City of Portland
- This article is about the passenger train City of Portland; for cities around the world, see the disambiguation page Portland.
The City of Portland was a named passenger train operated by the Union Pacific Railroad and Chicago and Northwestern Railway between Chicago, Illinois, and Portland, Oregon. In 1935, the railroad dedicated the refurbished M-10001 streamliner trainset to power the train. In 1955 the Milwaukee Road assumed the service, replacing the Chicago and Northwestern between Chicago and Omaha. The route roughly follows the trail of the defunct Amtrak route, the Pioneer.
