The AZER network comprises the Lordsburg - Duncan - Clifton and Bowie -
San Carlos - Miami lines, which total 320km. The railway also has
running rights on an 84km stretch of Union Pacific's El Paso - Tucson
main line between Lordsburg and Bowie, which links the two branches.

AZER's principal customer is copper producer Freeport-McMoran, and the
railway serves the company's largest North American mine and smelter.
As part of the sale, AZER has entered a long-term agreement with
Freeport-McMoran which will result in service and track upgrades.

AZER has 10 locomotives and 45 employees, and will be incorporated into
G&W's Mountain West Region, which also includes the Utah Railway
and coal operations in the Powder River Basin of Wyoming and Montana.
