The story
The Utah Railway Company was incorporated on January 24, 1912, with the name of Utah Coal Railway, shortened to Utah Railway in May of the same year. It was founded to haul coal from the company's mines to Provo, Utah, in reaction to company disappointment in the service and route of the existing Denver and Rio Grande Railroad nearby. It was known for owning the most modern equipment; when built, its large "Santa Fe" (2-10-2) and "Mallet" (2-6-6-2) steam locomotives had automatic stokers, a new invention at the time, and a convenience that drew many firemen from the D&RGW's Utah Division to the Utah Railway in 1917 when that line opened. In addition, the Utah Railway was the first to equip its air brakes with fourteen-pound tension springs instead of the standard seven-pound springs. The company was one of the earliest coal hauling railroads to employ diesel locomotives, and was early to adopt automation technologies, including the use of flashing rear end devices instead of cabooses. The Utah Railway's freight car roster consisted of fifteen flatcars and about 2,000 drop-bottom gondolas jointly owned with the San Pedro, Los Angeles & Salt Lake Railroad (later LA&SL), painted with "Utah Coal Route" lettering and UCR reporting marks. These gondolas were known to the railroad's employees as "Battleships". Parent company Mueller Industries, a manufacturer of copper products, sold the Utah Railway in 2002 to Genesee & Wyoming Inc., a railroad holding company.
