Toronto Metro Oil Leak 7 Times in 4 and a Half Months! Management asks for a thorough investigation!

Toronto's Public Transport Authority (TTC) said the hydraulic leak that shut down part of the Line 2 subway on Monday has occurred seven times this year across the transportation network. On the 16th, Leary, chief executive officer of the bus bureau, called for a scientific verification of the incident to understand the cause of the hydraulic leakage of these work vehicles.

"If it happens only once or twice, you say it's accidental, but when it happens three or four times, it's different," Leary said.

In the past five years, the bus bureau has experienced 10 hydraulic leaks, but this year there have been seven such accidents in five months, three this week alone, in stark contrast.

"What bothers me is the frequency of these leaks and the way they happen. For example, how does a hose that is reinforced with a steel wire braided leak -- I think it's very puzzling."

Leary also faces some difficult questions, including why this information has not been disclosed until now, and why communication within the bus bureau was not smooth when the subway was suspended.

He said an expert would be hired to "dissect, really dig in, what causes these problems".

Leary said it was too early to link the incidents, which is why he had brought in experts to address them. When asked if the leaks were intentional, he said he did not rule anything out.

In Monday's incident, a work truck leaked oil on the tracks between Bloor-Yonge and Castle Frank stations, causing a "track slippage condition" that required manual cleaning of the tracks, resulting in a shift between the two major tracks. Line 2 between George Station and Broadview Station was closed for nearly 12 hours.

The bus board also revealed at the meeting today that the leak on Monday occurred at Spadina Station, where workers drove the repair vehicle to Lower Bay Station, thinking it had been repaired, but when it was later towed back to Greenwood Station, 200 litres of hydraulic fluid leaked in the process.

A Toronto report found that $26 billion is needed over the next 10 years to maintain bus infrastructure.
