The Metro Rail Transit is Metro Manila's third rapid transit line. It forms part of the Strong Republic Transit System, which includes the Manila Light Rail Transit System. The line operates under the name Metrostar Express and is colored blue on rail maps.
The line is located along the Epifanio de los Santos Avenue, one of Metro Manila's main thoroughfares. It has thirteen stations along its 16.95km track which passes through the cities of Makati, Mandaluyong, Pasay, Quezon City, and San Juan. While originally intended to decongest , the MRT has been only partially successful in decongesting, and congestion is further aggravated by the rising number of motor vehicles.The expansion of the system to cover the entire stretch of EDSA is expected to contribute to current attempts to decongest the thoroughfare and to cut travel times.
Opened in 1999, the MRT is operated by the Metro Rail Transit Corporation , a private company operating in partnership with the Department of Transportation and Communications under a Build-Operate Transfer agreement. Although it has characteristics of light rail, such as the type of rolling stock used, it is more akin to a rapid transit system.
