Received my regular catalog from Edward R. Hamilton, Bookseller, Falls Village, CT and noted a number of Hundman books that must have been remaindered to Hamilton.
Ferrell's "Norfolk & Western - Steam's Last Stand", originally $59.99, now $24.95.
His two-volume "Slow Trains Down South" is now $19.95 each. Quite a few other Hundman titles available.

Here's a link to Hamilton's "Railroads" section http://tinyurl.com/qj7mupw
