Subject: Informational Circular, 4-pressure Automated Single Car Air Brake Test (ASCABT) Capability Deadline Approaching
Date Issued: May 6, 2022
Date Effective: May 6, 2022
Group: Car Owner, Manufacturer, Repair Shop
Summary: AAR circular letters C-13546 & C-13607 were issued to implement an AAR Interchange Rule requirement to equip freight cars with 4-pressure ASCABT capability by 6/30/25. Rule 4, paragraph E.27 states: Control valve set not equipped with 4-pressure test capability after 6/30/25, is not allowed. This Rule was issued on 7/1/20, to notify the industry of the deadline & to provide ample time (5 years) for brake equipment to be updated. Most cars can accept a 4-Pressure access plate to provide the required capability. The application of a 4-pressure access plate kit on some equipment may be problematic due to clearance issues. The AAR is issuing this circular to provide information on available access plate configurations. Brake control valve manufacturers offer several options to facilitate the application of 4-pressure capability without modifying the car. Attachments to this Circular include catalog supplements from NYAB & Wabtec detailing the available kit options. For specific dimensions & clearance requirements, contact the valve manufacturer. Should the car design not have the necessary clearance to allow the application of a 4-pressure access plate, the handling carrier should contact the car owner for disposition. As a reminder to repair facilities, Rule 1 states an ASCABT Device(s) capable of performing a 4-pressure ASCABT will be required by 7/1/23.
