This view would also been a real treat to have as a real photo in color, but alas, Short Line is long gone and never coming back... This view is showcasing the way the Short Line is climbing uphill, showing four levels of tracks with trains painted in on the first and third level.
It also have a piece of the High Drive road in Cheyenne Canon about 1/4 up from lower right hand corner. I think it is the St. Peter's Dome one see about 1/4 down from upper right hand corner.
The 4th level seen at left of the top I think is St. Peter's Dome, or a little to the right and up from the highest drawn in train, is the part of the grade that comes out of Tunnel No. 8, often seen in views marked as Approaching Duffields.
