Abstract:

As described in our companion reports, we are developing track safety models for both rail buckling and railhead cracking. And while these two failure modes are not the most commonplace causes of train derailments according to the FRA, when derailments due to one of these causes occur, they tend to be both catastrophic and costly to the nation. It is therefore advisable to append to our models sufficient information for track engineers to be able to make timely and cost-effective decisions regarding track worthiness as it relates to these two failure modes. We, therefore, proposed to develop a national database for assessing track worthiness on the fly, similar to a procedure developed at the Texas A&M Transportation Institute for assessing small airport worthiness. This database was intended to provide track engineers with on-track information so that on-the-fly decisions could be made regarding both track buckling resistance and track resistance to catastrophic rail fracture.
