MANILA, Philippines – The smoke emission incident at a Metro Rail Transit line 3 (MRT-3) train that prompted the unloading of some 530 passengers at northbound Santolan Station on Nov. 4 was due to a short circuit, its operator said Thursday.
In a statement, the MRT-3 management said a short circuit in one of the traction motors (broken bearing cover) caused the incident according to the investigation of its maintenance provider Sumitomo.
“It also showed on the affected parts that high current flowed in the circuit, causing significant damage to the electrical box and adjacent parts,” it said.
To prevent the recurrence of such incident, the MRT-3 management said it has placed countermeasures such as crack testing on bearing cover of traction assembly, checking of protecting device during emergency and regular maintenance, thorough cleaning of electrical boxes and insulation tests on high voltage cables.
“We appeal to the riding public’s understanding while the massive rehabilitation of MRT-3 system is ongoing,” it said.
National Capital Region Police Office (NCRPO) chief BGen. Debold Sinas confirmed on Tuesday (November 5) that his office is gradually removing the members of the Regional Mobile Force Battalion from guarding the MRT and LRT stations.
Providing security in MRT and LRT stations will now be under the jurisdiction of the local police districts.
The police district will be the one to assign police personnel in the stations covered by their office.
“Pinababa ko na yung around 400 doon sa istasyon, kasi ang idea ang may juridiction niyan lahat local. Pag may nahuli diyan local po magpa file ng case. Imaginin niyo yung mobile force namin na may long firearms at fatigue, ayaw niyo sigurong makita yun,” Sinas explained. (with details from Lea Ylagan) /mbmf
