testing...

"Old Dalby will also save 200 nights of testing the trains on the
Underground - time that Metronet will be able to use to carry out
maintenance and improve the track, as well as installing the
signalling that goes hand in hand with the upgrade."

Is this a positive spin off or have they leased the line so they can
catch up on work in the time that would otherwise be needed for train
testing?

Perhaps they will use the time that otherwise would have been used for
train testing for overnight works - but so what! It's a solution to a
problem - or more accurately a response to the issue of scarce time
for engineering works - it means Metronet have 200 nights to do work
on their lines. If it's happening because Metronet are behind schedule
then it'll mean they can claw back some time to do a bit of catching
up. Even if they weren't behind schedule then perhaps it would still
be a good idea (though the economics of it might then be a bit
different, in that it might not be worth it).

Interestingly I recently went for a job interview with Metronet that
might have been involved with some if this - but I didn't get the job.


The Metronet release appears to only refer to the new sub-surface stock.
I wonder if this off site testing is also to avoid interference issues -
or to determine what those issues might be before letting one loose on
the network. The Victoria line - also Metronet new stock - is a self
contained entity but the surface lines are not without connections to
all parts of national rail lines amongst others. Theres a whole host of
issues to be resolved.

The Metropolitan line, is connected to national Surface lines at
Harrow on the Hill, tt's connected to the Circle and H&C at Baker
Street. The Circle is connected to the District. The District is
connected to NR at several points, and is connected to the ELL between
Whitechapel and Aldgate East, and Whitechapel and Shadwell. The
District is connected to the Picaddilly at Acton Town/Ealing Common,
and the Metropolitin is connected at at Rayners Lane.

The Picaddilly is connected to the Central via a link between Ruislip
and Ickenham, it's connected to the the Northern at Kings Cross, and
the Victoria at Finsbury Park.

The Bakerloo and Jubillee are connected at Baker Street, The Bakerloo
is connected to the main line to Watford Junction, and the Jubille
line is connected to the Metropolitan line

Basically you can, assuming you override the signals and points, get a
train from anywhere on the underground network to anywhere else, and
escape on many northern facing tracks (although powering them would be
intereresting, and you'd need careful route planning to avoid any
problem curves)

The exception is the Waterloo and City, which is entirely self-
contained.

Will the Test Track then be joining the select stretches of line with
third and fourth rail electrification plus 25kV overhead, as a fully
featured test track for the UK, or (more probable I guess) will the
overhead be decommissioned ?

I think you'd have to read between the (running?) lines a bit for the answer
to that...

I thought it was interesting, and it corrected any impression of
isolation that some readers might have got from you saying that the
Victoria Line was a "self contained entity". Like all Underground
lines except the W&C, it is connected to at least one other line.

The isolation is more in the sense of trains being confined to a
particular unshared line for normal passenger use, as also occurs with
the Central Line.
