High Quality Content by WIKIPEDIA articles! The Manila Light Rail Transit System, popularly known as the LRT, is a metropolitan rail system serving the Metro Manila area in the Philippines. Although referred to as a light rail system because it originally used light rail vehicles, it has many characteristics of a rapid transit (metro) system, such as high passenger throughput and exclusive right-of-way. The LRT is operated by the Light Rail Transit Authority (LRTA), a government-owned and controlled corporation under the authority of the Department of Transportation and Communications (DOTC). Along with the Manila Metro Rail Transit System (MRT-3, also called the Blue Line), and the Philippine National Railways (PNR), the LRT is part of Metro Manila`s rail transportation infrastructure known as the Strong Republic Transit System (SRTS).
