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. |
