"According to Sumitomo-MHI-TESP, the cause of the incident was due to a short circuit in one of the traction motors (broken bearing cover)," DOTr said in a statement.
"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 added.
Some 530 passengers at the northbound Santolan station were unloaded after one of its trains emitted smoke on Monday, November 4.
Due to the incident, provisional service was implemented from Shaw Boulevard to Taft Avenue at around 4:30 p.m. Regular train operations resumed at 6:06 p.m. that same day.
The DOTr assured that several countermeasures were formulated such as crack testing on all bearing cover of traction assembly, systematic checking of protective device, cleaning of all electrical boxes, and insulation test on high voltage cables.
"We appeal to the riding public’s understanding while the massive rehabilitation of MRT-3 system is ongoing," the DOTr said.
"Rest assured that the MRT-3 Management and Sumitomo are doing everything to provide reliable and safe trains for passenger service," it added.
To recall, another MRT-3 train unloaded its passengers in March 18 after it emitted smoke while transiting between Cubao and Santolan stations.
Investigation revealed that a short circuit in the high voltage wire of the traction motor also caused the smoke, the MRT-3 management said.
In May, Sumitomo-MHI-TESP started handling all rehabilitation and maintenance works for MRT-3 to restore the railway system back to its original condition.
It is expected that the MRT-3 rehabilitation project will increase the number of operating trains during peak hours from 15 to 20, double operating speed from 30 to 60 kilometers per hour, and cut by half the time between trains from 7-10 minutes to 3.5 minutes.
