Liverpool Street - Upminster is for two reasons:
(1) duplicates Central Line to Stratford, hence Stratford is legal;
(2) late at night when Fenchurch Street is shut, hence Maryland and
Forest Gate aren't.

Fenchurch Street no longer closes early (22:00). Two trains (22:58 and
23:58) are timetabled from Liverpool Street to keep the drivers route
knowledge up. C2C also use Liverpool St some weekends during engineering
work west of Barking - this weekend being one.
