Missouri Pacific Railroad

Union Pacific Corporation, the parent company of the Union Pacific Railroad, agreed to buy the Missouri Pacific Railroad on January 8, 1980. Lawsuits filed by competing railroads delayed approval of the merger until September 13, 1982. After the Supreme Court denied a trial to the Southern Pacific, the merger took effect on December 22, 1982. However, due to outstanding bonds of the Missouri Pacific, its full merger into the Union Pacific Railroad did not become official until January 1, 1997.

In the early years of the 20th century, most Missouri Pacific and St. Louis, Iron Mountain and Southern passenger trains were designated by number only, with little emphasis on premier name trains. This changed in May, 1915, with the inauguration of the Scenic Limited between St. Louis, Kansas City, and San Francisco. Between Pueblo, Colorado and Salt Lake City, the Scenic Limited operated through the Royal Gorge over the tracks of the Denver and Rio Grande Railroad. From Salt Lake City to San Francisco, the Scenic Limited operated over the Western Pacific Railroad. A second premier train, the Sunshine Special began operating on December 5, 1915, between St. Louis and San Antonio via Little Rock and Austin. Another named train, the Rainbow Special, was placed in service in July 1921 between Kansas City and Little Rock. The Sunshine Special soon eclipsed the other trains in travel volume, becoming the signature train of the Missouri Pacific Railroad. An advertising slogan in 1933 proclaimed: "It's 70-degrees in the Sunshine when it's 100-degrees in the shade," referring to the fact that the Sunshine Special was one of the first air-conditioned trains in the southwest. When new streamlined trains were delivered, the Scenic Limited and Rainbow Special names faded, but the Sunshine Special had sufficient name recognition to co-exist along with the new streamliners into the late 1950s.


In the streamliner era, the Missouri Pacific's premier passenger trains were collectively known as the Eagles. A variety of Eagle trains were operated, with the first such train inaugurated in 1940. These routes included the Missouri River Eagle (St. Louis-Kansas City-Omaha), the Delta Eagle (Memphis, Tennessee-Tallulah, Louisiana), the Colorado Eagle (St. Louis-Pueblo-Denver), the Texas Eagle (St. Louis to Texas), and the Valley Eagle (Houston-Corpus Christi-Brownsville, Texas).


Other notable MoPac trains operated included:


Missouri Pacific gained a reputation for aggressively discontinuing passenger trains after the mid-1960s. When the National Railroad Passenger Corporation (Amtrak) assumed passenger train operations on May 1, 1971, the only Missouri Pacific route included as part of Amtrak's basic system was its main line from St. Louis to Kansas City. This route is now served by Amtrak's Missouri River Runner (named for the fact that it runs mostly parallel to the Missouri River). On March 13, 1974, Amtrak restored passenger train service over segments of Missouri Pacific-Texas and Pacific's original Texas Eagle route between St. Louis, Little Rock, Dallas, Austin, San Antonio, and Laredo with the Inter-American. This train was renamed the Texas Eagle in 1981, resurrecting the name of the famous MoPac train. The Amtrak version runs over former MoPac and T&P trackage for much of its route.
