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||Qty.||Road Numbers||From Other RR||Year Acquired||Year Built||Builder||Notes|
|O-1||7||2000-2006||1918||Baldwin||Numbers 2000-2003 and 2005 were sold to the C&O in 1945 and became C&O numbers 2000-2003 and 2005. They were scrapped in 1951. Numbers 2004 and 2006 was sold to the Central of Georgia in 1945 and became Central of Georgia numbers 711-712. They were scrapped by1950.|
|O-2||2||4000-4001||Wabash||1942||1917||ALCO||Bought from the Wabash in 1942. Ex Wabash numbers 2513(C&EI #4000) and 2509 (C&EI #4001). Numbers 4000 and 4001 Sold to the C&O in 1945 and became C&O numbers 4000 and 4001. These two locomotives were scrapped in 1949.|
|O-2||5||2007-2011||1919||ALCO||USRA allocated .Santa Fe-Heavy. locomotives. They were refused and the USRA transferred them to the PRR.|
The specs predicted an adhesion weight of 300,000 lb (136,078 kg) and 377,300 lb (171,141 kg) in engine weight and the boiler pressure was to be set at 185 psi. The combination would generate a 4.18 factor of adhesion. The diagrams all show, however, that the engines weighed about five tons less and the boilers were pressed to 200 psi. This was still manageable for a freight locomotive.
Piston valves measured 13" (331 mm) in diameter. Firebox heating surface area included 73 sq ft (6.78 sq m) from the combustion chamber and 38 sq ft (3.53 sq m) in the arch tubes.
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). A larger tender weighed 305,000 lb (138,346 kg) loaded and carried 16,000 US gallons of water (60,560 litres) and 20 tons (18,144 kg) of coal.
The Central of Georgia bought the 2002 and 2006 on 16 January 1942 and renumbered them 711-712. Five became Chesapeake & Ohio B-2s (2000-2001, 2003-2005) when they were sold off in 1945, near the end of World War II.
