There is currently no subway service on the TTC’s Line 1 between St. Clair West and Union stations, the transit agency says.
The problem was caused by the derailment of a work car on the southbound track at St. George Station, said TTC spokesperson Kadeem Griffiths.
As of 7:45 a.m., he was unable to say when regular service may resume.
TTC crews are still trying to assess the severity of the problem, Griffiths said.
“The priority right now is getting the car back on the rails as quickly as possible.”
Some 100 shuttle buses are running along that stretch of Line 1.
Commuter Elliott Turvis was on his way downtown for work. When he saw the crowds waiting for buses, he said, he thought “not this again.”
“It’s just a sinking feeling in my stomach,” he told CBC Toronto.
To get downtown, riders can transfer to the GO Transit network at Downsview Park, Kipling, Dundas West and Union stations , as well the UP Express, without paying an additional fare.
This is the second time in less than a month that a derailment has caused a significant TTC subway disruption.
