What do they mean by "tracks moved"?

Points set wrongly?

Points moved under the train?

Landlide moved the track?

Gradual drift, I expect.

Possibly - but with the intensive service, drivers must have noticed
trains passing unusually closely a long time ago.

Why? Given the intensive service drivers will have all sorts of shifts.
The chance that the same driver will pass another train at that exact point
often enough to think "here's a pattern" would surely be remote. Indeed,
it wouldn't surprise me if depot staff have repaired a few scuffs which
might now be put down to that track problem (but were they really?).

Is the Wimbleware Service especially intensive? Of course it is
entirely possible that the train operators' shifts include turns on
other routes.

The S7 stock is some of the widest to ever operate in the UK. When
Network Rail, or their predecessors, has operated stock with new
kinetic envelope characteristics they have been known to cobble
together a gauging vehicle and move it over the intended routes taking
measurements. Is it within TfL's wit to carry out such an exercise?

You'll probably get the correct answer somewhere in tfl.gov.uk but it
does seem a bit leisurely at times even in the evening rush hour.

Of course it is
entirely possible that the train operators' shifts include turns on
other routes.

The S7 stock is some of the widest to ever operate in the UK. When
Network Rail, or their predecessors, has operated stock with new
kinetic envelope characteristics they have been known to cobble
together a gauging vehicle and move it over the intended routes taking
measurements. Is it within TfL's wit to carry out such an exercise?

It's no wider than other LU surface stock apart from the C-stock.

"D Stock is 9' 4" wide. "S Stock" is 9' 7" wide. While the "S Stock"
is shorter, its kinetic envelope will be different. TfL have also had
problems with the "gap" at some circle line platforms.

As mentioned before, at least TfL know how to make a tube platform
bright and cheeful.

I appreciate you consider the entire organisation to be grossly
incompetent, but yes, LU did do gauging tests for the S7/S8 stock.

That's because of the lower S stock floor height surely? The width issue for
D stock will be the car length and not just the width too. What is the C
stock width?

It is always a mistake to presume to know another's thoughts, and this
is no exception.

I appreciate you consider the entire organisation

No, I am not familiar with the entire organization, only those parts
with which I interface. I knew a mainframe programmer who contracted
for what was then LRT(London Regional Transport)? He was more than
competent. And, clearly whoever nurture's TfL's corporate image does
an excellent job.

to be grossly

One was tempted to counter grossly, and then I remembered the SSL
resignalling. That has been one of TfL's many blunders.

Well that is good to hear.

Wimbleware is, to a certain extent, self-contrained; I went for a 'last
ride' on C-stock a few months ago and got talking to the driver - he hadn't
yet been trained on S-stock, so could only work the Wimbleware turns, at
that time 4 trains of C-stock running daily.

Thank you, there is nothing like first hand information.

Probably, but clearly this should have been tested and resolved prior
to introducing new rolling stock. "S Stock" is widest at waist
height, quite the reverse of the old CO/CP stock.

Much to my surprise C Stock is 9 ft 7 in wide. One lives and learns.
