What Happened to Railroad Friction Bearings? The Oily Rags That Derailed Trains

A wad of oily cotton helped power American railroads for more than a century — and also helped cause some of their worst disasters. In this episode of Weirdward Bound, we trace the deadly history of the railroad “hot box,” from the 1833 crash that injured Cornelius Vanderbilt, to the 1943 Frankford Junction disaster, to the Mississauga evacuation, and finally to East Palestine. It’s a story about obsolete technology, corporate inertia, hidden risk, and the terrifying fact that the same basic failure keeps coming back in new forms. Expect derailments, engineering history, regulatory failure, and one unsettling question: how much do we really know about what’s happening underneath a moving train?
