At turnarounds involving non-passenger sidings (e.g. Amersham), a staff member walks the length of S Stock trains and locks out each set of doors as they pass by.
This appears to be done with the internal door open button on the adjacent non-released door (the one not against the platform).
I'm not sure however, whether this is just a long press, or a coded pattern of pushes, or some sort of wireless token with a reader embedded in the button facia. Also, does the train need to be put in 'lockout mode' before this functionality is enabled?
