More tests would have to be conducted on 48 Chinese-made Dalian train coaches, which were bought under the Aquino administration, before they could be used by Metro Rail Transit 3, the Department of Transportation (DOTr) said on Tuesday.
The DOTr made the announcement three days after the report by independent audit firm TUV Rheinland was supposed to have come out.
The release of the report is expected to pave the way for the rollout of the coaches, which have been gathering dust for over a year now at the MRT 3 depot.
The firm鈥檚 assessment has been 鈥渟ubstantially completed,鈥� according to the DOTr.
But according to TUV Rheinland鈥榮 interim report, which has been submitted to the DOTr, there鈥檚 still a need to gather 鈥渁dditional information on design and validation evidence.鈥�
There鈥榮 also a need to conduct more 鈥渢ype and routine tests鈥� on the coaches, made by the CRRC聽Dalian聽Co. Ltd.
One of the tests that the audit firm recommended deals with the weight of the coaches.
The DOTr said this test would be needed since 鈥渢he previous project team failed to attend and witness the weight testing done in Dalian, China, in November 2015.鈥�
鈥淸T]he weighing test should be done to eliminate any doubts, and so DOTr MRT 3 can witness and formally sign off on the trains鈥� weight,鈥� the DOTr said.
Earlier, rail officials pointed out that the P3.8-billion coaches were overweight by at least 3 tons.
In the contract, the DOTr specified coaches weighing 46.3 tons each. But those that were delivered weighed 49.7 tons each.
During a recent Senate committee hearing, former MRT consultant Rolf Bieri pointed out that the DOTr also specified that the trains should have an axle weight of up to 10 tons.
By his calculations, he noted that the Dalian trains would still be within the allowable limit even if it were to be fully loaded with passengers.
Still, the DOTr maintained that it had to be thorough to ensure that the Dalian trains would safe and compatible with the MRT 3 system before it could be used by the public.
鈥淜nowing that the Dalian trains will affect the safety of hundreds of thousands of MRT 3 passengers daily, the DOTr and MRT 3 management will ensure that the necessary processes are observed in their (TUV Rheinland鈥檚) assessment,鈥� the DOTr said. 鈥淩egardless of the independent assessment鈥檚 outcome, this administration remains committed in running after the officials that caused the current degraded state of MRT 3.鈥�
The DOTr did not say, however, when the weight test on the trains to be held in聽Manila would be done and when the full audit report could be expected to be submitted.
The rollout of the 48 Dalian train coaches, all fully delivered in January last year, could significantly improve the reliability of the country鈥檚 busiest train line, which is currently down to just 10 operational trains. /atm
