Trains in Chicago are not stopping at Harlem on the Forest Park Branch line after a collision earlier this morning.
Meanwhile, service has been restored to Forest Park.
“We apologize for the inconvenience and appreciate your understanding,” said the Chicago Transit Authority in a customer alert.
There is not estimated time for service to be restored.
Normal service continues on the rest of the transit authority.
48 people were injured in the collision, which may have been a hijacking.
