Data from "Beira Narrow Gauge Railway Locomotives," The Locomotive & Railway Carriage & Wagon Review, Vol IV (October 1899), p. 158.
See Locobase 10127 and 10128 for the Eight-wheelers that tooled along this railway at 12 mph. These goods locomotives were rated at 10 mph.
Like the 4-4-0s, these were rendered redundant by the 1900 conversion to the 3' 6"gauge.
