Class 10 (Locobase 11116)

Data from Schenectady Locomotive Works, Illustrated Catalogue of Simple and Compound Locomotives (Philadelphia: J B Lippincott, 1897), pp. 52-53.

This little wood-burner served the 36-mile-long narrow-gauge north-central railroad that would eventually form the core of Henry Flagler's Florida East Coast Railway. #10's purchase came after the railway converted from narrow- to standard gauge. This came as a result of Flagler's purchase of the J, St A & HR in 1885. was operating trains between Jacksonville & Daytona. In 1892, the J St A & HR merged with the J, St A & Indian River.
