feeder line
Subsidiary transport route
A feeder line is a secondary route that channels traffic into a main line or system.
In transportation, feeder lines connect smaller communities to major rail corridors or bus routes: The commuter rail serves as a feeder line to the subway.
In utilities, feeder lines distribute power or gas from main transmission lines to local networks.
The term emphasizes the tributary relationship—smaller flows feeding into larger ones.
