This pair of relatively small Ten-wheelers had narrow, deep fireboxes offering considerable heating surface area behind high-mounted boilers. Their cylinders took steam from the boiler through 11" (279 mm) piston valves.
In 1906, the 100-mile long N&NW was bought by the Fort Dodge, Des Moines & Southern. The FDDM&S sold the two engines to the Chicago Iron Works. Apparently, the CIW sold the 12 directly to the Kettle Valley in 1913 as their 4, but sold the 10 to locomotive rebuilder/reseller Birmingham Rail & Locomotive, which sold it to the KV in October 1912.
The 4 went on to the Louisiana & North Western as their 27 in November 1921. The L&NW sold the 27 to locomotive rebuilder/reseller Southern Iron & Equipment in February 1926.
The buyer was credited as Bay De Noquet Lumber Company, which reflects the railroad's geographical location in Michigan's Upper Peninsula. Nahma (pronounced NAY-muh) sits on the south-facing bay near the head of Lake Michigan. The 4 made up part of the N & N's roster after the railroad began exploiting hardwood forests to the North. Ultimately, the N & N (aka the Whiskey Northern) encompassed 75 miles of track. Logging continued for almost 50 years before the railroad was abandoned in 1948.
This surprisingly high-drivered Ten-wheeler was bought by American Smelters Company for $13,139. After 30 years of service, the engine was retired in 1941.
In 1956, the NN revived the 40 to conduct railfan trips. In 1986, the NN donated the 40 to the State of Nevada in September 1986. The Nevada Northern Railway Museum operated the engine for a while, but ran into boiler life issues in 2001. http://www.nnry.com/40Rebuild/40Rebuild.htm, last accessed on 7 January 2012, narrates the long-running effort to restore the 40 to service. The work resulted in the "Ghost Train of Ely" returning to service in 2005.
Taken out of service in 2008 because of suspected cracks in the axles, the 40 sat cold until later analysis determined that the axles did not have actual cracks and thus could be operated safely. At the time of the 40's reappearance on the operational roster, however, the Museum understood that a $425,000-450,000 kitty needed to be assembled to completely overhaul the running gear.
