It's been nicely built, quality of machining is good; the superheated combustion chamber boiler has been nicely made with neat flanging and good solder penetration.\u003cbr\u003e   \u003cbr\u003e   \u003c\/div\u003e  \u003cdiv\u003e \u003c\/div\u003e  \u003cdiv\u003eScaled up from LBSC's 3 1\/2 inch gauge design, it has some interesting features including vacuum brakes for train and locomotive, with a substantial brake cylinder and reservoir neatly hidden away behind the centre frame stretcher - vacuum is piped to both ends of the locomotive and tender as per full-size practice.\u003cbr\u003e   \u003cbr\u003e   \u003c\/div\u003e  \u003cdiv\u003e \u003c\/div\u003e  \u003cdiv\u003eThe boiler has been ultrasonic checked for plate thickness, followed by a twice working pressure hydraulic test maintained for 30 minutes and is warrantied as sound.\u003cbr\u003e   \u003cbr\u003e   \u003c\/div\u003e  \u003cdiv\u003e \u003c\/div\u003e  \u003cdiv\u003eThere will be a variety of jobs required to commission for steaming: given the engine has never been steamed in the past, we'd expect packing of glands, replacement of water gauge seals, servicing pumps etc.\u003cbr\u003e   \u003cbr\u003e   \u003c\/div\u003e  \u003cdiv\u003e \u003c\/div\u003e  \u003cdiv\u003eThe engine runs on air, the offside coupling rod boss just touching the   lower guide bar which needs a minor amount of relieving to clear.
