(KAIR)--The railroad crossing at Atchison's 4th Street reopened Tuesday night at 10:00 more than 24 hours after Monday evening- Union Pacific train derailment that forced the closure.

According to Atchison Police Chief Mike Wilson, cleanup continues, but the crossing is cleared and no longer a factor.

Also continuing is the joint investigation between Atchison Police and Union Pacific officials into what caused the derailment of six empty coal cars around 6:35 Monday evening, which also led to response from the Atchison Fire Department, although the derailment caused no fire, property damages, or injuries.
