Hundreds of Metro Rail Transit commuters were inconvenienced anew when the rail line suspended its operations during yesterday morning’s rush hour.

The MRT said its signaling system detected a problem when the uninterruptible power supply device at the North Avenue station malfunctioned at around 9:25 a.m.

“It was not safe to travel and the advice was to stop operations while the problem is being addressed,” a member of MRT general manager Roman Buenafe’s staff said.

The MRT resumed operations at around 9:50 a.m.

The rail line suspended operations three times on Wednesday, saying there was “no traction,” but an insider said the MRT encountered a problem because officials failed to purchase carbon brushes, which convey electricity between the stationary and moving parts of an electric generator or motor. – Robertzon Ramirez
