Hydraulic Oil Spills on the Subway

Subway service on the central portion of Line 2 Bloor-Danforth was suspended for over 12 hours on Monday, May 13 due to a spill of hydraulic fluid on the tracks. The replacement bus service was swamped by the combination of subway demand and congestion on Danforth Avenue and Bloor Street. The situation was compounded by changing and incomplete information about the extent and potential duration of the problem.

This was initially described as a spill somewhere between Sherbourne and Castle Frank Stations with the impression that the directly affected area was small. In fact, the volume was large, 200L of hydraulic fluid, and the area ran from Spadina to Greenwood Yard (east of Donlands Station). Trains could not operate safely until the rails were cleaned and operators could brake with confidence that trains would actually stop correctly.

This was not the first such incident. At a TTC Board Meeting earlier in 2024, ATU Local 113 had raised the issue of operational safety after a similar, albeit smaller problem in January at Eglinton West Station. Following the May 13 spill, the ATU wrote to the TTC Board raising basic questions about the incident, and by implication how well-informed the Board actually was about ongoing issues with subway safety.

At the May 16 Board meeting, management gave an extensive presentation about hydraulic fluid leaks and the recent increase in the frequency of these events. It is not clear whether such a detailed presentation would have occurred without the ATU going directly to Board members. Management’s credibility and transparency have been open to question following a near-miss incident at Osgoode Station that went unreported to the Board for almost a year, as well as track and infrastructure problems including the SRT derailment, and the need for ongoing slow orders due to problems with subway track.

CEO Rick Leary has retained external consultants, Hatch LTK, to review these incidents, and there will be a peer review by APTA (American Public Transit Association).

A much broader concern is subway delays of various types and how they are handled. Some have external causes (passengers wandering at track level, for example), but some are “own goals” in the sense that they arise from operational or infrastructure issues that could have been prevented. Whatever the reason, all of them strain the subway’s ability to provide reliable service. This works directly against the drive to restore transit’s credibility and attract new and returning riders.

Far more is needed than free Wi-Fi here and a new kiosk there. Creature comforts are nice, but the service must be trustworthy. The TTC’s fundamental job is to move people. The lion’s share of delays might be due to external factors beyond the TTC’s control, but how they react to delays is key.
