Georgetown & Western / Great Western 2-8-0 "Consolidation" Locomotives of the USA


Class Details by Steve Llanso of Sweat House Media

Class 121 (Locobase 15116)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 43, p. 142+. Works number was 39425 in March 1913.

This freight Consolidation joined the G&W only two years before it was merged with Seaboard subsidiary Carolina, Atlantic & Western, which rolled into the Seaboard itself by the end of 1915.

Sold to the Lightsey Brothers, the 121 was lettered in 1937 for the Hampton & Branchville. It served the H&B until placed in storage in 1955.


Class 51 (Locobase 12988)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 29, p. 132. Works numbers were 28665, 28676 in July 1906.

This pair of Consolidations operated on the independent sugar-beet railroad until they were retired in the 1950s. 52 retired in April 1952 and scrapped while 51 lingered to be sold to Boulder Scientific in 1963. According to Wes Barris's Surviving Locomotives website, the 51 wound up operating on the Fillmore & Western Railway in Fillmore, Calif, from which it was bought by Jim Birmingham and moved back to Hudson, Colo.


Class 60 (Locobase 4811)

Data from http://www.brwrr.com/brwsp60.htm website.

The majestically named Great Western Railway of Colorado linked Eaton and Longmont (north of Denver) over 42 miles of track that chiefly saw sugar beet traffic. So a sturdy light Consolidation of typical American design would fill the bill just fine. One correspondent writes of seeing GW trains passing through the middle of his farm in Windsor and refers to 60 in particular.

This particular engine later wound up on the Black River & Western Railroad of western New Jersey for excursion operations.

NB: The direct heating surface (including the firebox heating surface) is an estimate calculated by subtracting the calculated tube heating surface from the reported total evaporative heating surface.


Class 75 (Locobase 13169)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 30, p. 279. Works number was 31778 in September 1907.

Like the other locomotives procured for this private Colorado sugar-beet road, the 75 remained in service until the road was closed. In storage for years, the 75 was sold to the National Railroad Historical Society in December 1966. It was then stored at Rocky Mountain Arsenal.
