Dispatchers falling asleep

Interesting. That’s something you can’t do on German mechanical signal boxes! Signals can’t be moved without a locked route, and after a route is locked and the associated signal has been cleared and reset to danger, it cannot be cleared again; the route has to be released and re-locked first.

Italian colleague here!

Here, on relay devices (ACEI) you have a key that can force the signal to danger or let it set to clear, but doesn't affect anything else; on electromechanical devices (ACE), the signal lever can be put a little bit backwards to set the signal to red, although you need to remove the route locking before you can put the lever completely back into its resting position. On both, in theory you could play with the signal as much as you want.

On Polish type E devices I see there's no way to do that; I wonder if it can be done with mechanical devices.
