Data from "Small Shunting Engine for the Caldon Lime Quarries", The Locomotive Magazine, Volume VI [6], (June 1901), p. 107.
As indicated by the LM article's title, this was a small, efficient saddle tanker for quarry work. The tramway linked the quarry to the Trent-Mersey Canal. The tramway opened in 1847 and closed in 1934.
