The PNR 900 class is a class of 21 GE Universal Series diesel–electric locomotives operated by the Philippine National Railways since 1973. The locomotives comes with three different types: U14CP (1973), U14C (1979), and U15C (1991). Initially used for long-distance express services throughout Luzon, they were relegated to hauling commuter trains within Metro Manila, a task previously done by PNR's diesel multiple units fleet. This was further exacerbated by the closure of the PNR South Main Line's intercity section in 2012 after an accident in Sariaya, Quezon.[7]
