ALBIA, IOWA (AP) -- Authorities say the railroad tracks may have been a factor in the derailment of 20 cars on a Burlington Northern Santa Fe freight train in Albia.
The derailment happened about 4:30 a.m. Thursday, causing three city streets to be closed.
No injuries were reported and no hazardous materials were involved.
Railroad crews separated the section of cars that had not derailed and moved them out of the intersections.
Most of the cars were empty.
Albia Police Chief Jay Andrews said the derailment could have been caused by the railroad tracks slightly separating.
