Purchase

The trains are manufactured by Hyundai Rotem, and the electric products were made by Toshiba. A total of 72 cars were produced between 2002 and 2003 to service in Line 2.[6]

Design

Exterior

The car body is made of stainless steel, and the under frame shares the similar material with LAHT steel.

The trains sport a livery of yellow and purple cheatlines. The upper yellow lines represent mango, the unofficial national fruit. The thicker purple lines are based from the ube, and it sports a geometric ethnic design.[7]

The trains have round front ends, which bears resemblance to the 2nd-generation trains of Seoul Metro Line 1, Line 4, and Bundang Line; these EMUs are also manufactured by Rotem (or then KOROS).[8]

Trains prominently use wrap advertising.

  • Interior of a 2000 class train.

Interior

The inner train space is lined with melamine and/or polyester faced ply metal. The windows are tinted safety glass, and the longitudinal seats are made of fiberglass reinforced plastics.[9] The flooring is of stainless steel keystone plate and a thick, nonslip covering. Open-type gangways are present in between cars. These are 1,500 millimetres (4 ft 11 in) wide. In 2017, some trains are retrofitted with the Passenger Assist Railway Display System (now known as TUBE), a passenger information system powered by LCD screens installed near the inner ceiling of the trains that shows news, advertisements, current train location, arrivals and station layouts.[10]

Traction equipment

The bogie is a bolsterless type, the axle length is 2,200 millimetres (7 ft 3 in), the bogie center length is 1,580 millimetres (5 ft 2 in) The primary suspension consists of a conical rubber suspension and the secondary suspension is a diaphragm air spring.

Traction converter is IGBT-VVVF type, and one inverter is installed in each. The traction motor is a 120 kW three-phase AC induction motor.[11]

Operations

The trains currently run in 8 sets, with 8 trains being repaired/overhauled and 2 being repaired from a collision between Araneta Center-Cubao and Anonas Stations.[12]

Incidents

On May 18, 2019, 2 trains collided with each other between Araneta Center-Cubao and Anonas stations. A dead train parked at the Pocket track started moving by its own and wound up on the eastbound track, where it crashed into another train with passengers. The trains were soon towed to the depot the following day.
