Chesterfield & Lancaster 4-6-0 "Ten-Wheeler" Locomotives in the USA

Class Details by Steve Llanso of Sweat House Media

Class 903 (Locobase 12969)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 29, p. 63. Works number was 28000 in April 1906.

Exactly this design of Ten-wheeler served with several other small southern American roads. Note that this locomotive had a nice round builder's number.

The C & L operated a 35.3-mile main line between Cheraw, SC and Crowburk. A meager supply of money meant that the two-county railroad would only ever operate in Chesterfield County because construction funding ran out at Crowburk.

60% of the ownership value would be picked up by the Seaboard Air Line in 1913 and the rest 10 years later. The line would be abandoned in 1941.
