Jubilee line disruption 26/04/18

[700007]

Today for most of the day, the Jubilee line has been subject to a full suspension as a result of a 'power failure' affecting the signal control room. I believe I know the answer but would there be any back up signalling centres in the event of this happening, albeit the service running at a reduced rate?

Was it a power surge of some sort affecting this?

I was also wondering whether hackers could have caused this sort of incident even if it is not on this particular occasion?

Reoccupied main control centre. Trains finished at Sunday times yesterday.

There's some amazing nonsense being spouted on various groups and forums about this failure. Some self-proclaimed old timers putting forward all sorts of theories about substations and traction current, even though this has nothing to do with that. Then an even more bizarre theory that it's all somehow the fault of graduates! One thing I've learned over the years is that when grey-haired 50 somethings turn up at an incident and claim to know what they're doing whilst making a point about how many years they have behind them, it's often a good idea to get them out the way as quickly as possible.

From what I gather the VCCs weren't affected, but a considerable amount of other equipment in the control centre was. In theory it's possible to take control of the TBTC from a backup location (as was done), but this isn't straightforward nor quick to implement, plus there would be the issue that many operational procedures require confirmation of implementation from the control room technical officer (known as the VCC operator), who in turn needs to have a working terminal.
