The Diamond and Caldor Railway was a common carrier Narrow gauge railway, narrow gauge railroad operating in El Dorado County, California, in the United States. The 34-mile railroad was primarily a logging railroad but also operated some passenger service. History The railroad was built by the California Door Company which was founded in 1884 in Oakland, California. The company bought 30,000 acres of wooded land in El Dorado county in 1899 as a source of timber for their plant. They initially used oxen to haul felled trees to their sawmill on the Cosumnes River. In 1901 they experimented with steam tractors for log haulage, but this was unsuccessful. In 1902, a steam-powered sawmill was constructed at Caldor, California and a planning mill 36 miles away at Diamond Springs on the Central Pacific Railroad. In late 1903, the company began construction of a narrow-gauge railroad to connect the two mills. The railroad was formally incorporated on 9 February 1904, and opened in 1905 ...

Diamond & Caldor Railway - Western Section
Diamond is a Allotropes of carbon, solid form of the element carbon with its atoms arranged in a crystal structure called diamond cubic. Diamond is tasteless, odourless, strong, brittle solid, colourless in pure form, a poor conductor of electricity, and insoluble in water. Another solid form of carbon known as graphite is the Chemical stability, chemically stable form of carbon at Standard temperature and pressure, room temperature and pressure, but diamond is metastable and converts to it at a negligible rate under those conditions. Diamond has the highest Scratch hardness, hardness and thermal conductivity of any natural material, properties that are used in major industrial applications such as cutting and polishing tools. Because the arrangement of atoms in diamond is extremely rigid, few types of impurity can contaminate it (two exceptions are boron and nitrogen). Small numbers of lattice defect, defects or impurities (about one per million of lattice atoms) can color ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
