Hugely important to protect alignments and land adjacent to the main routes which could be used for extra tracks.
Particularly important on the Northern line where IR, NTA etc appear to have been asleep on the job and as a consequence infill developments have been allowed to compromise future capacity.
If the height of ambition for heavy rail is to have everything trundling around at 20 mph then the current approach should work well enough although of course passengers travelling much more than 10 to 12 miles will probably do by road other than during periods of intense congestion.
