24 tph is probably the max achievable. They're not planning double
tracks or double platforms at station. On current plan, the bottleneck
will probably be at Liverpool Street on West bound trains, since the
majority of the passengers will want to get off, replaced by the a
similar number of passengers wanting to get on.

But a large number of passengers on the Shenfield line already want to go
west of Liverpool Street. There's crossplatform interchange to the Central
Line at Stratford, where something like 2/3rds of the train empties out.
This huge number of passengers that you assume only want to go as far as
Liverpool Street doesn't seem to exist in my experience.

No, they may not want to go beyond Farringdon. How many of the 2/3
changing at Stratford only go to Bank? My guess would be about 1/4
will want to take CrossRail (longer term, this will increase, as
people will be prepared to accept jobs in Bond Street or Bond Street
workers might move to Shenfield).

But what's true for Shenfield will be true for the Stansted and Grays
and other lines. Except the 1/4 here (making 3/4 of a CrossRail train)
will all be trying to board the CrossRail train at Liverpool St, just
as the 3/4 will be trying to get off.

I think they should put in double platforms at Liverpool Street.

The situation will be somewhat complicated by Kent commuters getting
off the CTRL trains at Stratford to board CrossRail services.
