CTA trains were stopped on the Blue Line between the Damen and Racine stops after a man died on the tracks at the Lake Street station.
The man was later identified as Elmer Williams of the 1600 block of West LeMoyne Street.
Williams, 55, was pronounced dead on the scene at 9:50 a.m. after apparently being electrocuted on the third rail. An autopsy is scheduled for Saturday.
The body was discovered on grates near the tracks
