reason to close it. Any materials for the extension that need to be
moved by rail could be done at night.

It does seem a long time, especially considering it was closed for
several years not that long ago. It can't be in that much of a bad state

I noticed on Clive's line guides, that after the last closure, the power
supply was made switchable between third or fourth rail mode. Which seems to
be another reason to question the length of closure.

The NL and DC lines were converted from 4-rail to 3-rail with no
special closure period, presumably being done during succeeding
Sundays on one sub-station at a time.

I'm somewhat surprised at that; AFAIK (and I used to draw the power
supply diagrams which the controller used) the ELL was no different
from any other tube line. It wouldn't be the first inaccuracy from
Clive when it comes to detail (and in the rail industry, the devil
really is the detail).

Certainly the signalling was not compatible with a third rail power
supply.
