Purchase
In line with the construction of Line 2, 72 cars (18 sets) were produced by Hyundai Rotem between 2002 and 2003.[7] The trains were built in Uiwang, South Korea. The carbody was made by Hyundai Rotem, and the electric components were made by Toshiba. The trains were provided by the Asia-Europe MRT Consortium (AEMC), a consortium of Marubeni Corporation, Balfour Beatty, Toshiba, Daewoo Heavy Industries, and D.M. Consuji Incorporated (DMCI). The AEMC signed the Package 4 contract in 2000, in which includes the communications and fares systems, vehicles, and trackworks. 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.[3]
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.[3]
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]
Each car has two roof-mounted air-conditioning units manufactured by Carrier.[10] In total, there are eight air-conditioning units in a single train set.[11]
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.[12] 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.[13]
Traction equipment
The bogie is a bolsterless type, the axle length is 2,200 millimetres (7 ft 3 in), and 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.[14]
The original VVVF controller and propulsion system is supplied by Toshiba,[5] while the new VVVF controller and propulsion system done during the refurbishment period of three train sets is supplied by Woojin Industrial Systems.[1]

Operations
The trains have been in use since the opening of the LRT Line 2 in 2003. However, by 2014, 12 out of the 18 sets remained in service.[15] By May 2019, the number of operational trains were reduced to 8 sets following a collision incident involving two train sets,[16] and by October 2019, the number of operational trains in the line were reduced to 5 due to power supply limitations following a power trip incident.[17] By July 2021, operational trains were increased to six after the Line 2 East Extension opened, with five trains used in the original line and one train as a shuttle train along the east extension stations as the signalling integration works of the east extension stations to the railway's existing systems were not completed at that time.[18] By September 3 of the same year, these have increased to 8 sets after the completion of signalling integration works of the east extension stations to the railway's existing systems.[2] Currently, eight trains are operational, while the other trains are being repaired/overhauled or awaiting spare parts.
Train upgrades and refurbishments
On April 16, 2018, the Light Rail Transit Authority signed a contract with Multi-Scan Corporation and MRail, Inc. for the replacement of 80 air-conditioning units in 10 train sets.[11] The replacement of air-conditioning units started on March 7, 2019[19] and was completed on May 24.[20]
Rehabilitation of three train sets started on March 3, 2021. The current maintenance provider of LRT Line 2, a joint venture of Autre Porte Technique Global Inc., Multi-Scan Corporation, and Opus Land Inc., started the installation of new train propulsion systems and train monitoring systems from manufacturer Woojin Industrial Systems in three 2000 class trains in order for those trains to return to service ahead of the original scheduled opening of the east extension in April 2021.[1]
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.[21][22] Revenue operations were suspended to give way to maintenance checks, and normal operations resumed at 10:47 AM the next day.[23] Trainset no. 18 returned to service in June 2021,[24] while Trainset no. 13 returned to service in September 2021.
