A man was fatally struck by a Brown Line train Monday morning in the Ravenswood neighborhood on the Northwest Side.

Spencer Woodland, 18, was walking on the tracks about 6:40 a.m. in the 4600 block of North Western when he was struck by a train and subsequently fell from the tracks, according to Chicago Police and the Cook County medical examiner’s office.

The man was taken to Illinois Masonic Medical Center, where he was pronounced dead less than an hour later, authorities said. An autopsy Tuesday did not rule on the cause and manner of his death pending further investigation.

Trains were halted after the incident, but service had resumed by 8:41 a.m., according to alerts from the CTA.
