Design train tracks and stations with the simplicity of a grid and tiles, but the flowing shape of curved tracks. By alternating straight and curved sections of track, you can quickly and intuitively control the track layout.

Connect industries with trains to carry resources and deliver products to cities. Beyond the basic raw materials, most industries accept secondary or tertiary inputs that can boost production.

Optimize your solutions and compare with other people on a global leaderboard. You can iterate on solutions by making changes then running at 1000x speed to see the results. Or, run at normal speed and bask in the glory of your creation.
