The first use of the Scharfenberg coupler was for the Manila MRT Line 3 in 1999. Meanwhile, the first use of the Shibata coupler was for the LRT Line 2. In the future, Shibata couplers are also expected for use on the MRT Line 7, the Metro Manila Subway, and the North–South Commuter Railway (NSCR). The NSCR is so far the only PNR line that ...
