Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 45, p. 22. (Thanks to Chris Hohl for his 9 May 2015 email and spreadsheet pointing out the lack of an entry for the number 6 and for supplying the detail.) Works number was 38085 in August 1912.
Rail weights on this North Carolina logging railroad were a very light 25-30 lb/yard (12.5-15 kg/metre) rail.
