(CNN) About 20 train cars were sent off the tracks Sunday morning in Cincinnati.

A CSX train derailed around 5:15 a.m., sending seven to eight cars off the tracks about 10 miles west of downtown along the Ohio River. This caused another 11 to 12 cars from a parked train to leave the tracks also, District Chief Greg Potter told CNN affiliate WLWT-TV

No injuries were reported.
