AZ AA:10:19(ASM)
This number encompasses extant portions of the Arizona Southern Railroad, only some of which were found on ASARCO and BLM lands. A subsidiary of the Imperial Copper Company at its inception, the railroad was incorporated in January 20, 1904. William Staunton of Imperial headed up the initiative and contracted Grant Brothers of Los Angeles to build the line. Construction commenced on February 17, 1904. Crews totaling 600 to 700 men laid approximately 22 miles of standard gauge track between Red Rock and Silver Bell. The hilly terrain around Silver Bell necessitated a series of switchbacks over the last two miles and a wye for turning locomotives; a maximum grade of 3.4% was attained at Jesuit Hill. Two trestles spanned Silver Bell Wash, one at Jesuit Hill and one in Silver Bell itself. The latter had a wagon road beneath it. The line was completed on September 1, 1904.

The Arizona Southern Railroad served a dual purpose: it hauled ore to Red Rock, at which point it was taken via the Southern Pacific Railroad to Douglas or other smelters, and it provided water, mail, freight, and passenger service between Red Rock and Silver Bell. Passengers transferred to the Southern Pacific line at Red Rock. After 1907 ore was hauled directly to the smelter at Sasco. Prior to the building of the railroad, people and supplies traveled by train to Rillito, Red Rock, or Picacho, and completed the journey to Silver Bell by stage, buggy, or horse (a Tucson to Silver Bell stage ran from about 1881 to 1901, and a subsequent “auto stage” operated until the early 1930s). Mining company correspondence from the pre-rail period indicates that hauling freight to the district was an extremely precarious business, and many shipments were lost or late due to inclement weather and high water in the Santa Cruz River.

The railroad maintained locomotives, cabooses, flatbeds with water tanks, freight cars, passenger cars, and a series of special automobiles that were modified to travel by rail. The first two track cars were Cadillacs, followed by an Oldsmobile and a Buick. These track cars allowed company managers to travel to and from the mines more expeditiously, as they did not have to wait for scheduled trains. Oral histories suggest that the community was quite fascinated with these vehicles, one of which was dubbed “the Speeder.”

Imperial’s bankruptcy forced a temporary suspension of service in 1914 and 1915, but ASARCO resumed intermittent operation and even added track at Sasco in 1917. By December 20, 1933, however, ASARCO had received permission to abandon the line; ten days later, the tracks were dismantled and everything was sold.

Archaeologists identified the wye, several switchbacks, retaining walls, and wooden culverts, many of which remained in good condition in the early 1990s. Segments of track were still extant near ASARCO’s Dump No. 10, and a few railroad spikes were encountered in the area. To the north, the railroad grade served as a county road.

Unfortunately, features, trash, or other evidence of railroad construction camps were not evident to field personnel. Their report surmises that construction crews may have been housed in box cars.
