Special thanks to Barry Maxfield for the pictures and information on this line.
Shows the rail line toward the end of track, near MP 2.75.
The line was originally built by Denver, Rio Grande, & Western as the Park City Branch, extending through Temple, Forest Dale, Sugar House, Alexander, Cement Quarry, Dale, Barclay, Roa, Altus, through Altus Tunnel, Gogorza, Kimball, Snyderville, and into Park City, where the line served the mines and mills in the area. DRG&W was in intense competition with UP in Park City, but abandoned the line to Park City in 1947. At that time, the line was apparently cut back to the remnant that was abandoned in 2005.

Shows the condition of the line looking west from the Granite Furniture Warehouse.
