In this genre, Mini Metro is really fun, highly recommend. https://dinopoloclub.com/games/mini-metro/
One catch is that riders only need to get a particular "shape" of station (roughly analogous to residential, commercial, industrial, stadium, etc). That is to say, they normally don't insist on going to a particular station. Also and it's free in time, money, and political captial to change routes. The model is, I feel, slightly too simple to feel like real transport infra. That doesn't stop it being hella fun though.
