It was another day of scrambling for commuters who use the O-Train.

The service is currently out of commission.

The city re-launched an expanded O-train service yesterday, but had problems that caused delays of close to an hour.

Today there were more signal and switching issues on the track, so train service was halted entirely.

Passengers were re-routed onto buses.

A brief statement from the city said, “O-Train Trillium Line service is suspended until further notice. Supplemental Route 107 trips are running.”

Crews are working to repair the issue and OC Transpo says O-Train service will remain suspended until at least Thursday morning.
