TTC orders subway trains to slow down in reduced speed zones

If you've ridden the subway in Toronto in recent weeks, you may have noticed your commute taking longer than usual.

That's because the TTC has implemented dozens of "reduced speed zones" across major portions of Lines 1 and 2.

The zones are areaswhere trains must slow down because the tracks are in need of repair.

They were identified through a geometrysurveyconducted in May where a specialized device took laser-guided measurements of therail gauge the distance between the two rails on a track as well as the elevation and wear to the tracks, to identify issues notvisible during regular track inspections.

The surveyfound trackareas thatneed to be brought back into compliance with industry standards, saidFortunato Monaco, chief of operations and infrastructure with the TTC.

"When track is built, it's built to a particular standard. For the track to remain safe, it needs to be monitored, maintained and surveyed," Monaco said.

"You want the two rails tobe a certain distance apart. If they get too tight or if they get too far and they don't meet the standards, we need to slow the speeds down until we can take their proactive measures to get the gauge back in alignment."

CBC Toronto rode the subway between Bloor and Rosedale stations last week, using a speedometreapp. The northbound sectionis one of the spots that the TTC has identified as a reduced speed zone, while the southbound portion operated normally.

Monaco says the zones coverabout seven per cent of the subway network. The majority are on Line 1, he said, prolongingthe average trip betweenVaughan and Finch stations by an average of15 minutes.

"We appreciate the inconvenience of it, but it's ultimately meant for safety," he said.

The TTC says it expects much of the maintenance work within the zonesto be completed by the fall.
