Chesapeake & Ohio 0-4-4 "Forney" Locomotives of the USA


Class Details by Steve Llanso of Sweat House Media

Class B-1 (Locobase 11151)

Data from Schenectady Locomotive Works, Illustrated Catalogue of Simple and Compound Locomotives (Philadelphia: J B Lippincott, 1897), pp. 194-195. Works numbers were 2719-2720 in 1889.

Rolling on an unusual wheel arrangement on any railroad, this pair of Forneys held on to their original numbers until the second decade of the 20th Century. Then they were renumbered three times in two years.

1003 was sold in March 1912 to J T Gardner. 1004 was renumbered three more times in 1912-1913 to 1304, 44, and 48. As the latter number, the 48 was sent to the scrapper in November 1913.
