
crowds if tried today?

Was there a service on Christmas Day? But of course. "Chirstmas Day is
provided with a Sunday morning service, though much slacker between 3.0
p.m. and 9.0 p.m., after which the traffic increases again as people go
home from their parties."

Nice. How is one supposed to get to services at St Paul's Cathedral these
days?

"On Good Friday a Sunday service is worked throughout the day, but
trains are started an hour earlier to make provision for the appreciably
heavier workmen's traffic caused by the redecoration of stores, hotels
and apartment houses, which generally commences in London on Good
Fridays."

Interesting. This year the tube seemed to be running a Saturday service on
Good Friday (although the trains were far less consistent, with a hideous
mix of Saturday and Sunday services designed to maximise missing
interchanges).
