The Atchison, Topeka and Santa Fe Railway (reporting mark ATSF), often abbreviated as Santa Fe, was one of the larger railroads in the United States. The company was first chartered in February 1859. Although the railway was named in part for the capital of New Mexico, its main line never reached there as the terrain made it too difficult to lay the necessary tracks (Santa Fe was ultimately served by a branch line from Lamy, New Mexico). The Santa Fe's first tracks reached the Kansas/Colorado state line in 1873, and connected to Pueblo, Colorado in 1876. In order to help fuel the railroad's profitability, the Santa Fe set up real estate offices and sold farm land from the land grants that the railroad was awarded by Congress; these new farms would create a demand for transportation (both freight and passenger service) that was offered by the Santa Fe.
