Trains running on the north-south line 1 had to bypass the station for about 45 minutes, but have since resumed normal service, according to TTC spokesperson Brad Ross.
Ross tweeted that although the fire is out, crews still must attend to some repairs before service on line 2 can resume.
Sixty shuttle buses are operating between St. George and Pape stations, Ross said, as electricians work to replace a feeder cable to the third rail that sustained “major damage.”
West-end passengers needing to get downtown can travel by GO or UP Express with TTC fare, Ross said. West-end travellers can start their journey at the Kipling GO station, he said, while east-end travellers can use the Danforth or Kennedy GO stations.
Ross also warned of longer than typical wait times on the west end of line 2 because the stoppage has trains “trapped” in the Greenwood yard, which is east of Yonge. The incident began when TTC crews reported hearing a loud bang at track level about a half hour before the morning commute was set to begin, according to CBC’s Tony Smyth. Crews were forced to flee the station as smoke could be seen at street level.
Around 6 a.m., as subway service was set to get underway, the TTC announced that shuttle buses will transport passengers between St. George and Pape due to the fire investigation.
At the same time, the Toronto Fire Service tweeted that firefighters found a small fire on the third rail.
Meanwhile, paramedics were called to treat two TTC workers for smoke inhalation, Smyth reported. They were treated at the scene, he said, and would not be transported to hospital.
