Yes. I read the various east-west studies a few years ago, and the
common theme was congestion relief in the Essix [1] - City - Oxford
Circus corridor. The current plan won't do much for congestion east of
Liverpool Street, because it adds neither track nor trains (alright, it
adds track between Liverpool Street and Stratford - but is there any
plan to use the capacity released on the surface line?), but it should
help enormously between Stratford and Oxford Street.

There will still be residual services on the slow lines to/from
Liverpool St in the peaks, Crossrail doesn't replacement all of the
existing service, so the total number of trains into Liverpool St (ie
high and low level conbined) should be somewhat greater than now. The
Network Rail 2nd gen RUS for London and the SE covers the subject, and
suggests that 8 current services are removed in the high peak hour to
make room for the 12 Crossrail.

Is that something that couldn't be done without Crossrail? IIRC at
Liverpool Street the constraint is the station throat; putting the
Crossrail trains in the pipe should ease things there, so i suspect the
answer is yes.

Also, 12 Crossrail in the peak hour? I thought 16tph were going to
Shenfield?

There are also some loosely worded plans to make more use of the West
Anglia routes into Liverpool St. Ideally the trains from the Lea Valley
into Stratford would be increased and run through to the terminus, but
they are on the wrong side of the mainlines.

Exactly. It's going to be oddly quiet between Pudding Mill Lane and
Liverpool Street for a while.
