Most railways are far too narrow to 'convert' into roads - the cost would
be horrendous. Would make decent cycle tracks, but I doubt that would
appeal to you. ;-)

Well I don't know.

I read somewhere that somebody had done the sums for the Paddington
main line (4 tracks essentially) and worked out that with train
occupancy and spacing between trains because of signalling, it would be
possible to substantially increase throughput of people by tarmacing
the route and having car use.
