Their  existing 2 cylinder 4-6-0 \"King Arthur\" class was too large and heavy  for the restricted loading gauge, so the Southern's Chief Mechanical Engineer,  R.E.L.Maunsell, designed a new 4-4-0 featuring 3 cylinders to reduce wear by  hammer action on the rails. Named after the great public schools of the day, the  class went into history as the most powerful 4-4-0 ever to work on Britain's  railways.\u003c\/span\u003e    \u003cp\u003e\u003cspan lang=\"EN-US\"\u003eThis is an exceptionally well made 3 1\/2 inch gauge model  of the engine, comprising a complete running rolling chassis featuring 3  cylinders with slide valves actuated by Walshaerts valve gear. The engine turns over  very smoothly, the machining and fitting is of a very high order. The brown  discolouration to the motion in the pictures is due to preservative which will  wipe off with spirit. Steam brakes are fitted with the actuating cylinder just  in front of the rear drag beam.\u003c\/span\u003e\u003c\/p\u003e    \u003cp\u003e\u003cspan lang=\"EN-US\"\u003eThe boiler is professionally made by Chambers, silver  soldered copper construction with superheater.
