The City of Portland was a named passenger train on the Union Pacific Railroad between Chicago, Illinois, and Portland, Oregon. The first trip left Portland on June 6, 1935, using the streamlinedM-10001 trainset. With only one set of equipment, the train left each terminal six times a month. A broken axle derailed the trip that left Chicago on July 23, 1935, and the repaired train resumed service with the trip leaving Portland on February 6, 1936. In May 1936 it started running five times a month instead of six, allowing more time in Chicago between trips. (In July 1935 it was scheduled to arrive Chicago at 9:30 AM and leave at 6:15 PM the same day.)
It was the first streamliner with sleeping cars and the first streamliner running from Chicago to the Pacific coast; its 39-hour-45-minute schedule became the standard. (In April 1935 the fastest train took 59 hr 20 min Chicago to Portland.)[1] The M-10001 was withdrawn in March 1938 and replaced with another articulated trainset, the former City of Los AngelesM-10002. In July 1941 M-10002 was replaced with a train powered by the EMC E3 set inherited from City of Los Angeles pulling the former M-10004 cars, with some former M-10001 cars added. Service was expanded following the war as the train was joined, then replaced, by full-size trains powered by E6 and E7 locomotives. The train was the first of the 40-hour Coast streamliners to run daily, in February 1947. Starting in October 1955 the Milwaukee Road was used instead of the Chicago and North Western between Chicago and Omaha; from January 1959 until 1967 the train ran via Denver. The train was discontinued May 1, 1971, with the takeover of Union Pacific's passenger services by Amtrak. The route roughly follows the trail of the defunct Amtrak route, the Pioneer, except that the latter diverted to Ogden, Utah, while the City of Portland did not enter Utah.[2]
