A power supply problem was reported from Ayala to Taft stations some 15 minutes before the glitch and was resolved around 10:35 a.m., the MRT management said.

"We continue to investigate the cause of the power supply issue, and we sincerely apologize for the inconvenience," it said.

A styrofoam, meantime, was caught in one of the MRT-3's power lines along Ortigas southbound in Mandaluyong at around 9:48 a.m.

The train line's operation was unaffected. Authorities said they are looking for ways to remove the object.

The LRT-2 also stopped its operations from around 9:50 a.m. to 10:20 a.m. due to a "train fault" at Gilmore Station, said its management.

UPDATE: As of 2 Oct. 2019 at 9:49 AM, LRT-2 is temporarily stopping its operations for reasons yet to be identified. Apologies for the inconvenience. Please standby for further updates.
