Snow on the line
 

The forecasted snow has arrived in London, and knocked out big chunks of
the Underground. For example, in northwest London, both the Met and Picc
are suspended because of power supply problems. But, oddly enough, the
Jubilee and District are reported to have a good service.

The forecasts I was looking at yesterday were predicting wind in London
but not snow.

I'm in Barnet where the council allegedly began gritting at 4am but
there wasn't much evidence of them until mid afternoon and most of the
buses were suspended for a while.

Naturally as the snow arrived the underground fell apart. I mean snow! In
winter! Fancy that! Power supply problems? Who the **** are they kidding.
Perhaps if they were more honest with their excuses people might not hold them
and the various rail companies in contempt.

I'd lay a lot of money on the ****wits not listening to the weather forecast
and not spraying deicer on the power rails or sending up a train with any
kind of brush on it. Then next morning, "Oooo, theres snow on the rails, train
won't move! Quick, lets blame the power supply and make it sound like its

I don't know what the problem was but it was very annoying and poorly
communicated.

I was doing KX to Southgate at around 10am.

15 minute wait for any train (no problem yet) but first train was to
Arnos Grove so we waited for the next one to Cockfosters.

Got on train - as we set off the automatic announcement '... to Arnos
Grove'

Every single station to Bounds Green had the platform indicators saying
the train was to Cockfosters. At bounds green platform indicator said
Arnos Grove with a Cockfosters train 6 minutes behind.

Got to Arnos Green, train did terminate, to be immediately presented
with an announcement 'no trains going further than Arnos Grove, buses
stopped running 30 minutes ago, cab conpany says there are no drivers.
You cannot continue your journey from here'

Not a single announcement until the only option was to turn around and
go back. Not even an announcement from the driver that the platform
indicators were wrong.

Disappointing.

Thats par for the course.

Even when the buses do run from Arnos Grove its usually a 20 min wait anyway.

Not a single announcement until the only option was to turn around and

You should have walked tbh. Depending on what part of southgate you were going
to its between 15-30 mins from arnos grove at a normal walking pace.

Its wasn't a power supply problem, the power supply was fine. Its a power
collection problem arising not from equipment defect but from a wetware
defect inbetween the ears of LU managers and staff. The correct announcement
should have been "We ignored the weather forecast because we're ****wits and
now our trains are snowed in"

I don't think that was the problem. I think it was genuinely a power supply
problem, as it also affected the Piccadilly line Uxbridge branch. Later,
when the Met line was running again, the Amersham branch continued to be
affected, and that might have been more to do with snow/ice on the running
and conductor rails.

That would contravine the railway bylaws (section 6). I therefore
doubt that any reasonable person could consider it the correct
announcement. Want to try again?

Also the Central line east of Leytonstone. Ice on the conductor
rails was the only thing I thought was likely; but the snow started
after the service and I'd've thought the current would have warmed
the rail enough to melt it - it wasn't _that_ cold, after all. What
do you speculate was the root cause? I'm struggling to come up with much
that seems plausible to me.

Yeah, I'm sure they pay attention to every fine detail of railway law when
it comes to snow clearing.

No. Because its EXACTLY what happened last time in 2013.

A power supply problem which affected different lines on parts of the network
seperated by 20 miles. Hmm, lets think about the likelyhood of that for a
second vs the didn't-bother-to-clear-snow-from-the-rails scenario...

You misunderstand. Your proposed announcment breaches the bylaws;
therefore no reasonable person can consider it the correct annoucment
- even if your understanding of the root cause is correct.

Epping and Amersham were both affected, and are about 30 miles apart
as the crow flies, and 44 miles apart by track kilometerage.

So what? There were a number of "power supply problems" over the network.
Now either you're naive enough to believe all these substations failed due to
some snow, or alterntively its a load of BS to cover up not enough de-icing
trains being sent around the network. Take your pick.

Some may be, I think others are in shafts. But not all open lines were
affected, either. For example, the District line was fine. The closure of
the whole Met and Uxbridge branch of the Picc probably was a power supply
problem; the later problem on just the Amersham branch was more likely to
have been icing on the rails.

Sure, a major power supply problem that hasn't happened since god knows when
and purely coincidentaly happens on the first major snowfall in london in 4
years. Riiiight.

Well all the other substations around london seemed to cope. Just LUs. Guess

What's a plausible alternative?

Problems with substations?

What's the mechanisim that caused it? I'm by no means an expert, but
I can't think of obvious problems with substations that would cause
widespread issues when they're snowed on. Localised issues, yes;
but nothing systemic.


Obviously this is all just speculation, but there might have been multiple
different problems which all got summarised under one heading. Fo example,
could the signalling been affected by a weather-related power cut? Or, if
Neasden depot was hit, that could have affected the Met trains leaving the
depo (though I think the Jubilee was unaffected).

Snow on the line

Occams razor - they didn't clear the snow and ice off the conductor rails
but decided to mince their words.
