Performance of Elastic Fasteners on an 8-Degree Curve in Revenue Service

Abstract

A test of elastic rail fastening systems was conducted on an 8-degree curve in the Norfolk Southern (NS) Mega Site as part of the Revenue Service Test Program, which is jointly sponsored by the Association of American Railroads and the Federal Railroad Administration. The two elastic fastener types, from two manufacturers, were subjected to 260 MGT of mostly HAL traffic since their installation in June 2005. In January 2010, NS decided to remove all the elastic fasteners from track, effectively terminating the test.
