> The trains don't make money
This is untrue. From here: https://en.wikipedia.org/wiki/Farebox_recovery_ratio
... look at all the entries in Japan where ratio >= 100%. It is a lot. This one is bonkers to me (JR Central Rail: 245.95%), but easily explained by owning and operating one of the busiest bullet train routes in the world between Tokyo and Osaka.And, this does not include all of the (profitable) real estate projects these companies use to further increase ridership!
Well, I stand corrected!
However, it may not include the real estate income, but it does include the income from extra ridership created by the real estate being near the station.
It's true, the bullet train prints money for JR. But there are also many train companies that are only profitable because of their real estate holdings around the lines, especially smaller private companies like Tokyu.

Page 296: Farebox recovery (%), 2005 125.3 (Tokyu Corporation’s entire network)
After the opening of the last Tokyo Metro line (Fukutoshin) -- with direct connection to Tokyu Toyoko line (Shibuya to Yokohama), the farebox recovery is surely much higher. I guess over 150%, but probably closer to 175%. The trains are jammed 8+ hours per day. This means that, excluding real estate development, the Tokyu train lines are profitable by themselves.
About Tokyu: "[S]maller"? Absolutely not. It is surely one of the top 5 largest private rail companies in Japan by revenue/profits. They are huge in the Tokyo area.EDIT -- Re-org only.
