The Copper Basin Railway (reporting mark CBRY) is an Arizona short-line railroad that operates from a connection with the Union Pacific Railroad (UP) at Magma to Winkelman, in 54 miles (87 km) of length.

L. S. “Jake” Jacobson was the President and Chief Operating Officer, retiring in 2020 after more than 30 years in his position.

107,000 cars per year (1996 estimate)[citation needed] The Magma–Winkelman line was constructed by the Atchison, Topeka and Santa Fe Railway (ATSF) subsidiary Phoenix and Eastern Railroad between 1902 - 1904.

It originally proposed to build to a connection with the Southern Pacific Railroad (SP) at Benson but the line was never built past Winkelman.

This railway served as the backdrop to Dwight Yoakam’s “A Thousand Miles from Nowhere” music video.
