Well they can also generate revenue by advertisement. plus property rate around station will going to be high (it will be great impact on money rotation)

more people traveling in train instead of personal car will also reduce co2 in air which is eco friendly too.

less traffic means there is a wide and safe road for bicycle rider and people who like to walk.

one big benefit of travel throw train is time. you can be on place on estimated time. due to less traffic.

All my comments are based on my experience, I am traveling throw train for work, here in tokyo.

Advertising revenue is insignificant compared to fare revenue.

I edited my response, sorry I did not see your response before, but my point it is not always about money.

Ask that to Bangkok BTS system. Fare revenue is roughly equals to advertising revenue.
