Formerly of the Klondike Mines Railway, then the White Pass & Yukon Route, followed by a few private owners, this locomotives is now going to be owned and operated by the new operation/museum at Como, Colorado. Little #4 just begs to be a prototype for an On30 locomotive!

Change the stack to a cabbage and swap the pilot out for foot boards and you have a great mainline runner for your logging operation!
Very similar to Eureka Nevada No. 7, which still survives today on a tourist operation in Idaho.
