The Le Sueur County Sheriff said the early morning train derailment near Ottawa remains under investigation.
Sheriff Brett Mason said dispatch received the call that the locomotive and about 12 cars came off the tracks just before 5:00 a.m. Friday. The train was pulling just over 100 empty coal cars at the time of the incident.
As a result of the derailment, Mason said some diesel fuel spilled onto the ground, sparking a fire. The fire was brought under control and Mason said it was allowed to burn out. Because of the fuel leak in close proximity to a creek hazmat crews were brought in to help with cleanup.
It took fire crews a little over 20 minutes to locate the exact spot of the derailment, and the winter conditions created a challenge getting to the site.
Mason said there were no serious injuries but the rail crew was taken to the hospital as a precaution.
His office, the Le Sueur Fire Department, Union Pacific Railroad, and others continue to investigate the cause of the derailment. First responders on the scene initially said it appeared that the rail bridge over the creek may have failed.
