EMD SW7 Phase Guide and Builder's List

-

 

EMD replaced the 1,000 horsepower NW2 with the 1,200 horsepower SW7 in October, 1949. The SW7 continued to be built until it too was replaced by the SW9 in November, 1950. There was some overlap in production, until January, 1951.

This was a popular locomotive, and EMD could not keep up with demand. Southern Pacific wanted to place significant orders but had to settle for just four units for the Cotton Belt because of long lead times.

Phelps Dodge Corporation Diesel Locomotive Roster

-
  Phelps Dodge Corporation was one of the largest copper producers in the United States, with operations in Ajo, Douglas, Bisbee, and Morenci, Arizona, and Hidalgo, New Mexico.  The company had extensive rail operations in the open-pit mines at the New Cornelia Branch, Morenci Mines, and Lavender Pit. It operated two fairly long rail lines, the Tucson, Cornelia & Gila Bend between Ajo and Gila Bend, Arizona, and later, from Separ to Hidalgo, New Mexico. The roster is very complex. Transfers in the early years were frequent. David F. Myrick took six volumes to document the railroads of Arizona and died before completing the work. P. Allen Copeland completed a masterful set of Arizona shortline and industrial rosters for volume three, and this work updates, corrects, and clarifies the multiple rosters for Phelps Dodge. Here's a link to the completed work, revised to March 13, 2022 at 6:40 a.m. MST
