China high speed rail growth over 9 years. It's an excellent system and I much prefer it to domestic aviation.

See people in here talk about land area and population while completely ignoring things like topography/zoning/protectionism. Building 100km of rail in Switzerland is never going to be comparable to building 100km on flat plains elsewhere.
Of course, Beijing-Shanghai line is the first and only to go public, just at the beginning of 2020, and we can get their financial numnbers easily.
Many other lines are not necesarrily profitable, but few of them require government subsidy besides the initial capital investment, that is their income is more than the operational cost.
