Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 29, p 177. Works number was 29037 in September 1906.
GJLC operated 27 miles in a relatively gentle landscape in Bertie County, North Carolina, at least as far as the line's layout went. The specifications noted that grades amounted to 1%-1 1/4% and curves measured 10 degrees in radius (350 feet). This little Mogul was expected to haul 310 tons up the 1% grade.
