The LRTA 2000 class is a class of electric multiple units of the Light Rail Transit Authority (LRTA) in Metro Manila, Philippines, which began operation in 2003. It is used in Line 2.^[4]

Purchase[]

In line with the construction of Line 2, 72 cars (18 sets) were produced by Hyundai Rotem between 2002 and 2003.^[8] The trains were built in Uiwang, South Korea. The carbody was made by Hyundai Rotem, and the electric products were made by Toshiba. A total of 72 cars were produced to service in Line 2. The first batch of trains consisting of 4 sets (16 cars) arrived in November 2002, while the remaining 14 sets were delivered in the next months.^[1]

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.^[1]

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).^[9]

Trains prominently use wrap advertising.

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.^[10] 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.^[11]

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.^[12]

Operations[]

The trains currently run in 8 sets, with 8 trains being repaired/overhauled and 1 being repaired from a collision between Araneta Center-Cubao and Anonas Stations.^[13] Prior to the opening of the Line 2 East Extension, the number of trains in the line was reduced from 7 to 5 due to power supply limitations brought by a power trip that occurred in October 2019. The number of running train sets increased to 8 sets since September 3, 2021 due to the completion of the integration of the east extension stations to the railway's existing systems.^[2]

Incidents[]

• On May 18, 2019, trainset no. 13 broke down between Anonas and Katipunan stations at 2:00 PM and was subsequently moved to the pocket track of Anonas waiting to be towed back to the depot. However at 9:15 PM, the train was reported to have moved on its own towards the eastbound track going towards Santolan station. At this time, trainset no. 18 was going towards Santolan station from Cubao station on the same track. The runaway train was reported via radio but eventually ran into train No. 13, injuring 34 passengers, with none in critical condition. The driver of one of the two trains was reported to have jumped out of his train before the collision, sustaining wounds and bruises.^[14][15] Revenue operations were suspended to give way to maintenance checks, and normal operations resumed at 10:47 AM the next day.^[16] Trainset no. 18, the train involved in the incident, was repaired and returned to service in June 2021, while Trainset no. 13 is still undergoing repairs as of the time being.^[17]
