At Brixton and Walthamstow Central stations there are no buffers, but the
track appears to wander into the distance.
At brixton there appears to be a curve.

Where do these tracks go?
How long is the length of the exess at Brixton and Walthamstow?

It would appear that there is space to stable a train in both roads at both
ends of the line and the pit road could enable a fitter to work under a
train as well.

In essence there are lengths of track that run on beyond the normal ends
of the platforms at both Brixton and Walthamstow. There are protective
signals / switch points to stop a train in the overrun tunnels reaching
the normal platform areas.

Where it says "pit" then there is a sunken area under the rails which
would allow access for a train technician / fitter to the underside of
the trains.

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.

I think the telephone symbols indicate the existence of a signal post
telephone which the driver could use to speak to the line controller.

There certainly used to be a scheduled move into and out of the tunnels
at Walthamstow as I used to catch a train that came out of the overrun.
It was novel watching people's faces when a train arrived from a
completely unexpected direction. If trains become defective but can
still be moved then sometimes they will be shoved into the overrun
tunnel until such time as it is easier and less disruptive to take the
train back to Seven Sisters to get into Northumberland Park depot. I
understand engineer's trains have been parked in Victoria and Brixton
sidings in recent days.

The line continues beyond the platform ends at both terminii for two
reasons. During normal service hours they provide an over-run so that if
for any reason the normal stopping and safety procedures fail, trains
don't immediately run into a solid wall.

But their main purpose, certainly at Brixton (where the over-run tunnels
are 1200 feet in length) is to provide over-night stabling for trains so
that the service can begin with a reasonably frequent service in the
early morning without having to wait for trains to make their way from
the Northumberland Park depot.

The final "Badger Railtours" trip we ran a few years back ("The darker
side of touring") ran into the tunnels at both ends as well as many
zany crossovers, the depot at Northumbeland Park and the reversing
sidings at Kings Cross and Victoria.

I believe that the BLS or someone similar did one also ?

It would prevent all sorts of overnight engineering work being
undertaken - either on the tracks, posting of posters or working at
heights on the platform or close to the edge - such as cleaning signage,
adjusting CCTV cameras or replacing lights. Much more sensible to stick
the trains up the tunnels out of the way.

The over-run tunnels will increase the potential stabling capacity
from two trains to four but if a train is left in the platform then
that platform would not be available for reversing any trains (or, if
both platforms, that end of the line), which could include night-time
engineering trains.

I assume it also obviates the need for TETS (aka Moorgate control),
which would require trains to slow to 10mph on approach to the
platform.

This saves time - particularly important on the Vic with its very
tight turnarounds, which include stepping back.

(Explanations of TETS and stepping back shouldn't be hard to find with
a quick search.)

Although Moorgate control was unheard of when the Victoria Line was

Could this be true? As far as I know there are still two sidings there
as well.

I had an idea that they stabled trains in the platforms at Elephant and
Castle on the Bakerloo, which has a similar layout, but I note from
Quail that there are sidings there as well which, unlike those at
Brixton, are connected to each other.

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.

The surface lines have triangular junctions at Earls Court and Aldgate, as
well as Moor Park/ Rickmansworth/Croxley. The Northern Line has a reversing
loop at Kennington. Piccadilly Line reverse by running around the loop at
Heathrow. Central Line can turn by running right round the Hainault Loop.

But you can't necessarily couple the north end of one train to the south end
of another identical train, unless the original trains were facing the same
way as each other.

There are no such facilities in depots. The two obvious triangular junctions
which can turn a train are visible on the tube map near Gloucester Road and
Aldgate. There is a non-obvious one linking Moor Park, Croxley and
Rickmansworth. The two obvious loops for turning trains are shown on the map
at Heathrow and Leytonstone-Hainault-Woodford, and the non-obvious one is at
Kennington, allowing trains from Goodge Street to head back to Goodge Street
without reversing. Trains cannot be turned on the Bakerloo, Victoria,
Jubilee, or East London Line without a significant trip on another line, and
trains cannot be turned on the Waterloo & City without being lifted by
crane.

I think more of it tends to be able to couple both ways nowadays. The
C stock on Hammersmith, Circle and Edgware Road lines always could, for
obvious reasons. The A stock on the Metropolitan could as well
(although now many units only have the driving equipment at one end),
for less obvious reasons. I suppose because of Watford.

