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

I always thought the Tube was electrically operated?

Last time I looked a battery loco carried its own electricity.

And what happened to the abandoned rolling stock? Evaporated?

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