Data from "Narrow-Gauge Tank Engines for India", Locomotive Magazine, Volume XXVI [26] (15 April 1920), p. 72.
One of several of McLeod's Light Railways (MLR), the BK operated in West Bengal near Calcutta when opened on 1 December 1915. Total length of the railway was 53 km (33 miles). Locobase doesn't know how many were in this order.
