The Atchison, Topeka and Santa Fe Railway (often referred to as the Santa Fe or AT&SF) was a large railroad in the United States. Created in February 1859, the railroad reached the Kansas-Colorado border in 1873 and Pueblo, Colorado, in 1876. To create a demand for its services, the railroad set up real estate offices and sold farm land. Despite the name, its main railroad never served Santa Fe, New Mexico. This was because the terrain was too rough. A branch line from Lamy reached Santa Fe instead.
