Field Test Results of Soybean-Based Rail Flange Greases Using High Rail and Way Side Application Mehtods

摘要

In addition to reducing noise and track wear, there ar indications that a considerable amount of fuel savings can also be realized by using flange lubricant around of fuel used, these savings are substantial relative to the cost of application. One concern however, relates to long-term build up and/or seepage of the grease and the liability potential associated with existing or prospective regulatory actions. Using soybean oil, which is considered "readily" biodegradable according to EPA standards, improves the long-term cost potential of using flange lubricant. More importantly, soybean base oils have been proven to provide inherently higher lubricity, better adherence to metal, better tackification, higher thin-film strength, higher flash and fire points, and higher viscosity index than conventional base oils.
