During the administration of then-President Gloria Macapagal Arroyo, a project to rehabilitate the PNR Metro Commuter Line was pursued.

[8] In 2007, the South Korean consortium of Daewoo, Hanjin Heavy Industries and Construction, and Rotem was awarded the contract for the first phase of the Northrail-Southrail Linkage project.

They are currently idle as the North and South Main Line has been closed for the construction of the North-South Commuter Railway.

There were DMUs that sported a silver-colored body and orange lining with white-colored front cabs and the old PNR logo used in the 1960s.

By 2015, all remaining active DMU units sported a navy blue livery, while still maintaining the orange lining in its sides.

The current livery used since 2019 has orange at the front and the body is mostly covered white with blue stripes at the side.

[5] The trains have 2 double-leaf, electro-pneumatically operated sliding doors per side with a width of 1.5 meters (4 ft 11 in).
