Section 229.207 - New locomotive crashworthiness design standards and changes to existing FRA-approved locomotive crashworthiness design standards(a)General. The following procedures govern consideration and action upon requests for FRA approval of new locomotive crashworthiness design standards and changes to existing FRA-approved locomotive crashworthiness design standards, including AAR S-580 (incorporated by reference, see § 229.205 ). Only a standards body which has adopted an FRA-approved locomotive crashworthiness design standard may initiate these procedures for FRA approval of changes to the standard.(b)Petitions for FRA approval of new locomotive crashworthiness design standards.
