Probably the best book with lots of pix and plans is "Silver San Juan - The
Rio Grande Southern" by Mallory Hope Ferrell, 1973, Pruett Publishing, ISBN
0-87108-057-5. But I would also highly recommend "The Rio Grande Southern
Railroad" by Josie Moore Crum, 1961, San Juan History, no ISBN. Mrs. Crum
was the wife of an RGS engineer and knew all the RR people first hand. The
book has fewer pictures and just erecting card type loco plans, but does
have county record type plats of several towns and is full of vignettes that
really give the color of operations on this line. Geezer
