GA 10 car 720 allocations CMB-LST

[700720]

I was wondering if anyone could give details on generally which CMB-LST/LST-CMB services are formed of 10 coaches (primarily on weekends but weekday information would be useful too). On the GA website’s “less busy trains” section, it lists all the services and if they are 5 or 10 cars but this only works Mon-Fri towards Liverpool Street for some reason.
I remember that on Saturdays all CMB-LST services were 10-coach 720s but this doesn’t seem to be the case today. All the 10-cars I can see today returning from LST is the 17:28 stopping and 20:58 semi-fast.

CMB - Cambridge North
LST - Liverpool Street

Any information would be appreciated!

On Monday-Friday the only 10 car evening peak departures from Liverpool Street are the 1737 fast and the 1713/1743/1813 slows.

10 car trains can run on some Saturdays, for example when other routes are shut, but it isn't the norm, other than on one of the cycles as you observe today. There is a 3.5 hour cycle so the 1728 and 2058 are the same working.

Of note that (almost) all trains today (Sunday 29 September) between Liverpool Street and Cambridge North are formed of 10 coaches, because of engineering work on the Shenfield line.
