Abstract
A railroad track monitoring system is described which detects changes in rail track geometry that could lead to derailments, The changes in geometry are detected via analysis of temperature and stress parameters that are collected at one or more sensors installed on the track. Methods are described which provide faster detection and reduced false alerts, thereby saving time and expense to the railroad system.
