The MRTC 3000 class or ČKD Tatra RT8D5M LRV, also known as Tatra Train, is a class of high-floor light rail vehicles built by Czech tram manufacturer ČKD Tatra. It is currently used at Manila Metro Rail Transit System Line 3 and were the last made by ČKD Tatra before it was taken over by Siemens.

ČKD Tatra RT8D5M LRVs are owned by Metro Rail Transit Corporation (MRTC), and operated by the Department of Transportation (DOTr) thru DOTr MRT-3.

Purchase[]

In line with the construction of the Manila Line 3 in the 1990s, ČKD Tatra was chosen by the Metro Rail Transit Corporation to supply the new trains after the consortium won the project.

Aside from a prototype, 73 light rail cars are produced by ČKD in two batches; 49 were produced in 1998 and the other 29 were completed the following year.[8] The first train was flown into Manila via plane while the remaining trains were transported by sea.[9] The fleet also happens to be the last produced by ČKD before it was taken over by Siemens.[10]

Design[]

Structure[]

The LRV design is a one-way eight-axle motorized car consisting of three articulations, which are connected to each other by the joint and the cover.[11] Each rail car is provided with five double leaf, electronically operated plug-sliding doors. The three center doors have an open width of 1,255 mm, while the two end doors measures at 861 mm.

Unlike the prototype 0029, these cars have rounded "foreheads" or beveled large windows at both ends.[12]

The trains wear a livery consisting of royal blue, red, and white. Under the "Metrostar Express" branding, the white portion contains the brand logo and lettering on the sides. However, since 2012, the branding has since been unused.[citation needed] The trains also usually wore wrap ads—unlike the LRTA 1200 class which wear ads as a whole trainset, the 3000 class are seen to wear wrap ads per car.

Interior[]

Each train can seat 80 passengers and under crush loading conditions, each car can carry 394 commuters at any one time. Seats are longitudinal-type.

The Passenger Assist Railway Display System (PARDS), a passenger information system powered by LCD screens installed near the ceiling of the train that shows news, advertisements, current train location, arrivals and station layouts, are already installed inside the trains. PARDS is also installed on trains on LRT lines 1 and 2.[13]

Prototype RT8D5 0029[]

In March 1996 the first three-car tram was tested in Prague under the number 0029 as a prototype.[4] It was a development of the Tatra KT8D5; 0029 retained its control, proportions, the front and rear sections, and unlike the later production vehicles, designed for bidirectional operation. Prototype 0029 remained in Prague and it was used in October to November 1998 together with the Tatra-T5A5 prototype, tram no. 0013, and the T3 no. 6663 for various crash tests in the main workshop in Hostivař before being eventually scrapped.[12][14]

Operations[]

The trains run at a maximum speed of 65 kilometers per hour (40 mph), and run through standard rail tracks.[5] The RT8D5M operates as built on the high-speed city rail system with high platforms and in tropical conditions.[3][10] The vehicles are mainly operated in threes, and operations with four-car trainsets had been planned.[15] The trains have been in use since the opening of the line in 1999 and has undergone three refurbishments.

Refurbishments[]

A 3000 class train in 3-car formation in July 2021. LRV 3006 (front) was refurbished by Sumitomo in 2020.

In 2008, during the line's first general overhaul, the trains were first refurbished by Sumitomo Corporation, Mitsubishi Heavy Industries and TES Philippines Inc. (TESP). The aging air-conditioning units of the trains since 1999 were replaced with new ones.[16] The interior and exterior of the trains were also refurbished. Sumitomo Corporation, along with MHI and TESP refurbished 73 light rail vehicles (LRVs) from 2008 to 2009.

In January 2016, Busan Universal Rail, Inc., a Korean-Filipino consortium, was appointed as the maintenance provider of Line 3. Three LRVs underwent the second refurbishment in 2017. New air-conditioning units from Thermo King were installed in these three LRVs. BURI planned to overhaul 43 LRVs, but due to anomalies with the company and service interruptions at the time, BURI only refurbished three of them.[17]

The trains are currently undergoing the third and current refurbishment that begun on May 1, 2019, with the overall rehabilitation of the entire MRTC 3000 class fleet of 72 cars being carried out by the Sumitomo Corporation, Mitsubishi Heavy Industries and TES Philippines Inc. (TESP). The rehabilitation project of the LRVs consists of the installation of new choppers, wheels, pantographs, air conditioning units from Thermo King; the repainting of the train's exteriors and interiors; and the fitting of new lighting installations throughout the trains, with the overall refurbishment program of the trains are expected to be completed in December 2021.[18] Currently, 27 light rail vehicles (LRVs) are overhauled as of August 24, 2021,[1] while 5 LRVs are undergoing general overhaul.[19] SKD Trade, a. s., the company that produces spare parts for trains made by ČKD Tatra, is currently working with the Department of Transportation for the spare parts for the 3000 class trains as part of Line 3's rehabilitation project.[20]

Incidents[]

  • On November 3, 2012, a train from the Araneta Center-Cubao Station caught fire as it approached GMA-Kamuning Station, causing passengers to scramble to the exits, and having two women injured. The train caught fire due to electrical short-circuit technical failure.[21]
  • On August 13, 2014, a southbound train heading to Taft Avenue station derailed and overshot to the streets. The train first stopped after leaving Magallanes station due to a technical problem. Later on, the train broke down altogether, another train was used to push the stalled train. During this process, however, the first train got detached from the rails and overshot towards Taft Avenue, breaking the concrete barriers and falling to the street below. At least 38 people were injured. The accident was blamed on 2 train drivers and 2 control personnel for failing to follow the proper coordination procedures and protocol.[22][23] The train car involved has not been seen since, and is either under restoration or already scrapped, but no confirmation for its ultimate fate has been given.
  • On November 16, 2017, at 11:30 am, at least 140 passengers were evacuated from a "detached train" coach between the railway lines of Buendia and Ayala Avenue Stations.[24]
  • On August 7, 2018, an aircon leak caused '"rain" inside a train and caused passengers inside to open their umbrellas. The train was removed from service to fix the air conditioning unit and the train involved in the incident returned to service the following day.[25]
  • On May 7, 2021, a car of the 3000 class LRV (car 015) was vandalized by an unidentified culprit near Taft Avenue station. The authorities discovered the vandalized train on May 12, 2021. Investigations were conducted and initial reports say that the culprit had cut the perimeter fence near Taft Avenue station, which may have caused the vandalism.[26] The vandalized train was cleaned and returned to service on May 18, 2021.[27]
