The city is serviced by LRT Line 1 (LRT-1) and Line 2 (LRT-2), which form the Light Rail Transit. Development of the railway system began in the 1970s under the presidency of Ferdinand Marcos, when the LRT Line 1 was built, making it the first light rail transport in Southeast Asia, though despite the name "light rail", LRT-1 operates as a light metro running on dedicated right-of-way. LRT 2 on the other hand, operates as a full-metro heavy rail system. These systems are undergoing a multibillion-dollar expansion. The LRT runs along the length of Taft Avenue (N170/R-2) and Rizal Avenue (N150/R-9), while LRT-2 runs along Claro M. Recto Avenue (N145/C-1) and Ramon Magsaysay Boulevard (N180/R-6) from Santa Cruz, through Quezon City, up to Masinag in Antipolo, Rizal.
