The Braden Copper Company that operated the Teniente copper mine in Chile was a big user of Shays. In addition to ten 42-ton two-truck Shays, they also had six 60-ton three-truck models. Five were built between 1914 and 1918 and the sixth one followed in 1929. Numbers 10 and 12 were built as coal burners, all others were directly delivered as oil burners.
Empty weights of the individual locomotives are being given between 95,000 and 110,000 pounds. Numbers 19 and 20 collided in 1935. Number 14, built in 1916 as Shay works number 2876, was the longest-living. It came to Codelco in 1970 and today is on static display at Rancagua.
