<p>SIBLEY, Iowa — An <a href="https://apnews.com/article/iowa-evacuations-d47aa1754a78a22cbccb552ea9348228">evacuation order</a> that was issued for part of a northwest Iowa town following a fiery weekend train derailment has been lifted, authorities said.</p>
<p>The Osceola County sheriff’s office announced Monday night that people were allowed to return to their homes and affected businesses would be able to reopen.</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 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>Several cars involved were carrying hydrochloric acid, potassium hydroxide and asphalt, Union Pacific spokeswoman Robynn Tysver said. An empty tank car on the train had been carrying liquid ammonia nitrate.</p>
<p>The railroad said the cause of the derailment was under investigation, but witnesses reported that a bridge had been damaged underneath the train.</p>
<p>Tysver said the bridge may have been damaged during the derailment but it did not collapse.</p>
