Hiawatha from all terminals occurred on October 29, 1955. On the next day, October 30, 1955, the Milwaukee Road assumed operation of Union Pacific Railroad's City of San Francisco, City of Los Angeles, City of Denver, City of Portland and Challenger trains. The Midwest Hiawatha became two Sioux Falls-Chicago coaches that combined with the Challenger in Manilla. The Milwaukee Road dropped the name altogether in April 1956. North Woods Hiawatha The North Woods Hiawatha began in June 1936, branching off from the main Hiawatha route in New Lisbon, Wisconsin to serve Minocqua, Wisconsin. The Milwaukee Road dropped the Hiawatha moniker in 1956 and discontinued the service altogether in 1970. Olympian Hiawatha A new long-distance Hiawatha, the Olympian Hiawatha from Chicago to the Pacific Northwest, was inaugurated in 1947. The sleeper cars and Skytop sleepers were not delivered until late 1948 and early 1949, so the train ran with Pullman heavyweights on the rear end, until delivery of the new cars. The train was designed by the famous designer Brooks Stevens of Milwaukee. Six Creek-series 8-bedroom Skytop lounge-sleepers were created, which had more windows and a more bulbous rear end than their Rapids-series parlor Skytop counterparts on the Morning Hiawatha and Afternoon Hiawatha. This train ceased operations on May 22, 1961, and the surplus equipment was sold to Canadian National Railways. One car, #15 Coffee Creek from the Olympian Hiawatha, is undergoing restoration. Chippewa-Hiawatha The Chippewa began in May 1937, running north through Milwaukee and Green Bay to Channing, Michigan (later extended to Ontonagon). It carried the Hiawatha moniker between 1948-1957 and was discontinued in 1960. Amtrak Under Amtrak, which assumed control of most intercity passenger rail service in the United States on May 1, 1971, the Hiawatha name survived in two forms. The first was a Chicago–Milwaukee–Minneapolis service, known simply as the Hiawatha. This would be renamed the Twin Cities Hiawatha, then extended to Seattle and renamed the North Coast Hiawatha. This service ended in 1979. The second was a Chicago–Milwaukee corridor known as the Hiawatha Service (as opposed to Hiawatha). Although Amtrak had retained Chicago–Milwaukee service during the transition, it did not name these trains until October 29, 1972. At this time both Hiawatha and Hiawatha Service could be found on the same timetable. Amtrak used a variety of names for this service between 1976–1989 before returning to the Hiawatha Service brand, which remains today and continues to use
