Indeed. It will have been closed for normal traffic for some time. Which
is why it's easily available for various (not just Royal Family) special
operations.

But in any sort of mass attack, the Tubes are going to be paralysed by (a)
general panic; (b) absenteeism of key workers; (c) breakdown of supporting
infrastructure (communications, signalling, electricity) consequent on the
foregoing.

Assuming that the network will be lying empty but functional seems very
naive.

It only needs to be functioning enough to handle one battery loco and a
carriage. No signals required.
