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, two (2) locomotives are active in revenue service, 5001 is assigned as Caloocan shunter, 5009 is assigned in the Bicol Commuter Line while 5007 is in Manila.

Three units followed suit in being repainted into the orange livery with the 900 class and 2500 class locomotives.

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]

Features

The 5000 class or the GE U6B units feature number signs when they arrived in 1992, which are also found on the last batch of the 900 Class which consists of the U15C units.

The shorthood side of the locomotives has its door on the middle of the driver's cab. Which is different from the 900 class where it has its door on its left side.
