Use of Track Strength Data in the Determination of Future Crosstie Requirements

摘要

The new generation of objective track strength measurement systems, which measure the lateral deformation (and associated strength) of the tie/fastener systems in track, is currently being used by a number of railroads, to measure the track strength from a safety point of view. As such, it serves as an effective means of locating weak spots, particularly clusters of poor or inadequate ties, in track. However, this new generation of data also offers the potential for developing maintenance parameters for ties and fasteners, based on the same level of objective information.
