The T&P had a significant foothold in Texas by the mid-1880s. 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. However, due to outstanding bonds of the Missouri Pacific, the actual merger with the Union Pacific Railroad took place on January 1, 1997. Several reminders 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 warehouse still exists but there are plans to renovate it. The passenger terminal and corporate offices have been converted into luxury condominiums.
Major named passenger trains of the Texas and Pacific :

Texas Eagle -- St. Louis - various Texas points: western section going to El Paso, with connecting Southern Pacific service to Los Angeles; southwestern section to Laredo, with car change for Mexico City; southern section going to Houston
Westerner -- St. Louis - Dallas - El Paso -- connection in El Paso for Southern Pacific service to Los Angeles
"T&P" includes its subsidiary roads ; operated route-miles totalled 2259 at the end of 1929 and 2033 at the end of 1960.
Legal disputes
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.
From 1873 to 1881 the Texas and Pacific built a total of 972 miles of track; as a result it was entitled to land grants totalling 12,441,600 acres. T&P, however, received land only for the construction of track east of Fort Worth. This meant the firm received only 5,173,120 acres. The State of Texas did not award the additional area because, it said, the construction had not been completed within the time required by the firm's charter. The then state Attorney General Charles A. Culberson filed suit to recover 301,893 acres on the grounds that "the road had been granted land partly on sidetracks and partly on land not subject to location." The state ultimately recovered 256,046 acres giving a net grant to the T&P of 4,917,074 acres, or 7,683 square miles. By comparison, the state of Connecticut is 5,543 square miles.
The Texas Pacific Land Trust was created in 1888 in the wake of the bankruptcy of the T&P in order to provide an efficient and orderly way to sell the railway's land, receiving at the time in excess of 3.5 million acres. As of 31 December 2006 the Trust was still the largest private land owner in the state of Texas, owning the surface estate of 966,392 acres spread across 20 counties in the western part of the state. The Trust also generates income from oil & gas royalties through its 1/128 non-participating royalty interest under 85,414 acres and 1/16 non-participating royalty interest under 386,988 acres.
