Wheel axle issue to blame for Ottawa LRT issues
Alstom says they have found a fix for issues with the axles on Ottawa’s light rail transit system, but the train operator isn’t convinced about the root cause.
I hope everyone had a nice weekend. For the first time in a VERY long time, it was actually a slow weekend in news.
Alstom says they have found a fix for Ottawa’s problem-plagued LRT system, but those solutions are far off. While sceptical, transit riders are hoping this will bring an end to shutdowns.

Moving toward an LRT fix
What happened: Train-maker Alstom said they have found the root cause of why Ottawa’s light rail transit system had issues with its bearings in 2021. Higher than expected lateral loads on the vehicle's axles during operation is to blame, according to CTV.
The other problem: Rideau Transit Group (RTG), the private consortium that runs the LRT, and Alstom are not on the same page about what causes the failure. Alstom said the higher-than-expected lateral forces from the rail on the wheel loosen a nut inside the hub assembly, causing the part to fail. But RTG isn’t convinced, CBC reported.
The consortium’s CEO said they may come around to the idea that the excess forces are to blame, but they aren’t in agreement yet.
“One of the key things that everyone agrees about is the nut coming unscrewed as being a key portion of that and how that needs to be a focal point no matter what is the sequence of events that brings the nut to being unscrewed," Alstom vice-president David Van der Wee said.
Track fixes? Also up for consideration is using a harder rail material on the LRT’s tighter curves, and other upgrades that would keep the sections where the rail is under the most stress from distorting, according to CBC.
The city’s view: OC Transpo ultimately doesn’t care whether the two sides can agree on what is making the trains break, only that the final fix actually works. Transit chief Renée Amilcar said the disagreement between the two sides was a commercial one, and the city isn’t going to take a side. Ultimately, they want to see the redesigned, and reinforced wheel hubs put in place.
“I have advised them that the City of Ottawa is interested only in the permanent technical solution to this issue, and not commercial debates that may arise with them,” Amilcar said, according to CBC.
Solutions: Rideau Transit Group will now start inspecting each axle assembly after every 3,750 kilometres of use, or about once every 10 days, reports the Ottawa Citizen.
The fix? a pin will be used to hold the nut in place or a second locking nut to keep it from moving. That should reduce the number of costly and time-consuming inspections needed, says Alstom. That will take time and a prototype isn’t expected to be ready until 2025, when it will then undergo testing before preoval for has.
“You deserve better. I want to encourage you that you have the full commitment of Alstom to be able to work very tightly with our partners to be able to bring the system back to what was promised and what is deserved,” Van der Wee said, according to CityNews.
