(d) Exceptions.
(1)
A freight car or freight train equipped with a stand-alone ECP brake system shall be excepted from the requirement in § 232.103(l) referencing AAR Standard S-469-47, “Performance Specification for Freight Brakes.”
(2)
The provisions addressing the introduction of new brake system technology contained in subpart F of this part are not applicable to a freight car or freight train equipped with an ECP brake system approved by AAR in accordance with paragraph (b) of this section, conditionally or otherwise, as of the effective date of this rule.
(e) New technology.
Upon written request supported by suitable justification and submitted pursuant to the special approval procedures in § 232.17, the Associate Administrator may except from the requirements of subpart F of this part the testing of new ECP brake technology, demonstration of new ECP brake technology, or both, where testing or demonstration, or both, will be conducted pursuant to an FRA-recognized industry standard and FRA is invited to monitor the testing or demonstration, or both.
(f) Modification of standards.
The AAR or other authorized representative of the railroad industry may seek modification of the industry standards identified in or approved pursuant to paragraph (a) of this section. The request for modification will be handled and shall be submitted in accordance with the modification procedures contained in § 232.307.
