Western and Atlantic 12 “Texas”, Steam locomotive at Atlanta History Center, United States.

The Western and Atlantic 12 "Texas" is a 4-4-0 "American" type steam locomotive built in October 1856 by Danforth, Cooke and Company of Paterson, New Jersey. It is displayed indoors on an upper-level platform inside the Cyclorama building at the Atlanta History Center, where visitors view it from the surrounding platform rather than entering the cab. Its smokestack was replaced with a diamond design for coal burning, and its cowcatcher was replaced with a wooden step for yard service.

Built in 1856 by Danforth, Cooke & Company, this engine chased Union raiders during the 1862 Great Locomotive Chase. This dramatic pursuit across Georgia railways became a key moment in Civil War military operations.

The engine's nickname comes from Texas, the state where the Western & Atlantic's president, John W. Thomas, had once worked. Its 1908 donation to the "Ladies of Atlanta" followed a campaign by the Atlanta Georgian newspaper, the United Daughters of the Confederacy, the Inman Park Students' Club and the Atlanta Woman's Club.

The Texas is displayed indoors on an upper-level platform inside the Cyclorama building at the Atlanta History Center, so it can be viewed in any weather. It is not operational and there is no cab access; visitors see it from the surrounding platform. Allow time to also see the Cyclorama painting in the same building.

The Texas carries a tender salvaged from another engine: the Dalton, built in 1864 by Mason Machine Works of Taunton, Massachusetts, sold to the Western & Atlantic after the war, renamed William MacRae and retired in 1890. Its tender was fitted to the Texas when the latter briefly returned to service in 1900.
