At Walthamstow the tunnels run for a considerable distance - I
understand that they almost reach to Wood Street station but I don't
know how close to the surface they reach or whether the remain at the
same depth as at Walthamstow Central. I don't know how far they go
beyond Brixton station.

Using the standard "km from Ongar" scale:

Walthamstow station 27.33
Walthamstow tunnel end 26.98

Brixton station 48.61
Brixton tunnel end 49.02

The station locations will be the midpoint of the platforms, so assuming
a station length of 140m, that gives tunnel lengths of 280m and 360m.

There are two sidings at Victoria and one at King's Cross. It's not
uncommon for trains to terminate at the former and reverse, and I think
(although I'd have to check the WTT) that there is one train a day
scheduled to use both. Late evening if I recall correctly...

On TfL's ETA site for the Victoria line I have seen a train destination
of 'Walthamstow Sidings' - as opposed to 'Walthamstow Central' for a
normal terminating train returning south.

trains cannot be turned on the Waterloo & City without being lifted by

Although there is (well, was 10 years ago) a turntable in the depot, but
not big enough for a whole carriage.

What's the point of that, then?

It's cheaper to leave a turntable that was big enough to turn
previous stock around in place than rip it out?

However, ISTR that it was removed during the closure... but you'd
be foolish to rely on my memory.

This got me thinking literally, "are there any depots or
strategically-placed triangular junctions at which a train could be turned
right round?"

LU trains are not, as far as I know, biased to be driven from one end or the
other, but I could see circumstances such as the Circle Line where it could
be an advantage to turn a train to even out wear on the wheels.

I don't know whether some variant of it still runs, but there used to
be a train in the inner rail Circle service which stood for a while at
Edgware Road after the evening peak then renumbered into the
Hammersmith & City sequence, continued inner rail to Tower Hill and
then ran via Aldgate East. I did not know how physical sets were
allocated to train numbers so don't know if there was a pattern to
ensure sets were turned or if they were chosen on a "need" basis by
depot staff.

Cheers,
John

Is the 92TS so much longer, if at all, than previous stocks?

The turntable was a for coal wagons when the line had a coal fired power
station, the wagons cam down on a separate lift.

I can just just about believe you might need to turn coal wagons
round, if the coal has to be tipped out of one end... but I can't
believe said power station would need the coal to be delivered
along the Drain!

Have I missed something, or are you winding us up?

Surely just for local heating in the depot? we tend to forget nowadays
just how much infrastructure there was for delivering coal to domestic
and business properties until about 40 years ago or less.
