what is a light rail

Light rail is a type of urban passenger train system that usually uses lighter vehicles than heavy rail or subways and often runs on electric power from overhead wires. It usually carries fewer passengers than a metro, but it can move faster and serve more distance than a streetcar in many cities.

Quick Scoop

• Light rail vehicles are typically electric and run on fixed rails.

• They may travel on dedicated tracks, in mixed traffic, or a mix of both.

• Compared with a subway or heavy rail line, light rail is generally smaller, less separated from the street, and built for medium passenger demand.

• Compared with a tram or streetcar, light rail often has longer routes, higher speeds, and more separated right-of-way.

Simple example

A city might use light rail to connect downtown with neighborhoods, shopping centers, or a nearby suburb. That makes it useful when bus service is too slow and a full subway would be too expensive or unnecessary.

TL;DR

Light rail is basically a middle ground between a streetcar and a subway: rail-based, usually electric, and designed for urban travel with moderate passenger volumes.
