Definition

Noun: A secondary railway line that connects to and diverges from a main railway line (trunk line). It serves local areas, industries, or specific destinations not on the main route.

Usage

A "branch line" is a specific type of railway infrastructure. It is used to describe a less important line that splits off from a primary, high-capacity trunk line. Its primary function is to provide connectivity to smaller communities, factories, mines, or ports, feeding traffic onto the main network.

  • Freight trains use the branch line to transport goods from the factory to the main rail network.
  • The railway company is considering reopening the branch line for tourist services.

Advanced Usage
