Aylesbury to Claydon has booked trains (binliners), and because of the low
speed and long block section the binliners wouldn't actually leave a lot
of time for testing.

During the morning the section from Claydon to Calvert is used by arriving
and departing Avon binliner. The Cricklewood binliner then arrives in
section at 13:40, running down to Calvert where it is then locked in the
loop, where it remains until early evening. The Dagenham Dock binliner
follows it down from Aylesbury at 16:40. Things then start getting very
busy: the Cricklewood empties then return, followed by the Ripple Lane
empties, then the Northolt West Waste binliner runs down and returns almost
immediately. By that time it is approaching 01:00!

In addition to those there are the rarely used test train paths for class
16x testing, the 5T00 09:40 and 10:20 Aylesbury to Claydon and 5T01 11:20
and 12:05 Claydon to Aylesbury paths.

So, quite apart from the infrastructure impracticalities, it would be a
complete non-starter.

Anyway , why would district stock ever run through to tilbury anyway?

1910 - 1939 there were through trains between Ealing Broadway and Southend,
electric-hauled over the District between Ealing Broadway and Barking, and
changing engines there.

Short clerestory roofed electric engines that had the same profile as
the District's EMUs.

Presumably on a test line it is relatively straightforward to set up
the safety case in such a way that the rails are switched off an
earthed down before anyone goes out onto the track.
That would tend to suggest driverless trains. Or if one breaks down
on the test track, a very long wait for the driver to be "rescued".

Surely on a test facility there will be people on the ground monitoring
and controlling things? It can't be that hard for the driver to radio
control, tell them he's broken down or needs to get off, and have them
turn the current off. Wouldn't work to run a mainline railway like
that, but I can't see it being such a problem for a test track.

Turning off perhaps, but earthing it down might take a little longer.

How about the SCDs in all the cabs?

Bootstrapping problem! If it's too dangerous to be out on the track
because it's 3rd/4th rail, then surely it's too dangerous to be out on
the track with an SCD - even though that's in order to make it more
safe.

(I'm assuming here that existing 3rd/4th rail tracks have grandfather
rights regarding this issue, and of course that the issue is a real one
in the first place, rather than just a rumour).

Long clerestory-windowed Christian churches, i've heard of; how does a
clerestory roof work?

A raised centre section to the roof, in the side of which may be either
glass windows or sometimes ventilator louvres. They were a common feature of
19th century carriage design.- perhaps as a means of 'borrowing' light for
the middle of compartments.

What for?

I'll throw that one back at you and ask ''why not''. The Bakerloo goes
to Harrow (and used to go to Watford), the ELLX is projecting LU service
over NR routes, Croxley link (if ever) are examples.

Its being designed for the tube system

Actually, no its not.

S-stock does NOT run in the tubes but on the sub-surface lines.

not national rail.
Different radio
systems, different ATP systems

So what ?

Stop looking at details and think about the bigger picture.

, possibly a slightly different loading
gauge,. not to mention
the 4th rail shoes dangling inbetween the rails that could foul some
mainline track systems.

So 4th rail surface trains are out of gauge at Wimbledon and Richmond
are they ? Met A stock knocks NR infrasture to pieces every time one
goes to Amersham ?

S-stock is being built as common stock for all sub-surface lines. I'd be
pretty sure that spec would more or less put them within NR gauge.



Anyway , why would district stock ever run through to tilbury anyway?

I actually said Tilbury lines not Tilbury i.e. the LTS or C2C routes.

And - as been pointed out already - District trains did used to run
further than then they do now to beyond Upminster.


There was so much negative thinking in your response. If everything
proposed was dealt with your way nothing would ever move forward. It was
that type of thinking that leads to the ''we don't want air brakes
because we've already got vacuum brakes'', ''we've already got paraffin
tail lamps what do we need electric lamps for'' and ''BedPan and
Blackfriars work perfectly well what do we need Thameslink for''
brigade. We'd still be running unbraked open trucks with men waving red
flags in front of them.
