Data from "Details of Locomotives at the World's Columbian Exposition - Third Article", Railroad Gazette, Volume 25 (24 November 1893), pp. 848-849 and 851. (Thanks to Chris Hohl for his 13 January 2020 email and well-drafted spreadsheet, the latter noting the absence of this locomotive from Locobase and providing detailed data and source information.) Works number was 1429 in January 1893.
