OK,
Russo scooped me on this one. I was waiting until the museum could accept credit cards, and that has been stalled for some unknown reason.
The book has just come out, and the ISBN number is not yet online.
However, it is for sale for $15 by the
Southern Forest Heritage Museum
P.O. Box 101
Long Leaf, LA 71448
or I can sell you one directly by sending me a PM here.
For the record, this is not a comprehensive history of the railroad (that is still unfinished) but it is a short history of the railroad for sale at the museum only, and all proceeds go directly to them.
They cannot take credit cards yet but if you send a check for $15 plus $2.20 for first class postage ($17.20) they will send you a copy. Or you can PM me, and send them a check marked for the book.
Here is a shot of the cover.
