(STMW) –CTA Green Line trains are on the move again Sunday morning after a minor derailment on the South Side.

A southbound train derailed near the Ashland/63rd station at 5:45 a.m., CTA spokesman Steve Mayberry said.

No passengers were on board the train and the operator was not hurt, Mayberry said.

Bus shuttles ran between the Ashland/63rd station and Garfield for about three hours until service was restored a few minutes before 9 a.m., according to the CTA.
