what its doing there?

Brake testing?

That would be my guess... there are sprinklers fitted on the
northernmost track from Northfields to Acton Town for brake testing.


Yup, it's the dedicated test track where all LU stock goes to test any
changes to brakes, brake pad materials, etc. It's fairly easily accessed

by
all the stock types, as well.

Can the 2009 stock fit through the Piccadilly Line bends at South Ken?


I think so, running very slowly, and ECS of course. It's too large to run
in service through the Piccadilly line tunnels, but was designed to fit for
stock transfers.

You sure? I thought it was delivered by road to northumberland park because
it didn't fit. Seems a lot of effort if they could simply have dragged it

from
Derby.



It was certainly delivered by road, probably to avoid the disruption of the
fleet crawling along the Central and Piccadilly lines. If they'd really
wanted to deliver by rail it would have been much easier to restore the
connection to the NR line thst runs alongside the Northumberland Park
depot.


True. There does seem to be conflicting information wrt the 2009 stock
depending on what source you read. Wikipedia says its wider than other tube
stock - it isn't, but what it does have is a clearly more vertical profile
on the sides before the body starts to curve over. I suspect bashing the tunnel
at the top of the doors on curves is probably the real issue.



It's the same height as other tube stock, but 40mm wider than the 67 stock
it replaced, which was the previous widest stock. You may be right that the
tops of the doors could be the point of potential interference in tightly
curved tunnels.

If that's a real risk, one extreme measure could be to remove the doors of
a test train for an ECS move to Northfields. Another method might be to
lower the trains slightly, perhaps by loading them up with ballast.

In any case, the train would traverse the tight tunnels at a very low
speed, to minimise sway. I'd have thought that would be enough.

I forgot to mention, the 92 stock on the W&C obviously can't get to
Northfields easily either.

That depends on which part of wikipedia you believe. The text says its wider
but it says 8ft 7in for the width, whereas the width for the 1967 stock was
apparently 8ft 8in. You pays your money....

I suspect only Bombardier and a few test guys really know.

The real question is where do 2009 stock actually get their brakes tested.


At every station. The ATO doesn't mess about, finesse is not part of its
programming



Yes, the Northfields test track is really about testing new brake designs
or materials, particularly in wet conditions. It's not for routine testing
of existing trains.

As the Victoria line is entirely underground, it doesn't need tests in
simulated rainy conditions, so maybe the 2009 stock has no need to be
tested there.

Apart from the depot at Northumberland Park.

Yes, we know — why do you think I worded my comment the way I did?

Really? Surely that would be done in Derby or Japan or somewhere.
