Circumstances around the incident weren’t immediately known — but a bus shuttle was operating between the Howard and Belmont stations, CTA said.

According to the Chicago Sun-Times, officers were called to the 7500 block of North Paulina Street around 11:25 a.m. Monday. There, they found an unidentified 58-year-old woman unresponsive aboard the train, and she was pronounced dead shortly afterward.
