San Pedro & Southwestern Railroad serves regional businesses in Cochise County from connections with Union Pacific’s Los Angeles- Chicago main line at Benson and Willcox, Ariz.
SPSR’s headquarters and Customer Service are based at Benson, 35 miles from Tucson—one of America’s fastest growing urban areas.
The San Pedro & Southwestern is owned by ARG Trans, which acquired the line in November 2003 from RailAmerica, Inc.
SPSR’s chief sources of traffic are agricultural chemicals, feed grains and building products. The line’s rail-to-truck transload facility at Benson offers customers savings from lower rail rates coupled with the convenience of truck delivery.
SPSR’s oldest predecessor dates to 1888, when the Arizona and South Eastern Railroad built a 60-mile line from Benson to Bisbee, eventually becoming part of the Southern Pacific. It was successively bought by Kyle Railways in 1992, StatesRail in 1997 and RailAmerica in 2002.
The railroad is laid with heavy 112-to-132 lb. rail, accommodating today’s heavier 286,000-lb. gross weight cars. SPSR replaced 3,000 crossties in 2007 and bridges were strengthened.
