Why Is Your Factorio Train Stopping For No Reason? The Signal Mystery
New blueprint chains and signal updates push players to rethink rail logic. That makes this puzzle feel fresh again. This topic helps you spot why trains halt unexpectedly.
Why Is Your Factorio Train Stopping For No Reason? The Signal Mystery is a logic issue where signal rules block loading. Trains wait because circuit conditions treat full or empty conditions as red.
How Signals Actually Control Rails
Combinators read train cargo and change signal output. Trains only move when conditions match green signals at the next station. Research shows simple arithmetic patterns prevent most confusing stops.
Arithmetic checks and signal planning keep your network reliable. A clear signal layout keeps automation smooth.
Quick Insight
Signals act as rules for train loading and path safety. Clear conditions let trains run without manual babysitting.
Why does my train ignore green signals?
Signals might be set to stop or rotated wrong. Check signal directions and circuit inputs.
How do I test my signal logic?
Use combinators to print values. Read logs to see when conditions switch red.
