> It's important to note that no train system in the world is covered by fairs. They are always subsidized by the state. In most cities, fairs make up 20% ~ 30% of costs (tolls are about the same for toll roads). This is demonstrably false. There are plenty of systems where fares make up close to 100% (or even exceed 100%) of their costs with fares: https://people.hofstra.edu/geotrans/eng/gallery/Map_World%20Farebox%20Ratio.pdf https://people.hofstra.edu/geotrans/eng/gallery/Map_World%20...
