Overview
- A Canadian Pacific Kansas City freight train went off the tracks near Priddis Slough, leaving 13 railcars damaged and several lying in the pond and surrounding wetland.
- The derailed cars were carrying lumber, plywood, propane and high‑pressure argon gas, materials that raise safety and environmental concerns even though no leaks have been reported.
- CPKC and Calgary emergency crews say there are no injuries and no indications of leaks from tanker cars at the scene.
- The Transportation Safety Board of Canada has deployed investigators to determine the cause and to guide environmental and cleanup assessments.
- Priddis Slough is a local pond and wetland used by waterfowl and other wildlife and sits between nearby residential communities, so officials will monitor wildlife, water quality and public safety as the response continues.
