Tender Booster

[nw-mailing-list at nwhs.org]

While looking through the collection of photos in the Virginia Tech collection, I ran across two photos of a N&W Y-3 that had a significant amount of piping between the locomotive and tender.  One photo has the notation "Application of Bethlehem Tender Booster 5-19-27."  I have never heard of a tender booster and wonder if someone can provide an explanation.

The photos are found at http://spec.lib.vt.edu/imagebase/norfolksouthern/full/ns966.jpeg
and ....ns965.
