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.
I figure all the triangle stations must have well-connected bus routes going to the same area, and so on down the shapes. I mean surely you're not responsible for building an entire transit system!
It’s obvious in hindsight, but before I lived in the Boston area I never appreciated just how critical it is to have buses to supplement a subway, subway & buses to supplement light rail.
Whenever the idea of light rail came up in my hometown, I would point out to my enthusiastic friends that without a better bus system, there’s not much point to rail.
My suburb has solid light rail to the city but a poor bus system to complement it. My closest bus doesn't run at all on weekends. There is a huge park and ride lot but, since I'm already in my car driving towards my destination, it always ends up being a question of whether I want to deal with a rail ride that might be equivalent to driving inbound but will be at least 30 minutes longer on the return. The deciding factor tends to come down to parking costs in the city or whether I plan to drink and need the long return ride to sober up.
