No, the Jubilee Line does not use Full ATO, all Trains are driven by
Drivers. The JL does thogh use ATP, which will be affected by a signal
Failer.
Should a signal Fail to a restrictive Aspect (Red/Off) the trainstops will
rise, and prohibit the movements of trains past them.
The Safe working of the signaling system is designed to bring things to a
safe situation in the event of a failere of any kind, most of which can be
fixed fairly quickly.

As signal failer omn its own in unlikely to be the cause of a services
suspension, but i certainetly havent seen any reports of anythig majr with
the signalling/safety systems
It is more likely that there are other factore included (LUL dont close
lines likely.. its bloody awfull trying to get trackside to do anything!!)
It all depends on what definition of "Signal failer" you use:
-- Was it a Sole Signal failer, or multiple
-- Was it a Track Circuit Failer which resulted in a signal showing a Red
-- Was it a signaliing system Comms Error
-- Was it an Error on the Signal Control Center
or any other of a wide range.

Any chance of that again but in English?
