Central of Georgia Diesel Locomotive Roster

-
Links PDF of the Central of Georgia Roster . Description This is a nine-page detailed roster with a full bibliography. This is the final completed version of this project. The roster began with compiling a roster distilled from Diesels of the Southern Railway 1939-1982 by Paul K. Withers, Warren L. Calloway and J. Harlen Wilson. This compiled roster was compared to the Alco , Baldwin , and  Fairbanks-Morse  builder's lists found on this blog and the primary source EMD Locomotive Reference Data . Those provided accurate builder's dates (actually the shipping dates that all builders use as the builder date) and order numbers. Locomotive classes were derived from Central of Georgia locomotive diagram books of various dates.

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

EMD SW600 Phase Guide and Builder List

-
 EMD's SW600 was the six-hundred horsepower successor to the SW1. Three new models were introduced in 1954 - the SW600, SW900, and SW1200. EMD built 1,056 of their 1200-horsepower SW1200 model. The SW900, at 900 horsepower, sold reasonably well at 372. The customer base for that model was industry and a few Class I roads with light-duty branch line applications. But the little SW600? Just 15 units for 13 different customers with no repeat orders. Six hundred horsepower units were a niche market by this time. Long gone were the robust sales of the SW1. Customers were few, mostly oil refiners, chemical plants, coal-fired electrical power plants, and rarely, a steel producer.  The only Class I customer was Chicago & North Western, buying just two units. By the time the 645-powered switchers were introduced, EMD could no longer justify including a six-hundred horsepower model because the margins were too low. Here's a link to the .pdf.

General Electric U28C phase guide and builder's list

-
The U28C was a bridge model between the 2500 hp U25C and the highly successful U30C. The 2800 hp rating was a bit of a disadvantage compared to Alco's C630 and EMD's SD40, and the model remained in production for just over a year. Within months of the start of production, GE completely re-engineered the Universal Series with a new frame, car body, equipment layout, and in the case of the six-axle units, the new FB-3 floating bolster truck. Here's the link to the .pdf of the phase study and builder's list.

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. Here's the link to the .pdf

EMD GP20 Phase Guide and Builder's List

-
  EMD's GP20 was cutting-edge technology in 1959 when the first unit was sold to the Western Pacific.  The builder was loathe to risk the sacrifice of its rock-solid engineering reputation on the altar of unproven technology.  Railroads, however, were having none of it. The horsepower race was well underway. Wealthy customers were already blazing new ground, EMD in tow or not. Union Pacific was happily buying General Electric gas turbines that dwarfed the power of the GP9/GP18. The railroad was also adding turbochargers to their existing GP9 fleet. Southern Pacific and the Denver & Rio Grande Western were importing complex and exotic diesel hydraulics from Germany that had unheard of adhesion and horsepower.   If that wasn't bad enough, General Electric was ready to introduce the 2500 horsepower U25B that had been long under development. Reluctantly, then, EMD introduced the SD24 and the GP20, unfortunately just as a severe recession was getting started....
