Some more minor changes from Monday;
The 06:56 Southminster to Wickford becomes a through train to Liverpool St.
There is an additional 06:32 Clacton to Liverpool Street formed of 12 x 321.
The 07:20 Harwich Int is strengthened to be 12 x 321.
So that gives an additional 16 cars of capacity on the GEML in the morning peak plus whatever the Southminster is (5 x 720?), that should help.
No additional trains in the evening peak though but with the extra morning units perhaps the 17:36, 17:43, 18:02 and 18:16 could be strengthened as they are all 5 x 720 or 8 x 321.
