By the late 1800s, the major mode of transportation for travelers to the Southwest was by rail. In 1878, the Atchison, Topeka, and Santa Fe Railway Company (AT&SF) became the first railroad to enter New Mexico, and by the late 1890s it controlled more than half of the track-miles in the Territory. The company wielded tremendous power in New Mexico, and soon made tourism an important facet of its financial enterprise.
