<p>SIBLEY, Iowa — An evacuation order remained in place Monday for part of a northwest Iowa town as firefighters worked to extinguish a burning train after a weekend derailment.</p>
<p>About 47 cars <a href="https://apnews.com/article/ia-state-wire-iowa-lifestyle-evacuations-c94407f054eec45fcc5d955500729ea2">derailed Sunday afternoon</a> near Sibley, including several cars that were carrying hazardous materials. The resulting fire created a thick plume of black smoke but no injuries were reported. </p>
<p>Sibley is a town of about 3,000 people roughly 200 miles (322 kilometers) northwest of Des Moines. The west end of the town was evacuated after the derailment.</p>
<p>Union Pacific spokeswoman Robynn Tysver said the railroad’s hazardous materials experts worked with first responders through the night to contain the blaze. </p>
<p>Tysver said several cars involved in the derailment were carrying hydrochloric acid, potassium hydroxide and asphalt. An empty tank car on the train had been carrying liquid ammonia nitrate.</p>
<p>The railroad said the cause of the derailment remains under investigation, but witnesses reported that a bridge had collapsed underneath the train.</p>
<p>Robin Eggink told the Des Moines Register that she and her husband noticed the train slowing down followed by a big cloud of smoke as they were eating at a Pizza Hut outside of Sibley on Sunday. The family drove near the site of the smoke and saw the train split in two on both sides of a bridge that had collapsed before firefighters ordered them out of the area, Eggink said.</p>
