Which isn't going to revert anytime soon.
In safety hazard terms, 26 miles of single track and 18 miles of double track is not short, especially;
a) where access to the public and animals is difficult to restrict
b) where the hazard is new and habits of the general public may be difficult to break, (the public's knowledge of the hazard and casual attitude to 3rd rail has been mentioned more than once ibn this thread alone.
You clearly
don't know what I believe. 3rd rail is already in some decline, both in terms of route miles (reduction on ther NLL), and traffic expansion (caused by the limitations of veery high current demands on a low voltage supply). And no I don't fantasize about anything on the railway, - it is there to do a job, reliably, environmentally sustainably and above all safely.
As has been posted many times here before, much of the infrastructure on the third rail railway has been around for over 100 years, partly because the expedient of using a cheap electrification system was widely continued until theose responsible for safety virtually halted it. Replacing worn-out or obsolete equipment on an electric railway is not a 'second electrification'. OLE kit also wears out, (although nowhere near as fast as 3rd rail kit) so replacing it isn't considered as a second electrification. In the future parts of the '60s & '70s WCML of even the '70s & '80s cheapo MKIIIb OLE on the ECML will need replacing (which would probably include upgrading to modern hardware like Master Series), and I'm sure that the most 'embittered tribalists'* from the north would not see that as an 'improvement' to their railway, except in terms of fewer dewirements.
