The MRTC 3100 class or CRRC Dalian 8MLB LRV is the class of second-generation uni-directional light rail vehicles built in China by CNR Dalian, now CRRC Dalian. Since its delivery, most of the trains are still being tested and undergoing final assessments, before being used on regular services on Line 3 of the Manila Metro Rail Transit System.
These trains are the first LRVs produced by CNR Dalian, which caused some controversy due to compatibility issues raised by MRTC.
The CRRC Dalian 8MLB LRVs are owned by the Philippine government and operated by the Department of Transportation (DOTr).
