This article https://www.cbc.ca/news/canada/ottawa/ottawa-lrt-train-wheel-rail-problem-report-1.7588002 made a lot more sense after reading this article @VE2UWY@mastodon.radio linked https://practical.engineering/blog/2023/10/3/why-are-rails-shaped-like-that If the rails are soft then the wheels are going to dig in and not ride up the wheel at all hence squealing as they dig in. Thank you Jim for a legacy to be proud of! #Ottawa
