Thanks Dave and Hank, I pulled my copy out of the book shelve and started thumbing through it, page 126 has and interesting quote stating that 460 was removed from the 4th Division to the 3rd Division in 1935, 464 picked up the duties of fighting the snow off of Cumbres, in the picture on that page 464 has the wedge plow on it sitting in front of the Chama Roundhouse with 4 doors of the roundhouse seen in the picture. R.V. Nixons photo is on Page 99 of this same book, Nice, just really nice. So it looks like 463 was the Wedge plow for the Durango and Silverton Section with pages 123 and 124 showing it in Durango and just returning from Durango.
Thanks again for the advice, half of my problem is that I have the books I just don't know were to start sometimes.
Still a Student,
Dave
