Rail transportation safety investigation R25W0047
On 28 June 2025, a Canadian National Railway Company (CN) freight train was travelling east on the Fort Frances Subdivision when it experienced a train-initiated emergency air brake application near Devlin, Ontario.
As a result, the last 13 loaded grain hopper cars at the tail end derailed. Most of the derailed cars were extensively damaged and released their product. No dangerous goods were involved, and no injuries were reported. The TSB is investigating.
