Signal failure on the central line?

(The Central Line still has a relatively conventional signalling
system, it's just conveyed to the train through the track rather than
to the driver through coloured lights)
What about the starter signals at stations? They are a bit differrent from
conventional LU signals, however, in that they show three aspects.
Green: All trains proceed
Lunar white: All ATO coded trains proceed.
Red: All trains stop.
Same situation on Victoria line trains, although it appears that this system
is being replaced.
