Why Your Factorio Factory Fails: The Shocking Truth About 3-Lane Flow

Modular layouts and fast belts drive curiosity. Players experiment, then hit mysterious traffic jams.

Why Your Factorio Factory Fails: The Shocking Truth About 3-Lane Flow is a bottleneck pattern. It arranges three parallel lanes to balance throughput against control. Why Your Factorio Factory Fails: The Shocking Truth About 3-Lane Flow describes alternating input lanes. Research shows this design stabilizes flow at busy intersections.

Bottlenecks appear when signals mismanage merge points. Constant switching from one side blocks the middle lane. Studies indicate straight lanes handle higher volume when lanes stay dedicated.

This setup helps late game factory growth. Players see higher items per minute with clear path separation.

Why does spacing matter here?

Spacing prevents merged lanes from colliding. Good gaps keep items flowing smoothly.

When should you switch belts?

Switch only when lanes split to different machines. Keep merge zones short and well signaled.
