On August 25, 2021, about 5:08 p.m. local time, Canadian Pacific Railway (CP) train 296-23, traveling on the St. Paul Subdivision toward St. Paul, Minnesota, collided with standing Union Pacific Railroad (UP) freight train M-SSDM-25 on main track 2, derailing two locomotives on the CP train and one locomotive on the UP train. The derailed CP lead locomotive then struck and derailed a railcar from BNSF Railway (BNSF) freight train HNTWBRC-25, which was stopped on the adjacent track, main track 1. There were no reported fatalities or injuries. At the time of the accident, it was daylight, the weather was 82°F with no precipitation, and conditions were clear. Damages were estimated to be a combined $674,300 by the three railroads involved.
We determined that the probable cause of the August 25, 2021, train collision was improper handling of the train’s air brakes by the engineer of Canadian Pacific Railway train 296-23, which resulted in his failure to bring the train to a stop at the red (stop) signal at control point Division Street.
