The railway system in the Netherlands is not privatized. The structure is publicly owned but operated under a concession model where both state-owned and private companies may run services. There are some regional operators that are private companies, but by far the largest part, NS and Pro-rail, are wholly government owned.

I'm not in favor of privatizing a natural monopoly like railway infrastructure, but in the case of NS I'm not sure privatization would be worse than what we have now: "market friendly" salaries for management, and yearly losses go to the tax payer.
