Chicago & Western Indiana/Belt Railway 2-10-2 "Santafe" Locomotives in the USA


Class Details by Steve Llanso of Sweat House Media

Class C-1 (Locobase 14242)

Data from BLT RY CHG 6-1935 locomotive diagrams supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange. See also DeGolyer, Vol 55, pp. 430+. (Thanks to Chris Hohl for his extensive research into these engines, which helped Locobase develop this entry.) Works numbers were 47688, 47740-47742 in January 1918; 47866 in February.

Although in some ways these Santa Fes anticipated the USRA Heavy 2-10-2-B (Locobase 90) design in many respects (cylinder volume, valve gear, big 16" (406 mm) piston valves, e.g.) that would emerge a few months later, they had shorter combustion chambers and fewer but longer tubes. Instead, the engines reflected prewar practice in their dimensions, although the Belt chose smaller drivers for still more tractive effort created by the large-bore cylinders. The firebox heating surface area included 39 sq ft (3.62 sq m) in five arch tubes, 64 sq ft (5.95 sq m) in the combustion chamber.

Baldwin's specs note that the line had 80 lb/yard (40 kg/metre) rails and 10 degree curves. Special emphasis was given to holding the engine weight to 406,000 lb (184,159 kg) or less. Baldwin estimated adhesion weight at 336,000 lb (152,407 kg) and total engine weight at 405,000 lb (183,705). The Belt's book shows a weight on the drivers that was lower by 6 short tons and an engine weight that came in about 4 short tons less.

Like the C-2s shown in Locobase 14241, these engines were leased immediately to the Belt Railway of Chicago, which they served until they were scrapped in November 1950.


Class C-2 (Locobase 14241)

Data from Belt Railway of Chicago 6-1935 Locomotive Diagram book supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange. (Thanks to Chris Hohl for his extensive research into these engines, which helped Locobase develop this entry.) Works numbers were 60060-60064 in December 1918.

Locobase 89 shows the United States Railroad Administration design of which this batch is an example. C&WI was the parent of the Belt Railway of Chicago and leased the engines to the Belt.

Like many USRA engines, this quintet served the Belt for over thirty years. 22-24 were scrapped in April 1950; 20-21 followed in November of the same year.
