After several reorganizations the Wabash Railroad was leased by the Norfolk and Western Railway on October 16, 1964. The single round trip continued under the new ownership, who named the train the Orland Park Cannonball. On May 1, 1971, Amtrak assumed control of most intercity passenger trains in the United States. On this date all intercity services operating into and out of Chicago were either routed into Union Station or discontinued, leaving the single Orland Park Cannonball as the only train to still use Dearborn Station. Dearborn Station closed, but the commuter train continued to use a small platform and track on the property until 1976 when it relocated to Union Station, via a new connection at Alton Junction.
