Common place in the late th century through the mid th century, Date Nails were driven into railroad ties, utility poles, bridge timbers, and other wooden structures for record keeping purposes. Today, Date Nails are highly sought after artifacts by Railroadiana collectors. Following the Civil War , the railroad race was in full swing. In one such race, the Union Pacific and Central Pacific would compete for government favor; with the line that built the most miles being rewarded with cash and land.

In order to keep pace with this expansion, the timber needed to produce crossties was in high demand. Left untreated, wooden crossties had a life expectancy of only five to seven years. Based on the frenetic pace of laying new track and the subsequent demand of timber supplies, rail companies hatched the idea of treating the ties to increase their life expectancy. Not knowing which type of wood and treatment methods would be the most effective and economical, railroads began to experiment with varying treatments in the mid to lates.

To monitor the results of differing test sections of crossties, railroads settled on the idea of using Date Nails for record keeping purposes.

The integrity of surface artifact assemblages on historical sites can be highly variable. Some sites are virtually barren, while others are awash in refuse. This article explores the impact of rail access, wartime recycling, and differential access to consolidated refuse disposal on surface artifact assemblages found at historical sites in the American West. Sites that lacked rail access and did not participate in wartime recycling are most likely to be intact.

In addition, assemblage effects due to differential access to consolidated refuse-disposal protocols are also examined. A suite of 10 historical sites, distributed across three states and dating between and , is used to illustrate the variable effects of these three factors on surface refuse at historical sites in the West.

Formulation of recycled polyethylene terephthalate PET with pulverized recycled rubber-like material, and optimally a compatibilizing agent is described for application to railroad tie construction and other products. Desirably, the attractive formulation provides useful products from recycling of plastic PET bottles and discarded tires which greatly benefits the environment.

The formulation can be foamed during an extrusion process to reduce the density of the composite so as to be even more economically attractive. In the past, the formulated use of recycled PET in many applications would not be economical because of PET’s high material density relative to a polyethylene alternative. By way of background, solid wastes comprising garbage, combustible and noncombustible rubbish, trash, construction debris, as well as industrial, mining, and agricultural wastes, are usually disposed of in landfills.

Recycling reusable solids, particularly plastic and rubber materials, has been established as one meritorious method of solid waste reduction and environmental enhancement. The recycling industry has established a recycling code numbered from for plastic materials. The higher the number, the more difficult the material is to profitably deploy into useful post consumer applications other than by burning it for energy recovery or for disposal in landfills, which can create environmental problems.