The CO/CP/COP stock could only couple one way, and did sometimes run on
the Circle till C stock took over the Edgware Road branch. They
managed to get it back to the District Line facing the right way.

The Northern Line stock could only couple in one direction but, because
of Kennington, half the units could never couple to the other half.
They seemed to cope somehow. The same on the Picadilly after Terminal
4 was opened.

I remember the 1962 stock on the Central always facing the right way
for years, despite the obvious loop. Maybe anything that went in the
depot from the Grange Hill end always left that way, but then one year
in the 1980s or so they seemed to stop bothering and it ended up fairly
random.

Given that all BR and some Underground stock had universal couplers, I
never understood by the Underground gave itself the problem of
couplings that had to face the right way.



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

There's no dedicated stock for the Circle anyway. Also, even on a
non-circular line like the Central, that would mean that the north side
got more worn out, because of the way it bends and so on. I wonder if
it's really a problem?

A few 3-car sets of Piccadilly stock were built with cabs at both ends, so
thatb they could substitute for either half of a 6-car train formed of two
unidirectional half-sets. A 3-car set was also needed for the Aldwych
branch.

For many years Woodford to Hainault was treated as a branch, with a service
entirely separate from the main Central Line service. Trains from the
Epping/Hainault - Ealing Broadway/West Ruislip service, if they went to
Hainault depot, always went via Newbury Park. Woodford - Hainault was used
for trials of the Victoria Line automatic operating system.

Long before there were through trains to Woodford via Newbury Park and
Hainault, there were always through peak services starting or ending at
Grange Hill via Woodford. I've always assumed that the reason for this
was that they went in and out of service at Hainault Depot at the
Grange Hil end without all having to go via Newbury Park (Woodford and
South Woodford probably had more punters than the rest of the line to
Epping).

Whether or not it can, the Metropolitan Line working timetables take
care to keep trains the same way round. When a train stables at night at
Rickmansworth after coming from Watford, the same train goes via Watford
in the morning. [By "same train", I mean that if the former stables in
siding 26N, then the first working from 26N will run via Watford.]

There are also some "train turning" conditional paths, running
Neasden-Watford-Ricky-Neasden (or the other way round).

With modern LU stock it usually doesn't matter too much which way
round they are while running but where the units are the "wrong way
round" it can result in some (not all?) of them not matching
pre-positioned equipment in workshops, forcing additional ECS workings
to turn them; ISTR that (before "rusty-rail" movements were as common
as nowadays) such workings were occasionally the trigger for points
and track-circuit failures which paralysed services.

I'm surprised to hear that so called "rusty-rail" movements were less
common in the past - it just sounds like fairly good common sense to
me. Whilst I can see the 'bean-counters' potentially objecting to what
they might see as frivolous manoeuvres, if said manourvres demonstrably
improve operation and prevent failiures (or at least provide an early
pointer to upcoming problems) then they can only be - and be seen to be
- a good thing.

ICBW but ISTR rusty rail movements as a deliberate precautionary
policy being a 1970s introduction, quite possibly encouraged by the
bean-counters. In many cases it merely involves ensuring that
movements use all available routes through a particular area so is
effectively "free" in those cases.

It was a problem with the introduction of automatic couplers. The
original (1938) designs didn't have enough contacts to duplicate
connections so they could couple both ways round. Previous District
mechanical Ward couplers were handed, IIRC.

And they would have to be the first trains into service, although that
probably isn't a problem.

In the last couple of years, the whole of the central section was
closed due to a problem at the bottom end and, being sure that there
are also two sidings at Victoria, I asked why they couldn't turn round
at Victoria. An LU person told me that they couldn't turn round at
Victoria any more.

Could this be true? As far as I know there are still two sidings there
as well.


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...

Also, even on a
non-circular line like the Central, that would mean that the north side
got more worn out, because of the way it bends and so on. I wonder if
it's really a problem?


Unbalanced wheel wear was seen as a potential problem for the
Eurotunnel shuttles, which is why the turning loop at the French end
has the opposite sense to the one at Folkestone. Whether that was
based on actual evidence I don't know.

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.

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
crane.


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.
