In all the world this is the locomotive I would most like to see run again. Come on home 2156!

I have always felt the same way with steam engines lots of knobs and handles, but no labels!

If you study or work steam locomotives, you get the gist. The left side is the firemen's and he is concerned with the fire and water. The V formation on the bottom are the stoker jets. The upper left valve under the gauges with the wire extension has got to be the stoker engine. The feedwater heater and the stoker booster would be in the mess of valves in between. Those two upright handles on that stand next to the fire door are new to me, are they the ejectors? The top handles are off the steam manifold to power various sub machines like the stoker, the dynamo, maybe passenger steam heat and a booster. The right controls obviously would be the engineers throttle, the reverser, the two brakes, the bell, the sanders, cylinder cocks, whistle, injector, lights, and above left of the steam gauge would be two of the tri-cocks off the water column. I like how the N&W had a indicator shaft coming out of some of the valve handles. In the chaos that is a cab, knowing where the valve is set is a big help I would think. I would guess that the big valve handle with the shaft coming off the manifold is the Y-6's famed high pressure to the low pressure cylinder. When that high pressure steam was used, the Y-6's, including the 2156, developed their phenomenal 166,000 pounds of tractive effort while weighing 100,000 lbs less then an Allegheny of a Big Boy. All of this comes from a guy who knows only a little and that is dangerous!
