FRA Updates Brake Checks with Waivers Baked In
Published Date: 8/31/2026
Rule
Summary
This rule amends mechanical equipment safety standards related to brake inspections for passenger and freight rail equipment and incorporates longstanding waivers for locomotive brake system maintenance and inspection requirements. The amendments are consistent with the mandates of the Infrastructure Investment and Jobs Act (IIJA), which require FRA to review and analyze certain longstanding waivers to determine whether incorporating the waivers into FRA's regulations is justified, and Executive Order 14219, Ensuring Lawful Governance and Implementing the President's "Department of Government Efficiency" Deregulatory Initiative.
Analyzed Economic Effects
4 provisions identified: 4 benefits, 0 costs, 0 mixed.
Codifies Waivers — Saves Railroads Time
The rule makes longstanding FRA waivers permanent so railroads no longer must repeatedly apply for those waivers and five-year extensions. FRA says this will save railroads and the Federal Government time and compliance costs by eliminating repeated waiver petitions and extension requests.
AFM Calibration Interval Extended for Digital Units
Analog air flow meter (AFM) indicators must be verified at intervals not to exceed 92 days, while digital AFM indicators with auto-calibrating functionality may be verified at intervals not to exceed 184 days. Any AFM found out of tolerance must be calibrated and calibrations must be done at temperatures of not less than 20 °F.
Longer Brake Maintenance Intervals for Many Systems
The rule sets specific maximum intervals for periodic brake maintenance: e.g., level one maintenance every 368 days; for many locomotives level two at up to 368 days and level three up to 736 days; and for specified brake systems periodic intervals up to 1,104; 1,472; 1,840; 2,944; 3,128; and 3,680 days depending on system type. Similar interval tables are adopted for DMU/MU locomotives, passenger coaches, and cab cars.
EAB Systems Must Pass Self-Tests During Inspections
For locomotives and passenger equipment equipped with an electronic air brake (EAB) system, the rule requires a self-test of the operational health of the brake system to be performed and successfully passed as part of the periodic mechanical inspection.

2026-17787, Repealing Special Approval Requirement for Freight Cars More Than 50 Years Old
Starting September 30, 2026, railroads no longer need special approval to use freight cars over 50 years old or with certain older parts. Instead, they just have to notify the Federal Railroad Administration and provide some info, making things faster and easier. This change helps railroads save time and cut red tape without extra costs.
2026-17783, Regulatory Relief From Locomotive Horn Sounding Pattern at Public Highway-Rail Grade Crossings
This final rule amends safety standards related to use of the locomotive horn to provide regulatory relief from the required pattern of sounding the locomotive horn in two long blasts, one short blast, and one long blast for locomotive engineers operating trains, locomotive consists, or individual locomotives that have stopped in close proximity to a public highway-rail grade crossing. This final rule allows locomotive engineers to vary the locomotive horn sounding pattern to one single blast of the horn as they enter the nearby public highway-rail grade crossing.
2026-17792, Permitting Use of Computer-Based, Three-Dimensional Simulation for Periodic Refresher Training on Brake Systems
This rule permits railroads to use a simulation that is instructor-led, computer-based, and three-dimensional (3D) to satisfy the hands-on portion of periodic refresher training under FRA's brake system training requirements, consistent with waivers FRA has granted to date. This computer-based 3D simulation training can provide employees with randomized scenarios that may not be readily available for hands-on training and facilitate real-time feedback on performance of duties.
2026-17790, Retiring Form FRA F 6180.107 and Form FRA F 6180.150
This rule retires Form FRA F 6180.107, "Alternative Record for Illnesses Claimed to be Work-Related" (Form 6180.107), and Form FRA F 6180.150, "Highway User Injury Inquiry Form" (Form 6180.150). This rule also changes the record retention period required under FRA's accident reporting regulations and makes other technical corrections.
2026-17791, Miscellaneous Amendments to FRA's Accident Reporting Regulations
This rule makes miscellaneous amendments to FRA's accident reporting regulations. Specifically, these amendments promote submitting documents to FRA electronically, eliminate redundant regulations, and allow railroads with additional time to complete certain forms.
2026-17786, Enhancing Railroad Discretion in Sounding Locomotive Horns at Passenger Stations
This final rule amends safety standards related to the use of the locomotive horn to clarify that no Federal regulation requires a railroad to sound a locomotive horn because of the presence of a passenger station. The final rule clarifies that a railroad has discretion to determine policies for sounding a locomotive horn at a passenger station through railroad operating rules. The final rule also provides that if a railroad decides to sound a locomotive horn at a passenger station, the minimum sound level requirements in FRA's Railroad Locomotive Safety Standards do not apply to the sound produced by the horn.
