A report by way of email from Roger Beckett on March 30, 2006 mentioned that there was a gravel pit that furnished ballast for UP, via a long conveyor from the pit down to a UP spur, with a locomotive being used as a facility switcher.
Further information comes from Ken Ardinger, saying that the locomotive is Twin Mountain Rock No. 57-602, painted blue and white. Its history is ex SP 5377, to SP 3855, to SP 4331, to California Northern 203, to OmniTrax Leasing (OMLX), to Kiewit Mining Group, Twin Mountain Rock (KMGX) in April 1998. According to an internet search, Twin Mountain Rock is formerly Peter Kiewet & Sons, and the Milford location is doing business as a quarry for Rinker Materials, one of the largest suppliers of crushed stone and concrete products in the U.S. The quarry is located about five miles northwest of Milford, Utah, and has been in operation since 1998.
More on Peter Kiewit and their sale to Rinker (Source1) (Source2):
"Rinker Materials Corporation, one of the largest producers of construction materials in the United States, has reached an agreement to acquire Kiewit Materials Company, the sixteenth largest aggregates producer in the United States, with operations centered in the West and Southwest." "The transaction is expected to be completed by September 30, 2002."
"Kiewit Materials' operations include 44 aggregates facilities, including eight hard rock quarries, which supplied 28 million tons of aggregate in 2001. Kiewit Materials also produced 4.7 million cubic yards of concrete in 2001 in 60 plants, and 3.4 million tons of hot-mix asphalt in 16 asphalt plants. Aggregate reserves at December 31, 2001 total over 800 million tons, with reserve life averaging over 30 years." "Approximately 80% of Kiewit Materials' operations are in Arizona..." Kiewit Materials' operations are also located near Portland, Ore., near Vallejo and Sacramento, Calif., and in Wyoming, Nebraska, Utah and New Mexico.
"Kiewit Materials was spun off from the privately-owned Peter Kiewit Sons, Inc. in September 2000." "Rinker is part of the CSR Group, the world's ninth largest heavy building materials group, with sales revenue of Australian $7 billion, operating cash flow of Australian $1.4 billion and around 16,000 employees in over 600 sites across the U.S., Australia, New Zealand and Asia." "Including the Kiewit Materials operations, Rinker will be the fifth largest aggregates producer in the U.S., supplying over 84 million tons per year, and the second largest producer of pre-mix concrete, supplying over 13 million cubic yards each year."
