Union Pacific 844 is a 4-8-4 steam locomotive owned by Union Pacific Railroad. Built in 1944, it was the last steam locomotive delivered to Union Pacific and is the only steam locomotive never retired by a North American Class I railroad.
Union Pacific 844 was one of 10 locomotives that were ordered by Union Pacific in 1944 and designated as class FEF-3. The FEF-3 class represented the epitome of dual-service steam locomotive development; funds and research were being concentrated into the development of diesel-electric locomotives. Designed to burn coal, they were converted to run on fuel oil. Like the earlier FEF-2 class, FEF-3 locomotives were designed as passenger engines. They pulled such trains as the Overland Limited, Los Angeles Limited, Portland Rose and Challenger.
Some enthusiasts think UP 844 could pull 26 passenger cars at more than 100 mph (161 km/h) on straight and level track; they say it was designed to safely operate up to 120 mph (193 km/h) with its one-piece cast-steel bed frame, 80-inch (2,032 mm) drivers, massive boiler/firebox and lightweight reciprocating parts, which were common on late-era steam locomotives. (UP's timetables showed a speed limit for steam locomotives of 80 mph.)
From 1957 to 1959, UP 844 was reassigned to freight service in Nebraska when diesel-electric locomotives took over passenger service.
Saved from scrapping in 1960, UP 844 was chosen for restoration and is now used on company and public excursion trains, along with revenue freight during ferry moves.
Excursion career 
Since 1962, the engine has run hundreds of thousands of miles as Union Pacific's ambassador of goodwill. It appeared at Expo ’74 in Spokane, the 1978 dedication of the Utah State Railroad Museum in Ogden, Utah, the 1981 opening of the California State Railroad Museum in Sacramento, the 1984 World's Fair in New Orleans and the 50th Anniversary Celebration of Los Angeles Union Station in 1989. It has performed a side-by-side run with Southern Pacific 4449. On February 14, 1975, it pulled Amtrak's San Francisco Zephyr from Denver, Colorado, to Cheyenne, Wyoming, with a pair of EMD SDP40Fs.
Over the weekend of October 14, 1990, the UP 844 led a procession of special trains from Kansas City Union Station to Abilene, Kansas, for WWII veterans to celebrate the 100th birthday of President Dwight D. Eisenhower. The “Eisenhower Centennial Special” was a collaboration between the Union Pacific, Burlington Northern and Santa Fe Railroad business fleets, with additional passenger cars provided by the Norfolk Southern and Chicago North Western railroads. Present also in Abilene was General Eisenhower’s command train, code-named "Bayonet", including the British A4 steam locomotive #60008, communication and staff cars from WWII European Theater Operations. The UP 844 consist for that weekend included 21 units, including the tool and power car, a super dome and regular dome, lounge and observation, concession/baggage cars and chair cars in the following order: Columbia River, Western Lodge, Sunshine Special, Sun Valley, Texas Eagle, Portland Rose, City of Los Angeles, Challenger, Columbine, Western Special, Powder River, St. Louis, Iowa River, Harriman, Cheyenne, Cedar River, Chicago, Minnesota and Fox River.
On May 18, and May 19, 2007, the 844 made another rare appearance with Southern Pacific 4449 in the Pacific Northwest for the "Puget Sound Excursion", on the Burlington Northern Santa Fe railroad tracks from Tacoma to Everett, round-trip. This excursion was a tandem run; the locomotives pulled a Union Pacific passenger train consisting of three to four dome cars and several coaches.
Today, UP 844 runs occasional excursion and fan trips along UP trackage every year. On June 25 and 26, 2010, the 844 made an excursion trip to the Milliken, Colorado, Centennial Celebration. On rare occasions, it has been, and still can be used in revenue service.
In fall 2010, the Union Pacific allowed railfans to vote where the coming season's excursion trains will operate.
In September 2012, the 844 participated in UP 150, a celebration of Union Pacific's 150th anniversary celebration, hosted by the California State Railroad Museum in Old Sacramento, California. During the event, 844's tender derailed on tightly curved track from the mainline to the museum. Later in 2012, Union Pacific officials said they were trying to acquire the 4-8-8-4 Big Boy 4014 for restoration and operation.
Union Pacific "8444" 
From 1962–1989, the locomotive was numbered UP #8444 because the railroad had given 844 to a EMD GP30 locomotive. After the GP30 was retired from service in June 198 (it remains operable), 8444 was renumbered back to 844. There is now an EMD SD70ACe in UP's roster numbered 8444.
Surviving sister engines 
A second 4-8-4 of the same class, UP 838, is kept in the shops at Cheyenne, Wyoming, as a source of spare parts. It is said[by whom?] that 838's running gear and boiler are in much better condition due to 844's extensive use.
Film history 
In the 1990 PBS special Ghost Trains of the Old West, 8444, as it was numbered at the time of filming, is seen pulling a Union Pacific diesel locomotive and passenger train through Wyoming at about 75 mph.
Numbered as 8444, the locomotive was featured on a trip from Cheyenne, Wyoming to Los Angeles, California in the 1989 documentary film "Steam To Los Angeles"
