This map, based on an 1885 traveler’s guide published by the Atchison, Topeka, and Santa Fe Railroad, includes the company’s U.S. lines and also those of its Mexican Central Railroad, an ATSF subsidiary that crossed the border and terminated at Guaymas and Mexico City, Mexico. The dots represent the many stops that the trains made along the routes between major cities. Most Mexican railroads in this era were built and operated by U.S. companies. As you analyze this map, consider how residents of the two countries may have experienced the railroad’s arrival in different ways.
