rail system

A rail system, or railway, is a transportation network that uses trains running on fixed steel tracks to move people or goods efficiently over long distances. Tracks are made of parallel rails laid on a bed of gravel, providing stability and smooth movement. Trains consist of connected cars powered by electricity, diesel, or other means, and follow designated routes controlled by signals and switches for safety. Rail systems are vital for freight and passenger transport, offering energy-efficient, reliable, and high-capacity travel options, especially for heavy or bulk cargo across cities, regions, and countries.
