The LRTA 2000 class, also known by the Light Rail Transit Authority as the Rotem/Toshiba Megatren Model 2003, [10] 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 LRT Line 2. [5]

Contents

Purchase

In 1998, several Japanese companies were involved in the bidding for the rolling stock for the LRT Line 2, which, according to Senator Juan Ponce Enrile, were hounded with alleged anomalies. [14] Although it was promptly corrected by the Estrada administration after it assumed power in the middle of that year, it also encountered similar anomalies in May 2000, such as the disqualification of two bidders in the final evaluation for the project. Only two bidders, Ansaldo, and Mitsui with Siemens, passed the technical evaluation process. [15]

In September 2000, the Asia-Europe MRT Consortium (AEMC), a consortium led by Marubeni Corporation and consisting of Balfour Beatty, Toshiba, Daewoo Heavy Industries, and D.M. Consuji Incorporated (DMCI), secured the fourth package contract. It includes the communications and fares systems, train vehicles, and trackworks. AEMC won over the other bid, MMH Consortium, composed of Mitsubishi Heavy Industries, Mitsubishi Corporation, and Hyundai Precision (later merged with Daewoo Heavy Industries to form Rotem at the time of the bidding and also involved in the LRTA 1100 class rolling stock). [16] The first batch of trains consisting of four sets (16 cars) arrived in November 2002, while the remaining 14 sets were delivered in the succeeding months. [4]

Seventy-two train cars (18 sets) were produced by Hyundai Rotem between 2002 and 2003. [1] These were built in Uiwang, Gyeonggi-do, South Korea. [4] Hyundai Rotem constructed the main car body, while Toshiba provided the electric components.

Design

Car body

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. [4]

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). [17]

Each car has two roof-mounted air-conditioning units manufactured by Carrier that has a cooling capacity of 40,400 kilocalories (169,000 kilojoules) per hour. [3] In total, there are eight air-conditioning units in a single train set. [18]

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. [19] The seats have a length of 1.6 to 2.4 meters (5 feet 3 inches to 7 feet 10 inches). [20] The flooring is of stainless steel keystone plate and a thick, nonslip covering. Open gangways are present in between cars with a width of 1.5 meters (4 feet 11 inches). In 2017, some trains were 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. [21] However, as of 2022, the LCD screens remain switched off and unutilized.

Mechanical

Each car has two bolsterless bogies underneath the car with an axle length of 2.2 m (7 ft 3 in). [11] The distance between bogie centers is 15.8 meters (51 feet 10 inches). The primary suspension consists of an elastomeric spring and the secondary suspension is a diaphragm air spring. [22]

Mechanical Shibata couplers are present at the ends of the driver cabs, along with anti-climbers above it. Semi-permanent couplers are present in between cars (non-cab ends). [19]

Traction and auxiliaries

The traction system consists of VVVF inverters controlled by IGBT semiconductors. Two alternating current induction motors with a power output of 120 kilowatts (160 horsepower) are mounted on each bogie. [23] The original VVVF controller and propulsion system is supplied by Toshiba, [6] while the new VVVF controller and propulsion system done during the refurbishment period of three train sets is supplied by Woojin Industrial Systems. [24]

The auxiliaries consist of 3,300-volt static inverters and 110-volt DC batteries. [25]

Formation

The configuration of a four-car trainset is McMMMc.

Operations

The trains have been in use since the opening of the LRT Line 2 in 2003. However, by 2014, twelve out of the eighteen sets remained in service. [26] By May 2019, it was reduced to eight following a collision involving two train sets, [27] and by October, further reduced to five following a power supply incident. [28] By July 2021, running trains were increased to six after the opening of the east extension, [29] subsequently increased to eight by September. [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 ten train sets. It used parts from the original equipment manufacturer of the air-conditioning units, Carrier Corporation. [18] The replacement of air-conditioning units started on March 7, 2019, [30] and was completed the following May 24. [31]

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 trains in order for those to return to service ahead of the original scheduled opening of the east extension the following April. [24] Trainsets 09, 14, and 17 were the train sets refurbished. [32] The refurbishment was completed in the same year. [33]

Certain train sets feature upgraded signages, now in LED, instead of sign scrolls.

The Manila Light Rail Transit System, commonly known as the LRT, is an urban rail transit system that primarily serves Metro Manila, Philippines. Although categorized as a light rail system because it originally used light rail vehicles, it presently has characteristics of a rapid transit system, such as high passenger throughput, exclusive right-of-way, and later use of full metro rolling stock. The LRT is jointly-operated by the Light Rail Transit Authority (LRTA), a government corporation attached to the Department of Transportation (DOTr), and the Light Rail Manila Corporation (LRMC). Along with the Manila Metro Rail Transit System and the Metro Commuter Line of the Philippine National Railways, the system makes up Metro Manila's rail infrastructure.

There are many types of trains in Seoul but they are generally similar to each other. All Seoul Metropolitan Subway rolling stock follow the Japanese-style commuter/subway train interior layout of all-longitudinal seating with luggage racks above seats. Typically, train cars have four pairs of doors on each side. In between the doors are rows of either cushioned or non-cushioned seats for 7 people, except for the outer ends of each wagon where there are smaller rows of seats for 3 people, marked for the use by the elderly, disabled passengers, and pregnant women.

The Light Rail Transit Line 1, commonly referred to as LRT Line 1 or LRT-1, is a light rapid transit system line in Metro Manila, Philippines, operated by Light Rail Manila Corporation (LRMC) and owned by the Light Rail Transit Authority (LRTA) as part of the Manila Light Rail Transit System. Originally referred to as Metrorail and the Yellow Line, LRT Line 1 was reclassified to be the Green Line in 2012. It travels in a general north–south direction from Baclaran to Monumento, and then east–west from Monumento to Fernando Poe Jr. Currently, the line consists of 20 stations and runs on 19.65 kilometers of fully elevated route. Although it has the characteristics of light rail, such as with the type of rolling stock used, it is more akin to a rapid transit system owing to its total grade separation and high passenger throughput.
