Colorado Railroads does not cover every grade crossing incident, but we can't ignore stuff like this.
According to the only surviving Denver newspaper, the Denver Post, a tanker truck in--where else?--Commerce City tried to beat the train and tied-lost. As a result, 5,200 gallons of ethanol were spilled, producing a fireball that was captured on private surveillance cameras. The truck, the switcher and pretty much everything at the crossing were burnt crisper than a tortilla chip and a total loss. The three men on the locomotive had injuries and a nameless driver for Roger Morris Trucking Co. escaped unharmed.
On further examination, the railroad involved was not indicated, but the switcher was a formerly cascade green Burlington Northern EMD SD road locomotive. The accident appeared to be a spur in the vicinity of the UP/BNSF crossover for the two lines northeast out of Denver, CP DS902 UP Junction.
