What is the distance from Chicago to San Antonio?

Amtrak's Texas Eagle is the direct successor of the Missouri Pacific Railroad and Texas and Pacific Railway train of the same name, which was inaugurated August 15, 1948. For thirteen years, the Texas Eagle operated as two separate sections, leaving St. Louis in the late afternoon, one following behind the other at an approximately 10 minute interval. At Longview, the routes diverged. The west Texas section continued to Dallas and El Paso, while the south Texas section operated to Austin and San Antonio, where a connection was made to the Aztec Eagle for Laredo and Mexico City. After 1961, the Texas Eagle was consolidated as a single, very long train, between St. Louis and Longview, Texas, where the train was split into several sections, each serving different Texas cities. The west Texas section of the Texas Eagle continued from Longview to Dallas, Fort Worth, and El Paso; the south Texas section served Palestine, Austin, San Antonio, and Laredo, with a through Pullman continuing to Mexico City. A third section of the Texas Eagle split from the main train at Palestine, providing service to Houston.
