Light Rail Transit

Extracted from the Wikipedia article Light rail.
Narrowly defined, light rail transit uses rolling stock that is similar to that of a traditional tram, while operating at a higher capacity and speed, often on an exclusive right-of-way. In broader usage, light rail transit can include tram-like operations mostly on streets. Some light rail networks have characteristics closer to rapid transit. Only when these systems are fully grade-separated, they are referred to as light metros or light rail rapid transit (LRRT).
