This paper deals with the resistance of the rail fastener to torsion in the plane of the track, as a factor affecting the stability of the track structure. In addition to a review of the various mathematical models used to simulate the track, this paper also reports on the results of experimental measurements of the torsional rigidity of various types of rail fasteners in use in both the United States and Western Europe, including the type of rail fastener utilized in the construction of the high speed test track at the High Speed Ground Test Center of the Department of Transportation, Federal Railroad Administration, located at Pueblo, Colorado. The results of these tests indicate a scheme for increasing the torsional rigidity of track panels. In conclusion, important considerations for the design and selection of rail fasteners for use on continuously welded rail are described.
