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.​
