| These black 
                50’ steel-side, 14-panel gondolas with fi xed ends have the multi-color, circular “Rio Grande Main Line Thru the Rockies” logo, lettering 
                in white and run on
 black Barber® roller bearing trucks. The D&RGW served 
                mainly as a transcontinental bridge line between Denver, Colorado, 
                and Salt Lake City, Utah. It was a major origin of coal and mineral 
                traffi c with a motto of ‘Through the Rockies, not around them.’ 
                The Rio Grande was the epitome of mountain railroading, operating 
                the highest mainline rail line in the United States with an elevation 
                over 10,240 ft (3121 m) at Tennessee Pass.
