Atchison, Topeka and Santa Fe RailwayAKA: AT&SF, Santa Fe Railway, "The Santa Fe". Entered New Mexico in December 1878, reaching Albuquerque in April 1880. The AT&SF eventually served Arizona, California, Colorado, Illinois, Iowa, Kansas, Louisiana, Missouri, Nebraska, New Mexico, Oklahoma, and Texas. (Despite the name, it did not actually service Santa Fe directly, eventually utilizing a spur from Lamy 18 miles away.) Influential in opening New Mexico up to tourism, especially in conjunction with the Fred Harvey Company, with colorful advertisements attracting visitors from around the world. The AT&SF was also innovative, providing amenities to travelers such as dedicated dining and observation cars. Merged in 1996 to form the Burlington Northern and Santa Fe Railway.
