Sumpter Valley Railway 2-8-2 #19 at the Portland Union Station Centennial

Sumpter Valley Railway #19 is the first of a pair of narrow-gauge 2-8-2 Mikados built for the eastern Oregon railroad by the American Locomotive Company in 1920. #19 & #20 were replaced on the Sumpter Valley in 1940 by a pair of used Baldwin articulated 2-6-6-2 Mallets. The tenders from the Mikados were put behind the Mallets, and the Mikados were sold to Alaska's White Pass & Yukon, where they served until 1957. The Mallets were sold to a railroad in Guatemala in 1947, and the tenders went with them. The Sumpter Valley reacquired the two Mikados in the 1970s and got the tenders back from Guatemala.

#19 was restored at the Brooklyn Roundhouse in Portland, Oregon, in the early 1990s. It had recently been completed and was brought to Union Station's 100th Anniversary on May 11, 1996, before being returned to the Sumpter Valley. A section of track at Union Station was converted to the narrow 3-foot gauge to allow #19 to be fired up and operate back and forth.

Chicago & North Western Inspection Car #420 "Fox River"

Chicago & North Western Inspection Car #420, Fox River, was built by Pullman-Standard in 1954 as Canadian National Sleeper-Lounge Car #1087, Cape Breton. It was later transferred to VIA Rail and remained in service in Canada until 1983, when it was sold to Rail Travel Associates. It was sold to Milwaukee Rail Car in 1984, and was rebuilt into C&NW Inspection Car Fox River in 1985.

Union Pacific acquired the car when it absorbed the C&NW in 1995. Union Pacific had the car remodeled in 1997 and painted in UP colors and still uses it today.

Union Pacific Dome Lounge Observation #9009 "City of San Francisco"

Union Pacific Dome Lounge Observation #9009, City of San Francisco, was built by American Car & Foundry in April 1955 for use on the City of Portland. The car was sold to AutoTrain in May, 1972 for use between Virginia and Florida, becoming AutoTrain #908. After AutoTrain shut down in April 1981, the car was sold in December but was never paid for. It moved through several owners seeing little use until becoming Scenic Rail Dining's Rivers Edge in 1987 and being used in dinner train service. It became Transcisco Tours' Zephyr Cove in 1991 and was used on the Kalamazoo, Lake Shore & Chicago's Wine County Dinner Train. Union Pacific re-purchased the car in May of 1993. After being refurbished, the car was given the name City of San Francisco, after the jointly operated Union Pacific/Southern Pacific/Chicago& North Western streamliner that ran between Chicago and Oakland, California from June 1936 to April 1971. Incidentally, due to clearances on the Southern Pacific portion, Union Pacific's dome cars were not used on the City of San Francisco.

Chicago & North Western Full Dome #421 "Powder River"

Chicago & North Western Full Dome #421, Powder River, was built by Pullman-Standard in 1952 as Chicago, Milwaukee, St. Paul & Pacific Super Dome #53. It was sold to Canadian National in 1965, becoming #2401, Athabasca, and was later transferred to VIA Rail, remaining in service in Canada until 1982 as #2701. After going through a series of owners, it was purchased by the C&NW in 1985. Union Pacific acquired the car when it absorbed the C&NW in 1995. This was one of the few excursions it was used on before UP sold it to the North Carolina Department of Transportation in 1996. The Friends of the 261 purchased the car from NCDOT in 2005 and restored it to Milwaukee Road colors.

Union Pacific Dome Dining Car #8008 "City of Portland"

In June 1972, the car was sold to AutoTrain for use between Virginia and Florida, becoming AutoTrain #807. After AutoTrain shut down in April 1981, the car was sold to A. J. Daniels of Tulsa, Oklahoma in December 1981, and was subsequently sold to Kansas City Southern via Mid-America Car Company in 1982. The car was assigned KCS #19 and was intended for use on a revived Southern Belle passenger train that was aborted. The car remained in storage in AutoTrain paint at Mid-America Car Company in Kansas City until being re-purchased by Union Pacific via Northern Rail Car in October 1990. After being refurbished, the car was given the name City of Portland, after the jointly operated Union Pacific/Chicago & North Western streamliner that ran between Chicago and Portland, Oregon from June 1935 to April 1971.

Union Pacific Dome Coach #7015 "Challenger"

Union Pacific Dome Coach #7015, Challenger, was built by Pullman-Standard in November 1958 as part of Pullman-Standard's last group of dome cars: five for Union Pacific's City of St. Louis and one of the same design for the Wabash railroad. This was the last of the Union Pacific cars, and was originally assigned to service on the City of St. Louis, a train operated jointly with the Wabash (the one car built for Wabash was also assigned to this service). In June 1972, the car was sold to AutoTrain for use between Virginia and Florida, becoming AutoTrain #702. (It is rumored that before being sold to AutoTrain, it was accidentally shipped to Alaska with a group of cars that had been purchased by the Alaska Railroad, and had to be sent back, but this has not been verified) After AutoTrain shut down in April 1981, the car was sold to A. J. Daniels of Tulsa, Oklahoma in December 1981, and was subsequently sold to Kansas City Southern via Mid-America Car Company in 1982. The car was assigned KCS #22 and was intended for use on a revived Southern Belle passenger train that was aborted. The car remained in storage in AutoTrain paint at Mid-America Car Company in Kansas City until being re-purchased by Union Pacific via Northern Rail Car in October 1990. After being refurbished, the car was given the name Challenger, after Union Pacific's all-coach Challenger train that ran between Omaha, Nebraska and Los Angeles, California from May 1936 to April 1971.

Union Pacific Power Car #208

Union Pacific Power Car #208 was originally built by American Car & Foundry in 1949 as Baggage-Dormitory #6006. In 1962, it was one of five such cars Union Pacific remodeled into Boiler-Dormitory-Baggage cars to provide additional heating capabilities in extremely long passenger trains and renumbered to #303. In 1987 it was assigned to the steam program as #209. In 1991, the car was equipped with a diesel generator to supply Hotel Electric Power (HEP) to other cars. This car has the unusual configuration of a four-axle truck on one end and a six-axle truck on the other.
