On Oct. 8, the National Transportation Safety Board (NTSB) reported a broken rail caused the deadly train derailment. Video footage from a previous train's rear shows a broken rail. Report: Broken rail caused deadly I-25 train derailment The report said the rail, made out of two thermite field welds, showed signs of friction batter and sudden catastrophic failure. The north weld, which showed catastrophic failure, was created by BNSF in 2007, while the south weld (Weld #71) was manufactured on May 24, 2023. Thermite Field Weld #71 on May 29, 2023. Courtesy: NTSB Both rails joined at the weld showed they hadn't been previously drilled for joint bars and had a height difference. So far, track damages have been estimated to be $10,400,000 while mechanical damages are estimated at $2,353,722.
