"Police Activity Halts Metra Trains at Ogilvie Transportation Center"

Metra service on the Union Pacific-West, Union Pacific-North, and Union Pacific-Northwest lines is resuming with extensive delays following "police activity" at the Ogilvie Transportation Center in Chicago. Trains were halted earlier due to reports of a witness observing a shell casing, leading to a lockdown. A search of the building was conducted, but no suspect or further evidence was found. No injuries were reported, and no one is in custody.
