Authorities said the incident took place inside a train car, with a witness telling investigators that it began as an argument near Kedzie Avenue, then moved onto the platform "after an unknown person had pressed the assistance button near the Austin Boulevard."
A 34-year-old woman was taken to Loyola University Medical Center for treatment, according to police, who said the extent of her injuries were unknown.
Officials said a 26-year-old man was taken into custody at the scene.
