Duluth, Mississippi River, & Northern 2-6-0 "Mogul" Type Locomotives

Data from 1899 Brooks Catalogue.

Builder info from B.Rumary, 25 Kingscombe, Gurney Slade, Radstock, BA3 4TH, ENGLAND and Jeremy Lambert as supplied by Allen Stanley in March 2004.

Works #2535 (July 1895), 2967 (May 1898). Both were sold to the Eastern Railway of Minnesota in 1899, but may never have actually operated on that road.

Medium Mogul with widespread drivers, steam dome over middle driver set, inversely tapered stack. Specifications say wagon top boiler, but the illustration suggests a Belpaire boiler.
