Anyone who has visited the community of Vicker on the N&W between Christiansburg and Walton is familiar with the large concrete coaling tower that straddles the tracks there at MP 295.4.
But there is a lot of infrastructure there that doesn't seem to fit with that large tower. Most of it is from the coaling facility that was there before that modern coaling tower was built. There was a ballon track that climbed to cross the tracks, with a coal trestle to transfer coal from coal cars to steam engine tenders.
Views of the structure are in the Virginia Tech imagebase. See http://spec.lib.vt.edu/imagebase/norfolksouthern/glass_plates/screen/03GP0536.jpg and http://spec.lib.vt.edu/imagebase/norfolksouthern/glass_plates/screen/03GP0464.jpg and http://spec.lib.vt.edu/imagebase/norfolksouthern/F1/NS3571.JPG.
But the trackside images don't give a good perspective of just how extensive
this facility was. This aerial view from 1937 shows that the ballon track extended
well across the road on the north side of the tracks.

Traces of the operation can still be seen today, as shown in this recent
aerial photo from the Montgomery County GIS site:

An OK view of the track layout is seen in this 1937 15-minute topo map, Blacksburg topo map.

There was a similar set-up at Dwight, Virginia, just east of Zuni. See

A good view of the track layout is seen in this 1920 (Reprinted 1944) 15-minute Ivor topo map.
