Cylinder Valve

[NW Mailing List]

I think your talking about the house valves. You open it when a locomotive is in the roundhouse
or shop to prevent steam building up in the cyls. and moving the locomotive accidentally do to leakage
 in the throttle valve

  Does anyone know what the valve located on the side of the cylinders on some locomotives is for?  The valve handle is recessed in the side of the cylinder between the valve chest and cylinder.  None of my Locomotive Cyclopedias show any info.
