New Mexico, isolated until 1878 when the Atchison, Topeka, and Santa Fe Railroad laid the first span of track in the territory, in just thirty months had over 1,000 miles of rail line. Soon trains of freight and passenger cars, marvel of the industrial age, crisscrossed the territory delivering eastern fashion, settlers, and tourists and hauling away lumber, coal, silver, and cattle. The great railroad-building era in New Mexico ended with World War I, when eleven common carriers operated 3,000 miles of track. The subsequent history of New Mexico railroads is one of persistent struggle, slow eclipse, and corporate consolidation. But as this volume reminds us, steel rails, roaring engines, and clattering cars will always be a part of New Mexico's heritage.
