Metro Manila Railway System Line 4 will begin construction in 2026🇵🇭🚉
Construction for the Metro Rail Transit Line 4 (MRT-4) is anticipated to start in 2026, following preparatory work like detailed engineering design, with funding secured from the Asian Development Bank (ADB), aiming to connect Taytay, Rizal, to the EDSA-Ortigas junction and significantly ease traffic in eastern Metro Manila.
So, while there are 3-4 lines now, Manila is heavily investing in adding at least 4-5 more major lines (Subway, MRT-7) and planning others, aiming for a much more extensive system.
