A loose power component on the Confederation Line caused delays during the Wednesday afternoon commute, forcing LRT passengers to wait outside in bad winter weather for replacement buses.
At around 4:40 p.m., OC Transpo said part of the overhead power system east of St. Laurent station had come loose, forcing trains to be halted between St. Laurent and Blair stations.
One train was evacuated and passengers were told to board replacement buses, transportation services general manager John Manconi said.
