“And then all of a sudden, there was a loud crash and the train just came to an abrupt stop, and we find out we hit a tree, or a tree fell and hit it,” said passenger Evangeline Griffin.

Authorities said 11 people were on the trains, including two Chicago Transit Authority conductors. Everyone was able to walk to safety.

Following the incident, the Chicago Transit Authority said shuttle buses were replacing service on the line from Howard to Dempster-Skokie, and the No. 97 Skokie bus can also be used as an alternative.
