The Association of American Railroads (AAR) and the American Short Line Regional Rail Association (ASLRRA) are seeking modifications to the existing hours of service (HOS) regulations which they say will help the railroads improve their response to unplanned rail events such as derailments. The two groups said the existing mandate limits the railroads to respond “expeditiously” to emergency situations such as a derailment or a grade crossing incident, according to October 21 comments to the Federal Motor Carrier Safety Administration (FMCSA).
