| The Pere Marquette Railway bought fifteen "Santa Fe" type locomotives from the American Locomotive Company in 1918. The locomotives were designated as Class SF and carried road numbers 1101 through 1113. They had 64" diameter drivers, 29" x 32" cylinders, a 210 psi boiler pressure and they exerted 77,059 pounds of tractive effort and each weighed 398,000 pounds. These 2-10-2s were conveyed to the C&O in 1947 and were renumbered with C&O numbers 2975 through 2989. At 324,000 pounds they were among the lightest and had a relatively small boiler and cylinder size. Also of note were the leading and trailing wheels, at 33" in diameter they were about 10 inches smaller most in use. C.W. Jernstrom photo |
