FMCSA requests public comment on Mainline Services, LLC's (Mainline) application for an exemption from certain provisions in the hours-of-service (HOS) regulations. The applicant seeks the exemption for its employees who transport equipment used to clear derailed or disabled trains or debris blocking tracks or railroad rights-of-way when they are responding to unplanned events that affect interstate commerce, service, or the safety of railway operations, including passenger rail operations, and that occur outside of or extend beyond the employee's normal shift. FMCSA is required by statute to publish a notice explaining each exemption request. This notice does not indicate what decision FMCSA will ultimately reach on the request. After reviewing the application, safety analyses, and public comments submitted, FMCSA will grant or deny the exemption.
