Wolfgang das ist fuer Dich. No. 844 was the last steam locomotive built for Union Pacific Railroad. It was delivered in 1944. A high-speed passenger engine, it pulled such well-known trains as the Overland Limited, Los Angeles Limited, Portland Rose and Challenger trains. When diesel locomotives took over pulling passenger trains, No. 844 was placed in freight service in Nebraska between 1957 and 1959. It was saved from being scrapped in 1960 and held for special service. This engine has run hundreds of thousands of miles as Union Pacific's ambassador of goodwill. It has made appearances at Expo '74 in Spokane, 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.
