Northern Line goes south
 

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

Yes, that's something I often wonder with LU disruptions. Probably
what they really mean is that they're running a reduced service, with
extended intervals between trains.

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.

No, the trains do run to a timetable. This may mean that train 123 is 20
minutes behind time or, more likely, that trains are taking longer
between stations than they should.

Most of us know that

It used to be possible to get a physical copy (I'm beginning to wish that I
had kept my "collection")

And very possible an online variant, as for busses until they took those
away (or hid them very well) in favour of just informing people using the
journey planner.

This may mean that train 123 is 20
minutes behind time or,

but if everything is running 20 minutes (or 2 hours, or 4 hours, or 6 hours)
behind time, because all trains were stuck in the depot for that length of
time, who will notice other than the dispatcher (whatever his job title is).

It's all very well TfL telling us that trains are running with severe
delays, meaning that individual trains are running behind their nominal
timetable, but if there still a service frequency of one trains every 3-4
minutes, in the real world, who cares?

OTOH if they mean something else, such as extended intervals because fewer
trains are running, or because of extended dwell times at stations caused by
congested platforms, they should use a more appropriate terminology.

The definition for Severe Delays is based on how the trains are perceived
to be running, not on if they are running according to the WTT. For
example on the Jubilee line during peak times gaps in service of more
than 10 minutes are a severe delay.

See

for some examples.

East and westbound on alternative pages - might very possibly make sense in

Hid them so well that I had to type "london underground working
timetables" into Mr Google's Information Emporium to get them to come up
as the first result.

They're for drivers, not for spotters. Normies never see them. Why are
you channelling Boltar?

The other fact not mentioned is that when the service restarts all of
the drivers will be in the wrong places, which means they'll be hitting
their legal working hours limit in odd places unless the controllers
turn various trains in various places for the next few hours. This won't
affect the central area much, but you will probably get unusually long
intervals at Barnet and Edgware sporadically for the rest of the day.
