Data from table in May 1916 issue of Railway Mechanical Engineer (RME). A photo of #31 published on the Cleveland Memory website (http://www.clevelandmemory.org/SpecColl/nssbk/nss065.html, visited 18 Feb 2003) shows a stubby, big-boilered Mogul that looks like a switcher with a leading truck. But it had a superheater and big-time piston valves and valve gear.
