Here's a caboose I caught on a CSX work train paying tribute to the B&O: CSX 904000 brings up the rear of a work train
I was at a Open House last night of the Kanawha Valley Railroad Association and saw that very caboose (in HO scale) on the end of a CSX coal train. A beautiful model, very highly detailed.
Caught this former B&O caboose yesterday evening on a BBQ Dinner Train we rode at the South Carolina Railroad Museum. Photo taken at Rion, SC, current end of the line and once the site of a large granite quarry.
That's a good looking caboose. I do think (just based on local observation) that they do get the most use on work trains.
