Chicago & Eastern Illinois 2-10-2 "Santa Fe" Type Locomotives


The Chicago & Eastern Illinois Railroad bought seven "Santa Fe" type locomotives from the Baldwin Locomotive Works in 1918. These 2-10-2s were designated as Class O-1 and were given road numbers 2000 through 2006. They had 63" diameter drivers, 30" x 32" cylinders, a 200 psi boiler pressure, exerted 77,714 pounds of tractive effort and each weighed 377,300 pounds. The combined heating surface was 6,616 square feet and the piston valves were 15" in diameter.

These locomotives had a very low factor of adhesion, which is calculated by dividing the weight on the drivers by the tractive effort. With a low factor of adhesion locomotives have a tendency to slip on starting. It was probably this and the relatively slow speed that caused C&EI to sell all seven of them.

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

Class O-1 (Locobase 1418)

Data from C&EI 5 -1949 locomotive diagrams supplied in May 2005 by Allen Stanley from his extensive collection. See also DeGolyer, Vol 55, pp. 444+. Works numbers were 47949 in February 1919, 48140-48141 in March; 48284-48287 in April.

Note the relatively low factor of adhesion, suggesting that the drivers on these engines might have slipped on starting (or that sand dunes on either side of the track might have been a characteristic indication of where they started trains). Piston valves measured 13" (331 mm) in diameter. The specs predicted an adhesion weight of 300,000 lb (136,078 kg) and 377,300 lb (171,141 kg) in engine weight. The diagrams all show, however, that the engines weighed about five tons less.

Later in their careers, the C&EI reduced its small tube count by 21. This deletion lowered the tube & flue heating surface area to 4,576 sq ft (425.1 sq m).

Five became Chesapeake & Ohio B-2s (2000-2004) when they were sold off during World War II.
