In 1880 the Atchison Topeka and Santa Fe railroad came to Albuquerque. But more importantly, the company located its locomotive repair shops in the town. This would change the city forever. At their height the locomotive shops employed 2,000 people. The quadrant system for Albuquerque addresses actually originated with this giant facility. In the book from University of New Mexico Press, Richard Flint and Shirley Cushing Flint explore how these shops became the catalyst for the modern city.
