Catholics in Chicago can receive ashes during their commute on Ash Wednesday as part of a service being offered by the Archdiocese of Chicago. In addition to parish locations in Cook and Lake counties, Catholics can also receive ashes at two Chicago CTA stops, Union Station and at both airports, according to the archdiocese. The ashes used on Ash Wednesday are made from the palm branches used on the previous Palm Sunday. Ashes are applied to the forehead of a commuter at an L train Stop during a celebration of Ash Wednesday in Chicago, Illinois.
