Kewaunee, Green Bay & Western 2-8-0 "Consolidation" Locomotives of the USA

Class Details by Steve Llanso of Sweat House Media

Class Z (Locobase 13558)

Data from 1947 diagram reproduced on the Green Bay Route website at, last accessed 20 December 2011. Works numbers were 64127-64128 in January 1923.

The KGB & W was 2/3s owned by the Green Bay & Western from 1897 on. The road was begun in 1890 to create a year-round connection between Green Bay and the East. Over the years, according to the web site, the ferry system connecting Kewaunee and the cities of Frankfurt and Ludington on the Michigan mitten proved invaluable to the Green Bay Route in its provision of time-sensitive traffic between Lake Michigan and the Mississippi River.

Brooks delivered one of these Consolidations to the KGB & W as their 45 (priced at $33,450) and one to the GB & W as their 65. 45 (later 398) was the most powerful engine on the KGB & W. After its 25-year career on the railroad ended in 1948, it was sold to the Ahnapee & Western. The A & W renumbered it 261, but used it only sparingly and sold it to the Detroit, Cairo & Sandusky in December 1950. It was scrapped in 1953.

65 remained on the GB & W until it was scrapped in 1951.
