Southwest Chief hit the rear end of a 2007
Kenworth W900B dump truck that was partially fouling the railroad crossing on County Road 113 (also known as Porche Prairie Avenue), a
gravel road located approximately southwest of the small town of
Mendon, Missouri. Preliminary reports from the
Missouri State Highway Patrol (MSHP) stated the train hit the dump truck at a
passive grade crossing that was characterized as "uncontrolled", having only
crossbuck signs and a stop sign to the right of the road for vehicles traveling north; The rails run on an elevated berm approximately above the road surface and consequently the highway grade "approach ... is very, very steep"; in addition, the county had warned both the state of Missouri and BNSF in May 2022 that overgrown brush next to the crossing had compromised the visibility of rail traffic. A train passenger told reporters that suddenly the car he was traveling in flipped over and the passengers, seats, bags, and other debris were tossed everywhere. After it stopped, he said, he could smell fumes everywhere, causing many to panic about the possibility of fire. Another passenger, traveling in a sleeper car, said the car rocked for a bit and the lights flickered before there was dust coming through his window. He grabbed his backpack before evacuating the train with other passengers, and then he and others helped other passengers reach the ground after evacuating the cars. A group of
Boy Scouts from Wisconsin was on board the train, returning from a trip to the
Philmont Scout Ranch; they provided first aid to victims until emergency crews could reach the remote area. Locals who lived near to the tracks helped move first responders, the injured, and debris with their all-terrain vehicles. == Victims ==
