Cananea Consolidated Copper Company 4-6-0 Locomotives in Mexico


Class Details by Steve Llanso of Sweat House Media

Class W C Greene (Locobase 12587)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 24, p. 146. Works number was 19912 in December 1901.

Cananea Consolidated Copper Company was established in Sonora to exploit over 7,000 acres of copper-bearing ground. The locomotive was named after the company's President.

After an epic 1906 strike at the mines, the railway was reincorporated as the Cananea Rio Yaqui & Pacific.

NB: Locobase estimates the heating surface areas based on the virtually identical design supplied to the Cumberland Construction Company and described in Locobase 12396.
