Passengers are a transportable thing in Train Fever. They have a starting location at a residential building and a final destination at either a shop, work or leisure building. A destination will be chosen at random with a weighting towards closer locations. If the destination is reachable within a 20 minute travel window then either a pedestrian or a car will be generated and will take the quickest possible path to that destination.

Passengers can only be transported from a selection of station types which can be selected in the station construction menu of either road or rail. Passengers also require appropriate vehicles which have a passenger capacity.
