In 1948, the Missouri Pacific Railroad inaugurated a new streamlined train, the Texas Eagle, running between St. Louis and either El Paso, Laredo, or Houston, Texas. The name fit in with Missouri Pacific's general train naming scheme, which also included such trains as the Colorado Eagle (St. Louis to Denver via Pueblo) and the Missouri River Eagle (St. Louis to Omaha).

The Texas Eagle did not survive Amtrak's 1971 takeover of most passenger train service in the United States, but in 1973, Amtrak began operating a train over a portion of the route between Fort Worth and Laredo called the Inter-American, with a connection available at Fort Worth for service to Chicago on the Texas Chief (later renamed the Lone Star).

Within a couple of years, the Inter-American had been extended to St. Louis over the old Texas Eagle route, running three days a week, and then extended to Chicago in 1976. When the Lone Star was discontinued in 1979, a Houston section was added to the now daily Inter-American, with the train splitting and combining in Temple.

In the early 1980s, the train returned to a 3-day-a-week schedule, the Houston section was eliminated, and the remaining portion was cut back to a southern terminus at San Antonio. Departure and arrival times were changed to allow for the operation of a through sleeping car to Los Angeles, carried on the Sunset Limited. With these changes, the train was renamed the Eagle.
