Operational history

The 5000 class locomotives were acquired in 1992[4] to haul dead-motor CMC diesel multiple units. These were eventually used to haul passenger coaches in the PNR Metro Commuter Line. Currently, three locomotives are active, 5001 is assigned as Caloocan Workshops shunter, 5009 is assigned in the Bicol Commuter Line while 5007 is in Lucena

Two locomotives, DEL 5001 and DEL 5007 is repainted into an orange livery, to follow suit with some 900 class and 2500 class locomotives being repainted in the orange livery.[6]

Specifications

The 5000 class locomotive has a length of 11 meters (37 ft), a width of 2.7 meters (9 ft), and a height of 3.7 meters (12 ft). It is powered by an 8-cylinder Caterpillar D379 engine, with an equipped GE GT751 main generator and GE GY27 auxiliary generator.[2][5]
