Missouri Pacific Railroad

On July 4, 1851, ground was broken at St. Louis on the Pacific Railroad, the predecessor of the Missouri Pacific Railroad. The first section of track was completed in 1852. Construction was interrupted by the American Civil War, but in 1865, it became the first railroad in Kansas City. In 1872, the Pacific Railroad was reorganized as the Missouri Pacific Railway by new investors after a railroad debt crisis. At one time, it advertised itself as "The First Railroad West of the Mississippi".

Other predecessors included the St. Louis, Iron Mountain and Southern Railway (SLIMS), Texas and Pacific Railway (TP), Chicago and Eastern Illinois Railroad (C&EI), St. Louis, Brownsville and Mexico Railway (SLBM), Kansas, Oklahoma and Gulf Railway (KO&G), Midland Valley Railroad (MV), San Antonio, Uvalde and Gulf Railroad (SAU&G), Gulf Coast Lines (GC), International-Great Northern Railroad (IGN), Kansas, Nebraska & Dakota Railroad, New Orleans, Texas and Mexico Railway (NOTM), Missouri-Illinois Railroad (MI), as well as the small Central Branch Railway (an early predecessor of MP in Kansas and south-central Nebraska), and joint ventures such as the Alton and Southern Railroad (AS).

Missouri Pacific was under the control of New York financier Jay Gould from 1879 until his death in 1892. Gould developed a system extending through Colorado, Nebraska, Arkansas, Texas, and Louisiana. His son George Gould inherited control upon his father's death, but lost control of the company after it declared bankruptcy in 1915. The line was merged with the St. Louis, Iron Mountain and Southern Railway (SLIMS) and reorganized as the Missouri Pacific Railroad in 1917. Missouri Pacific later acquired or gained a controlling interest in other lines in Texas, including the Gulf Coast Lines, International-Great Northern Railroad, and the Texas and Pacific Railway.

The railroad's first heavy repair shops were built in Sedalia, Missouri in 1872. In 1905 several smaller shop sites were consolidated at Sedalia when the old shops were closed and moved to a new site along Marshall Avenue. The MoPac began using SLIMS' Baring Cross Shops in North Little Rock, Arkansas, in 1882. A fire in 1900 caused them to be rebuilt on a larger scale that would ultimately become the primary MoPac shop site (now known as the Downing B. Jenks Shops). Minor locomotive repairs were carried out at the terminals in St. Louis and Kansas City.

MoPac declared bankruptcy again in 1933, during the Great Depression, and entered into trusteeship. The company was reorganized and the trusteeship ended in 1956.

By the 1980s, the system owned 11,469 miles (18,458 km) of rail line over 11 states bounded by Chicago to the east, Pueblo, Colorado, in the west, north to Omaha, south to the U.S.-Mexico border in Laredo, Texas, and southeast along the Gulf seaports of Louisiana and Texas. MoPac operated a fleet of more than 1,500 diesel locomotives, almost all purchased within the previous 10 years. Under the leadership of Downing B. Jenks, who became president and chief executive in 1961, the company became a pioneer in the early days of computer-guided rail technology. It was a major hauler of coal, grain, ore, autos, dry goods and shipping containers. At the time of its mega-merger in 1982, the MoPac owned more and newer locomotives and operated more track than partner Union Pacific Railroad.

On December 22, 1982, the Missouri Pacific was purchased by the Union Pacific Corporation and combined with the Western Pacific Railroad and Union Pacific Railroad to form one large railroad system. The corporation dubbed its rail subsidiary "Pacific Rail Systems", though all three railroads maintained their own corporate and commercial identity. The UP acquired the Missouri Kansas Texas and the Galveston, Houston & Henderson in 1988 and merged them into the Missouri Pacific on December 1, 1989.

By 1994, all motive power of the Missouri Pacific was repainted and on January 1, 1997, the Missouri Pacific was officially merged into the Union Pacific Railroad by the Union Pacific Corporation. UP continued to use the MoPac headquarters building at 210 N. 13th St. in downtown St. Louis for its customer service center until February 15, 2005. The former MoPac building has undergone rehab as apartments and is now known as Park Pacific.

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:

the Houstonian (between New Orleans and Houston);
