From page 5...
... One of the main functions of a guard rail is to prevent flange climb derailment. Most flange climb derailments occur under the following conditions: • Tight curves or small radius switches, mostly in yards; • Low flange angle wheels; • High W/R friction coefficient, such as a new trued wheel with a rough surface; • Independent rotating wheels (IRW)
