Builder info from B.Rumary, 25 Kingscombe, Gurney Slade, Radstock, BA3 4TH, ENGLAND and Jeremy Lambert as supplied by Allen Stanley in March 2004. Works number was 2421 in March 1894.
The railroad name changed to North Shore, then Northwestern Pacific, but the number always remained 16.
Apparently based on the design shown in Locobase 8167, this engine had a quite-different firebox and tube arrangement. In addition to disposing nine fewer tubes, the locomotive apparently had some arch tubes as the grate area was smaller and the firebox heating surface area was substantially larger. Narrow firebox measured 7 ft (2.134 m) long by 2 ft (0.61 m) wide. Its cab was topped by a slender box that would serve as a clerestory if it had windows.
As with the earlier engines, the 16 served the NPC, the North Shore, and the Northwestern Pacific in succession. It was sold for scrap on 17 October 1934.
