Tender truck piping

[NW Mailing List]

A few months ago, there was some discussion about drawings that showed small diameter piping on the tender, running from the frame to trucks. 

Tonight I came across this photo of a K3 that appears to have this contraption installed. I don’t recall any firm conclusion about what their purpose was - maybe this will help?

All three branches of the piping appear to end up at the journal boxes, which suggests lubrication. My recollection of the drawing discussion was that the piping was for water, so once again I’m wondering if the intent was to take heat away from the boxes (external).
