Wee bits of data from "Indian Locomotives", Locomotive Magazine, Vol VI (July 1901), p. 119.
Atypical wheel arrangement that reflects British practice. H H Spalding's note accompanying the photograph in the LM story notes that it was used for mixed and goods traffic.
Data from "Thirty-Years' Development, Metre-Gage Locomotives, Indian State Railways", Railroad Age Gazette, Volume XLVII [47], No 3 (16 July 1909), p. 110; and Ahrons (1927).
Tiny tank engine delivered in batches by Dubs & Company and Nasmyth & Wilson. RAG's photograph showed the small engine set pilot-to-pilot with a metre-gauge 4-6-0 like that described in Locobase 20544.
Still in service, the older locomotive pulled passenger trains on the Rohikhund & Kumaon branch.
