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.
