Here's what you need to know about the LRT bearing problem



OTTAWA —Ottawa's light rail transit system is no stranger to disruptions, and the recent full closure due to a bearing issue has once again left commuters frustrated and concerned about the system's reliability. The three-year-old LRT system has encountered multiple setbacks in the past, including a derailment and closures caused by ice storms. The current bearing problem has raised questions about the system's design, maintenance, and overall safety.


The recent shutdown was triggered by a bearing issue that impacted the Citadis Spirit vehicles, causing a significant operational challenge. As the LRT system underwent inspections and maintenance to address the problem, authorities found connections to previous derailments, which were linked to axle problems resulting from loose cartridge assemblies. The recurrence of these issues and ongoing failures have raised concerns, prompting the Transportation Safety Board to express apprehension regarding the city's response to safety recommendations.


The LRT system's axle hubs and cartridge assemblies have been identified as primary points of concern, leading to frequent shutdowns and disruptions in service. The Transportation Safety Board's investigation highlighted widespread damage and attributed the recurring problems to the design of the Citadis Spirit vehicles and their powerful drivetrain. The wheel/rail interface has become a critical focus of the investigation, raising the possibility of a major overhaul to ensure safer and more reliable service in the future.


As the transit authorities work diligently to resolve the bearing problem, they face mounting pressure to find a comprehensive and permanent solution. Commuters and residents are increasingly voicing their concerns over the system's overall safety and reliability. The LRT system was implemented with the promise of improving public transportation and reducing traffic congestion in the city, but the recurring issues have left many questioning its effectiveness and viability.


The city's response to the ongoing bearing problem and the Transportation Safety Board's findings will undoubtedly have significant implications for the future of Ottawa's LRT system. Commuters and residents alike eagerly await a clear plan of action and assurance that their safety is of the utmost priority.
