PNR to validate Dalian MRT train repair findings

THE Department of Transportation (DoTr) has directed the Philippine National Railways (PNR) to supervise the testing of train sets manufactured by China’s CRRC Dalian Co. for the Metro Rail Transit Line 3 (MRT-3).

PNR General Manager Junn B. Magno said he was instructed by Transportation Secretary Arthur P. Tugade to validate the report of third-party auditor TUV Rheinland on the train sets before Sumitomo Corp. takes over as the railway’s maintenance provider.

“The report enumerated the reliability factors and the hazard factors of the train sets so we need to test that before we put it into revenue service,” he said during the Senate budget hearing of the DoTr on Tuesday.

He said the PNR was tapped since it has a division in the agency which deals with the reliability and maintainability of its trains.

Mr. Magno said the PNR will conduct simulations next week to check for possible major hazards with the train sets that the Chinese firm may have missed in its repairs.

After the simulation, the train sets will be placed in provisional revenue service by the MRT-3 for at least 150 hours. Mr. Magno said the testing may be conducted this month or October.

Mr. Magno said the PNR will then provide a recommendation to Mr. Tugade whether the train sets are suitable for revenue service or whether there is still a need for CRRC Dalian Co. to rectify some issues.

“If there are still hazards, we will not finish the 150 hours and will return the trains to (CCRC) Dalian so they will rectify it,” the PNR General Manager said.

DoTr Undersecretary for Rails Timothy John R. Batan said Toshiba Infrastructure Systems will also assist the government to validate whether CCRC Dalian has repaired the issues raised with the train sets identified by TUV Rheinland.

“We will run the trains first outside revenue hours so it would not affect operations when there are passengers and later on we will do it during revenue hours… Then, we will gradually deploy the trains in the existing fleet for longer period of time,” he told reporters after the legislative hearing.

He said the process of the simulation and testing will be discussed in a meeting with the various parties on Thursday.

The DoTr hopes to deploy the Dalian trains by the end of the year after it obtained the Chinese firm’s assurance it will shoulder the costs of any modifications.

Mr. Tugade stressed the importance of the deployment of the Dalian trains during the MRT-3 rehabilitation.

“We really need to use the Dalian trains. They said it can be used. If rehabilitation starts with MRT, only 10 trains may be operational. That would be a problem to the commuters. How can we meet the ideal target of the 600,000 passenger ridership with only 10 or 12 trains?” he said during the budget hearing.

The DoTr and the Japanese government, through the Japan International Cooperation Agency (JICA) finalized in May the terms of the rehabilitation for the MRT-3, which will take 43 months. — Camille A. Aguinaldo

Dalian MRT3 trains test run in October

The government wants to test whether the trains delivered by Chinese firm CRRC Dalian Company Limited are safe for public use

The unused Metro Rail Transit Line 3 (MRT3) trains delivered by Chinese firm CRRC Dalian Company Limited will be tested for public use sometime in October, railway officials confirmed.

During the budget briefing of the Department of Transportation (DOTr) on Tuesday, September 11, Philippine National Railways (PNR) General Manager Jun Magno said that the 48 unused trains will undergo testing to determine whether these are safe for public use.

Dalian said it was able to rectify "hazard" issues related to the trains, and this is what PNR will test, together with Toshiba Infrastructure Systems. (READ: Dalian trains may be used later this year but...)

"Ang gagawin lang namin, subukan natin 150 hours patakbuhin [kung] totoo ba 'yung hazards na narectify na 'yan. So kung may hazards pa rin, hindi na namin tatapusin yang 150 [hours], isa-sauli na namin," Magno told reporters on Tuesday.

(What we will do is we will test-run the trains for 15 hours to know if it's true that the hazards were already rectified. If there are still hazards, we will not finish the 150 hours and send them back to Dalian.)

Magno noted that the government wants to keep a very low hazard probability, close to the rates when the MRT3 was turned over by the original manufacturer Japanese firm Sumitomo-Mitsubishi Heavy Industries, Ltd.

He said that a hazard probability of 0.1% could still cause accidents and affect close to 100 passengers a year – a turnout that the government wants to avoid.

"Kaya nga may simulation muna kami para 'yang obvious na hazard matanggal na namin [ang tren sa test run]. Tapos 'yang mga hidden hazards na 'di pa namin nakikita, 'yun ang te-testing namin. Kunwari sa 150 [hours], may hidden hazard na malaki talaga, tatanggalin namin. Papa-rectify sa Dalian," Magno said.

(The reason why we have an initial simulation is so we can identify the trains with obvious hazards and remove them [from the test run]. The hidden hazards, we will be able to identify them during the test run. If there are huge hidden hazards during the 150-hour test run, we will remove them. Those have to be rectified by Dalian.)

The trains, when fielded for a test run, will be done during revenue operations. Magno estimated inserting two to 3 trains at a time, on top of the regular 15 trains servicing an average of 350,000 commuters daily.

Dalian will assume all costs related to repair of the unused trains, as well as providing spare parts, Transportation Secretary Arthur Tugade said.

Agreement

Railways Undersecretary Timothy John Batan said that the timeline of the test run is still being finalized.

Sumitomo, the original builder of MRT3, is set to come in as the new maintenance provider of the train system. Batan said the government is targetting the signing of agreements by the end of September to coincide with the test run of of Dalian trains.

"Practically speaking, transition [to Sumitomo] is already ongoing because there are talks already. But the full mobilization will take time between now and October," Batan said.

The 48 Dalian trains were delivered in 2016 but remained unused due to supposed compatibility issues. The DOTr said the Dalian trains exceeded the total weight required in its contract, specifying that each train should weigh 46.4 tons, but the delivered trains weighed 49.7 tons.

The new coaches were part of the MRT3 expansion project, which aimed to decongest the railway system and increase its capacity to serve over 800,000 passengers daily.
