The MRTC 3000 class, also known as the Tatra RT8D5M, is the class of first-generation high-floor uni-directional light rail vehicles in use on the Manila MRT Line 3 and built by Czech tram manufacturer ČKD Tatra. The LRVs are owned and operated by the Department of Transportation (DOTr).
Until 2025, the RT8D5M LRVs were owned by the Metro Rail Transit Corporation (MRTC) pursuant to its build-lease-transfer contract with the DOTr. These were also the last vehicles made by ČKD Tatra before it was taken over by Siemens.
