Paper Abstract

Salient Systems, Inc. is developing the technology and the deployment strategy for wayside measurement and reporting of rail longitudinal force due to thermal expansion of CWR. A summary of this work is presented including principles of operation, test sites, and observations. Data are presented showing daily rail stress cycles, trends over weeks and months, and some unique events such as rail movement and winter snows. A perspective is given on the utility of the technology and future plans.
