Huntingdon & Broad Top Mountain 4-6-0 "Ten-Wheeler" Locomotives in the USA

Class 27 (Locobase 12431)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Vol 23, p. 64. Works number was 17925 in July 1900

Like most of the H & BTM motive power, the 27 spent all of its career on its original railroad. It was a big mixed-traffic Ten-wheeler.

Class 35 (Locobase 14687)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Vol 65, p. 152. Works numbers were 55031-55032 in September 1921.

The previous Baldwin Ten-wheeler on this road was the 27, delivered in 1900 (Locobase 12431). These two engines were a full generation or two younger and were ticketed for the H&BTM's passenger service. The addition of a superheater, together with a slightly higher boiler pressure and no signficant change in cylinder volume, more than offset the effect of taller drivers on tractive effort. The valve gear moved outside the frames and actuated 12" (305 mm) piston valves. The firebox's heating surface area included 18 sq ft (1.7 sq m) in three arch tubes.

35's career on the H&BTM was relatively short; the railroad sold it to the Susquehanna & New York in 1934 as their 119. After eight years on that road, the 119 moved on to the Clarion River of Hallton, Pa. Nine years later, the CRRR scrapped the 119 in 1951.

The 36 served H&BTM considerably longer, only being sold to the Canada & Gulf Terminal in 1948. After six more years of service, the engine was scrapped in 1954.
