The train is control by the ATO cable signals , not a cluster of coloured

a computer failure?

Yes. For reasons I can't remember, there are only something like 5 or
6 possible phrases they'll use to explain delays to the public.
"Signal failure" is very broad and could mean any kind of signalling/
ATO/points/etc problem. "Passenger action" is another one.

"Signal failure" is at least meaningful (though posibly slightly
misleading). The phrase "passenger action" deserves to be sent to the
same hell to which I would banish all management speak. ("There's no I
in team" -- "Unless you're French", I always reply.)
