In some corridors, that's true. But we currently have rail companies that fight tooth and nail to prevent passenger rail from existing.
Personally, I'd love to see the post office running freight rail for the country, investing in electrification of rail, and focusing on moving as much freight as possible by train.
It's the opposite problem in Sweden. Priority is given to passenger trains and freigh suffers. They are locked in to decisions made decades ago (for example, single not double tracks in most places) and expanding the tracks is extremely costly and extremely slow (the bane of any modern development).
