CTA trains hit deer a couple of times a year, usually long the wooded Yellow Line tracks at grade level.
But certainly deer strikes don't happen very often along Blue Line tracks in the middle of the Kennedy Expressway.
But that's what happened at about 3:15 a.m Wednesday, when a northbound Blue Line train struck and killed a deer just north of the Cumberland station.
The train was delayed for about 15 minutes as the carcass was removed from the tracks. There were no human injuries.
