The whole Northern Line has been suspended since just before 6am this
morning, because of 'signal systems failure at the main control centre'.

"The service had reopened by 13:00, but is now running with severe delays"

yep all trains are running 7 hours late

how will anyone notice?


If they tried to get in on the Met with its signalling also not playing
ball they wouldn't have. Seems that these modern systems have quite a few
single points of failure instead of being distributed with failover backups.
