I noticed a 95/96 stock (couldn't tell which) was sitting in northfields

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.

Presumably the signalling there has been immunised against harmonics.
