Kewaunee, Green Bay & Western 2-6-0 "Mogul" Locomotives in the USA

Class Details by Steve Llanso of Sweat House Media

Class R (Locobase 1352)

Data from photo and data supplied by Chris Hohl in his 24 January 2017 email in which he supplied tender capacities, loaded weight, and correct tube counts and length. Works numbers for these two engines were 54888 in September 1914 and 63139 in August 1921.

Seventeen 2-6-0s were built for the Green Bay & Western between 1907 & 1924, most with 175-lb boilers. Schenectady produced most of them, with Pittsburgh erecting some of the 250-256 run. The first group (27-30, 36-37) were built in 1907-1912. These were retired in 1936. Later engines, built from 1913-1924, were renumbered 250-260 in 1936. These went out of service gradually between 1939 and 1948.

After the Moguls been in service for a while, GB&W upgraded them with piston valves operated by Walschaerts gear and superheaters. Seven even had Nicholson thermic syphons installed in their fireboxes from 1925-1929.

Both of the KGB&W engines operated until 1945 with 258 being scrapped first in May 1945 and 257 following in July of the same year.
