Terre Haute & Indianapolis 4-6-0 "Ten-Wheeler" Type Locomotives

Data from Traite pratique de la machine locomotive ... By Maurice Demoulin, 1898

Librairie polytechnique, Baudry et Cie, p 384

Locobase believes that this is in fact a TH & I locomotive from the mid-1890s, but cannot find it listed in the Rumary list of Pittsburgh-built engines. Demoulin offered this engine as an faithful example (representant fidelment) of the 6-coupled, high-speed locomotive used in America. He reported tonnage ratings at 65 km (40 mph) as 513 tons on the level. (Other figures included 363 tons up 0.3% grade, 272 tons up 1/2%, 163 tons up 0.8%.
