The Federal Railroad Administration will permit railroads to use instructor-led, computer-based three-dimensional simulation to satisfy the hands-on portion of periodic refresher training for employees who inspect, test, or maintain brake systems, under a rule effective September 30, 2026. The change amends 49 CFR 232.203(b)(8) and makes permanent a form of relief FRA has granted case-by-case through waivers since 2012. The agency issued the final rule under Docket No. FRA-2025-0127 after a comment period that drew submissions from six industry and labor organizations. Simulation alone remains insufficient for the initial training required elsewhere in the section.
Highlights
- Instructor-led, computer-based 3D simulation may satisfy the hands-on portion of periodic brake system refresher training as of September 30, 2026.
- FRA first granted this relief to BNSF in 2012, covering the Air Brake System Virtual Training Environment (ABSVTE). BNSF reports more than 72,000 training events reaching over 25,000 employees since.
- Five Class I railroads held waivers for the practice before the rule: BNSF, Norfolk Southern, Canadian Pacific, CSX, and Canadian National.
- OMB classified the rule as a deregulatory action under Executive Order 14192, with total costs below zero.
What Changes Under 49 CFR 232.203?
Part 232 sets federal brake system safety standards for freight and other non-passenger trains and end-of-train devices. Paragraph (b)(8) requires railroads to provide periodic refresher training combining classroom and hands-on instruction, and previously allowed observation and evaluation of actual performance of duties as the only alternative route to the hands-on component.
The amended text adds a second route: a simulation that is “instructor-led, computer-based, and three-dimensional,” provided the training is documented under paragraph (e).
FRA also changed its terminology between proposal and final rule. The July 1, 2025 notice of proposed rulemaking used “three-dimensional virtual simulation.” The agency dropped “virtual” on the grounds that it could be read to cover only high-fidelity systems requiring head-mounted displays and hand controllers, excluding lower-fidelity 3D simulations delivered on desktops, laptops, and tablets.
Why FRA Added the Instructor-Led Requirement
The proposal did not explicitly require an instructor. The Brotherhood of Locomotive Engineers and Trainmen argued that computer-based training may be rushed under completion deadlines or threat of discipline, and cited a Class I railroad that generated only a final score rather than continuous feedback during refresher training.
FRA agreed that an instructor’s active involvement is essential and wrote the requirement into the final text: any 3D simulation used under paragraph (b)(8) must be led by an instructor qualified under Part 232. The agency said this aligns the rule with the waivers already granted.
Labor Groups Opposed the Rule
Four labor organizations opposed the rulemaking — BLET, the Brotherhood of Railway Carmen, SMART-TD, and the Transportation Trades Department, AFL-CIO. Their common argument was that brake system work is physical and that simulation cannot reproduce weather exposure or the sensory feedback of handling equipment.
The Carmen added two specific objections: that virtual training tends to generalize brake system features and fails to reflect differences between railroads or keep pace with updated rail car designs, and that new hires without field experience are especially exposed. TTD argued that once virtual training becomes a regulatory standard, the burden shifts to workers to justify real-world training.
FRA responded that simulation under paragraph (b)(8) must be as effective as other hands-on methods, and that where an employee fails to demonstrate the required knowledge or abilities, the agency expects the railroad to supplement with training involving in-person equipment handling. It also noted the rule is confined to refresher training.
Industry Position and Safety Data
The Association of American Railroads and the American Short Line and Regional Railroad Association filed jointly in support. According to the two groups, simulation lets railroads deliver consistent, step-by-step evaluation across varied rail car types and situations without exposing employees to injury risk in an active work setting. They noted FRA has permitted locomotive simulators for engineer certification since 1991, and that simulation training is established in aviation, marine, and trucking.
FRA said existing data show a downward trend across most critical safety metrics, including air brake-related accidents and incidents, and that its accident analysis shows improvement compared with pre-waiver statistics. AAR and ASLRRA said at least one Class I railroad recorded a reduction in certification revocations and brake testing failures after implementing simulation training.
Cost Effect
The rule eliminates the need for railroads to file waiver requests to use 3D simulation for the hands-on requirement, and removes the corresponding processing burden from FRA. All railroads gain the flexibility, not only the five that held waivers. FRA certified that the rule will not have a significant economic impact on a substantial number of small entities, and imposes no new information collection requirements.
