I appreciate your comment, but I am not going to do the two volumes until I am satisfied with my research. I am doing this project for the RR Museum and will not get a dime for it. In fact, it costs me $100 a week in care for my wife and gas every week when I go to do my research. I started this project as an outgrowth of the OA-OZ book I did years ago. I was curious how this stuff was used. After a while I decided that it had to include the RGS as they were so linked to the D&RGW. About ten years ago, Jack Thode talked me into including the standard gauge which required research on operations and equipment in Utah. I enjoy doing the research and am in no hurry to finish. Hopefully it will all be worth it.
