View looking South along Highway 6.
The Tintic mining branch of the Denver & Rio Grande built in 1891-92 located near Payson UT. It is 43.75 miles long and has a spur coming off of it called the Goshen Valley Railroad, built in 1919. This spur is 6.52 miles long and has a sub-spur from that which is 2.27 miles long. The mainline used to go through an old mining town called Eureka. Past the first spur, most of the rails were pulled up in the early 1970's. The first 10 or 15 miles of this spur, starting in Springville, is still used today on an irregular schedule to a limestone quarry. Thereafter, it hasn't seen rail traffic for at least 30 years.
According to the SPV Railroad Atlas, the abandoned portion extends from Elberta to Pearl, Hillside, Laguna, Canyon, Homansville, Summit, Eureka, Mammoth Crossing, Silver City, then crossing the UP and ending at Tintic Mills. The 6.52 mile spur from Pearl extended to Flora and Dividend, with a sub-spur from Flora to Burgin to Iron King. This spur and sub-spur make up what was known as the "Goshen Valley Branch" in later years. The following pictures are all of the Goshen Valley Railroad/Branch.
