This Sunday, for the C-stock railtour:

Train 07:32 Cambridge [CBG] London Liverpool St [LST] 08:43
Walk 08:58 London L'pool St [LST] London Fenchurch St [FST] 09:02
Train 09:10 London Fenchurch St [FST] Limehouse [LHS] 09:14
Tube&DLR 09:19 Limehouse [LHS] Moorgate [MOG] 09:35

Alternatively:

Train 07:28 Cambridge [CBG] * Finsbury Park [FPK] 08:22
Tube 08:27 Finsbury Park [FPK] Highbury & Islington [HHY] 08:45
Train 08:51 Highbury & Islington [HHY] Shadwell [SDE] 09:06
Tube&DLR 09:11 Shadwell [SDE] Moorgate [MOG] 09:25

Does this indicate that the normal service on the Circle/H&C is
suspended, otherwise why wouldn't they just show connecting trains from
LST/KGX to MOG?

* Train to Kings Cross.
