Class Details by Steve Llanso of Sweat House Media

Class Mogul (Locobase 2558)

See also Rogers Locomotive and Machine Works, "Locomotives and Locomotive Building" (New York: J W Pratt , Printer, 1876), p. 20; and John H White, Jr, A History of the American Locomotive: Its Development: 1830-1880 (New York: Dover Publications, 1979, p. 408.

Works number was 1235 in January 1865.

The first of the Mogul wheel arrangement, this Rogers design featured a variation of the basic Bissell truck. The company's Alba F Smith substituted swing links for the Bissell's inclined planes.

William Hudson used a compensating lever to connect the truck spring action to those of the equalized driver sets, noted the 1876 Rogers publication,"whereby both truck and driving wheels maintain their proper portion of weight, and accommodate themselves to the vertical, as wel as to the lateral, motion required to enable the engine to pass over uneven tracks, and around curves with ease as well as with perfect safety."

John H White, Jr., commented that Hudson's innovation had a dramatic impact. It was "so successful that in became the standard plan for all locomotives with single-axle trucks subsequently built in this country."

It later bore Pennsylvania Railroad road number 739.

As a light freight engine, the 2-6-0 proved quite popular and successful.
