Photo ID: 105319 Date Shot Photo By Saturday, July 11, 2015 Kevin Morgan Location Times Viewed East of Kobe Lake County, CO 2424 (1 Comment Posted) Subdivision Railroad Tennessee Pass (UP) Union Pacific, Rio Grande Everything about this shot screams Rio Grande! The most common ballast found along Rio Grande tracks was a black volcanic scoria, which the railroad received from a mine near Crater on the Craig Branch. The sign with the "35" on it indicates that the maximum speed for all trains is 35 miles per hour at that location. While Southern Pacific started a program to add welded rail to Tennessee Pass, the line was closed before the project could be completed. As you can see here, the main line is cleared jointed rail.
