The Nothern Pacific Railway's first locomotive was the "Minnetonka", a Smith & Porter 0-4-0 built in 1870, and used in the construction of the railroad as it started west from Carlton, MN. The engine was later sold to a logging company, and spent many years hauling logs before being repurchased by the NP for preservation. She is still owned by the NP's successor, the Burlington Northern/Santa Fe, and in recent years spent some time on display at the company's headquarters in Fort Worth, Texas. Happily, she is now back home at the Lake Superior Railroad Museum in Duluth.
