 Prior to the 1990s, the station was known as River Road, as the CTA did not feel that the names of stations should advertise cities outside Chicago limits.The station name was changed in the mid-1990s, around the same time that the and Desplaines terminals on the Yellow and Blue Lines were renamed to reflect the suburb they serviced rather than the cross street.The platform is wedge-shaped, with the width increasing from east to west, due to the Rosemont Yard sitting immediately west of the station, between the inbound and outbound tracks.
