Texas and Pacific Railway

The Texas and Pacific Railway Company (known as the T&P) was created by federal charter in 1871 with the purpose of building a southern transcontinental railroad between Marshall, Texas, and San Diego, California. However its lines never went west of El Paso, near where in 1881 it connected to the Southern Pacific line to California.

Under the influence of General Buell, the T&P was originally to be 3 ft 6 in (1,067 mm) gauge, but this was overturned when the state legislature passed a law requiring 4 ft 8+1⁄2 in (1,435 mm) gauge.

The T&P had a significant foothold in Texas by the mid-1870s. Construction difficulties delayed westward progress, until American financier Jay Gould acquired an interest in the railroad in 1879. The T&P never reached San Diego; instead it met the Southern Pacific at Sierra Blanca, Texas, in 1881.

The Missouri Pacific Railroad, also controlled by Gould, leased the T&P from 1881 to 1885 and continued a cooperative relationship with the T&P after the lease ended. Missouri Pacific gained majority ownership of the Texas and Pacific Railway's stock in 1928, but allowed it to continue operation as a separate entity until they were eventually merged on October 15, 1976. On January 8, 1980, the Missouri Pacific Railroad was purchased by the Union Pacific Railroad. Because of lawsuits filed by competing railroads, the merger was not approved until September 13, 1982. Due to outstanding bonds of the Missouri Pacific, though, the actual merger with the Union Pacific Railroad took place on January 1, 1997.

Several parts of the Texas and Pacific remain to this day, mainly two towering buildings, which help define the southern side of Fort Worth's skyline—the original station and office tower and a warehouse located immediately to the west. In 2001, the passenger platforms at the T&P station were put into use for the first time in decades as the westernmost terminus for the Trinity Railway Express, a commuter rail line connecting Fort Worth and Dallas. The T&P Warehouse still exists, but remains vacant with no plans to renovate it despite significant civic support and third-party developer interest. The passenger terminal and corporate offices have been converted into luxury condominiums.

Major named passenger trains of the Texas and Pacific (route sections between St. Louis and Texarkana were operated by Missouri Pacific):

"T&P" includes its subsidiary roads (A&S, D&PS, T-NM etc.); operated route-miles totalled 2259 at the end of 1929 (after C&NE, PVS and TSL had become subsidiaries) and 2033 at the end of 1960.

The Texas and Pacific was unable to finance construction to San Diego, and as a result the Southern Pacific was able to build from California to Sierra Blanca, Texas. In doing so, Southern Pacific used land designated for, and surveyed by Texas and Pacific, in its rail line from Yuma, Arizona, to El Paso, Texas. This resulted in lawsuits, which were settled with agreements to share tracks, and to cooperate in the building of new tracks. Most of the features advantageous to Texas and Pacific were later disallowed by legislation.
