INTERCHANGE

You draw a line between two stations. A train appears on it and starts running. That is the only verb in this game.

Passengers have colors. Put a red one and a blue one in the same train and they arrive as purple. Purple buildings exist and are waiting, but purple passengers spawn nowhere. Your network is the only thing that makes them, and that single rule turns a transport game into a production game.

The city keeps growing. New stations appear every week, platforms fill up, and a platform that stays full ends the run. At the end of each week you pick one of two cards: a bridge across the water, an extra line, a station that merges passengers while they wait.

This is an early build, made for testing. It is not finished and it will change.
