Hocking Valley 2-10-2 "Santafe" Locomotives in the USA

The Chesapeake & Ohio Railway did not buy any new "Santa Fe" type locomotives. Instead, it acquired thirty-four of them second-hand. In 1920 through 1922, the Hocking Valley bought sixteen "Santa Fe" type locomotives from the Lehigh Valley Railroad. In 1930, the C&O merged with the Hocking Valley and shortly after sold six of these locomotives and retained ten of them for it own use. Two went to the Pere Marquette and later returned and became C&O numbers 2960 and 2961. In 1945, two 2-10-2s were bought from the C&EI, which were former Wabash locomotives. With the merger with the Pere Marquette a total of seventeen "Santa Fe" type locomotives were added to the C&O Roster.

There are no surviving C&O 2-10-2 "Santa Fe" type locomotives.

Class Details by Steve Llanso of Sweat House Media

Class F-1 / B-1 (Locobase 477)

Data from C&O Power and 1936 C& O Locomotive Diagram book supplied by Allen Stanley in May 2005 from his extensive Rail Data Exchange.

These were produced for the Lehigh Valley as R-1s 4061-4075 in November 1919 (Locobase 459), but that railroad quickly sold them to the Hocking Valley in April 1920 because their small drivers did not match the LV's faster-freight requirements.

Ten of these carried over to the C&O when the latter acquired the HV in 1930; the other six went to the Pere Marquette. At some point, tube heating surface decreased when ten tubes were deleted. As shown, the firebox heating surface includes four arch tubes comprising 29 sq ft (2.7 sq m). 14" (356 mm) piston valves had 8 1/4" maximum travel.

Cylinder horsepower calclulated to be 3,102. Elesco feedwater heater on 2952 only.

The last of these was retired in 1952.
