Train service on the CTA’s Blue Line was suspended Sunday on the Northwest Side after a man was hit and killed by a train.

About 3:05 a.m., Joshua Bruen, 34, was struck in the 2900 block of West Fullerton Avenue, Chicago police and the Cook County medical examiner’s office said.

He was pronounced on the scene, authorities said. He lived a few blocks away from where he died.

Service was suspended about 3:30 a.m. between the Montrose and Grand stations but trains were running again with residual delays about three hours later.

Chicago police are conducting a death investigation.
