A metro system that is part of the National Rail network seems to work
perfectly well in Liverpool. Are there reasons why it wouldn't in London?

But its not a metro system is it. Its just a load of old BR track lumped
together and rebranded as a metro. You could do the same to half a dozen
different suburban lines in cities around the country.

It didn't seem much different in practice to the Tyne & Wear metro (the only
other one I'm familiar with) - a similar proportion of it is undeground.

And since when was the whole of the London Underground designed as one metro
system? My knowledge is patchy but I know most of the eastern end of the
Central Line was BR track until 1945 or thereabouts.
