Data from RF Waller (Assoc M. Inst., CE), "The Magnet Tramway", in Tasmania:Report of the Secretary of Mines for 1901-1902 (Hobart, Tasmania, 1902), esp. pp. cxxiv-cxxviii).
See Locobase 8413 for an extended comment of this railway's two Mallets. Waller described this little tank as "...a good and efficient machine, and [it] does excellent work for its size. At the worst of times it pulls comfortably a gross load of 15 tons up the six-mile stretch of heavy [4%] gradient." Increasing the burden by even 3 tons overmatched the locomotive's boiler with the result, he observed, that it "...cannot make steam fast enough to keep this up for a long distance."
