I photographed this 1944 American Locomotive Company (ALCO) 2-8-4 Kanawha K-4 Chesapeake and Ohio Railway #2736 at the National Train Museum in Green Bay, Wisc.
This type was usually known as the Berkshire class, but the Chesapeake and Ohio Railway named their engines Kanawha after the river that cut through the railroad’s operational heartland in West Virginia.
