Players may buy more buses (they start off with one) build onto their bus route bring new passengers to the city (via the trains) expand the city by adding more buildings and run their buses. There is another option the clock. The action board has one other clever feature. On some actions route expansion and building the first player to choose that action actually gets to execute the action last! Which leads to some interesting games of chicken and some painful decisions.

Buying more buses allows a player to carry one more passenger every time they run their buses - hence scoring in the best case one more point. Depending on how the city gets built however finding lots of passengers on the street can be tricky.

Bus routes extend from either end of a Settlers-style initial placement. Extensions are appended to either end. Routes may only run parallel if there are no empty streets at one of the ends or the line ends on the crossing as another player's end. All new passengers will arrive at one of two train stations so that is one concern when route building. One must also be careful to run by a nice mix of building types. And when building one must always have an eye towards spoiling other players' routes by placing a mix of building types at each of their intersection so that all of their passengers just walk! Finally when carrying passengers one wants to be careful to set up to carry the same passenger next turn.
