"It doesn't need to separate train operations from rail track network maintenance. It doesn't need to open up the network to competition."

This certainly didn't help in the UK. It's been a shameful saga with multiple failures and no clear rationale. The theory was: privatisation -> ??? -> uber efficiency. Ignoring the fact that the economic theory which usually fills in the ??? requires free entry and exit into the market. That doesn't exist in the case of natural monopolies like rail.
