Notice of Safety Advisory.
Summary
FRA is issuing Safety Advisory 2012-04 to remind track owners, railroads, and their track inspectors of the importance of complying with the applicable rail management programs and engineering procedures that address rail with severe rail head wear and rolling contact fatigue (RCF) conditions. FRA is issuing this notice in response to a July 11, 2012, derailment in Ohio that a preliminary investigation indicates was likely caused by the failure of multiple defects involving detail fractures in rail exhibiting significant vertical head loss (rail head wear) and gage-side-oriented RCF. This notice contains recommendations to track owners to ensure that their employees and other entities performing track inspections comply with the requirements of the applicable engineering procedures that address critical rail head wear, particularly if the track under inspection exhibits significant RCF or a sudden increase in localized rail failure.
