In the depot. The first thing you'd have done is cleared the running
tracks.

Without traction power? And who would clear the rolling stock, precisely?
The Royal Household?

It used to be a sackable offence to leave any train standing on a line
BR or LT, so unless rules have changed, all trains will have a driver on
board and the depot is most likely to be where their car is to get home.

But an electric train stranded out the line with no power is not going to go
anywhere, whatever the signals say.

And quite probably because there is no traction supply there will be no
supply for the signals either. Also most underground lines also rely on
compressed air to operate the trainstops and point machines. All these
supplies come from substations dotted along the line. No supply in = no
supply out. Most if not all stations now have a UPS back up system to
supply lighting CCTV and PA systems for about 1 hour. After that runs
down, complete and utter blackness.

Why should it have no power? If all the electrical staff deserted, as
long as they didn't throw any switches, juice would still be on
throughout the network.

Can you explain why the many references to battery locos have escaped
your attention?

That would have been done long before, when the lines were shut to the
public.

Not all the rolling stock is battery operated, is it? I was referring to the
everyday clutter of hundreds of trains using the system.

You see, I think you have in mind some sort of orderly gradual transition
from normality to emergency, when the government announces a problem and TfL
responds by ordering all the LT staff to clear the system of rolling stock,
and generally closes it all down neatly.

I on the other hand don't think that any emergency likely to cause it
necessary to make an emergency covert evacuation of VIPS from London is
going to happen in such a way. Whether a missile strike, a dirty bomb or a
germ scare, the transition time is likely to be extremely short, either
minutes or a couple of hours, and tidying all the trains away to their
depots is simply not going to be a priority either for TfL or LT staff -
most of the latter will have other priorities. It might happen, of course,
but the strong likelihood is that it won't, and the system will be abandoned
in some state of disorder.

This being the case, no sensible planner is going to choose the Tube as a
route for VIP emergency evacuation: there is only a slim possibility that it
could be so used, and there are far more reliable methods available.

Incidentally, while LT is rightly proud of the transport continuity provided
in some areas of London during the Blitz, in the East End a very large
number of station staff, bus and train drivers and conductors abandoned
their posts under fire. That sort of precedent suggests continuity of public
transport service in London in an sudden-onset acute emergency cannot be
expected.

A good example of this was 7/7. Trains were abandoned all over the
network. It was a day or two before they'd all been rounded up and put
in their respective depots.

Gradual enough, yes.

Not much use in using battery loco's or any other type of loco's if you have
passenger trains on the main line that cannot move because of no power being
available. How long will it take for a small number of battery loco's to
drag thesse abandond trains out of the way?

And who would clear the rolling stock, precisely? The Royal Household?

How?
