To go off on a complete tangent does any one know if the 3000 volt 3
phase system the Metropolitan railway considered would have been
straightfoward to install, or would that have required some tunnel
alterations.

So maybe conductor rail electrification was already seen as not the
way to do it back then ? ITYF the cut and cover construction of the
tunnels would at the least have given a more horizontal tunnel roof to
work with.


Don't forget that, in 1900, the percentage of the Underground (as
distinct from Tube) lines that were in tunnel was very small indeed.

The cut and cover tunnels were constructed on an ad hoc basis to allow
buildings to be constructed above, in a way comparable to the Gerrards
Cross Tesco project.
