FRA Finalizes Rule Allowing 3D Computer Simulation for Railroad Brake Training Refreshers

What the Rule Does

The Federal Railroad Administration (FRA) has issued a final rule amending 49 CFR part 232 to permit railroads to use instructor-led, computer-based, three-dimensional (3D) simulation to satisfy the hands-on portion of periodic refresher training under FRA's brake system training requirements. The rule is effective September 30, 2026.

The amendment targets paragraph (b)(8) of 49 CFR 232.203, which currently requires that a railroad's periodic refresher training program include both classroom and hands-on training. Under the existing regulation, observation and evaluation of actual performance of duties may already be used to meet the hands-on requirement. The final rule adds computer-based 3D simulation as an additional qualifying method alongside that existing option. The rule states that such simulation alone would not be considered sufficient for initial training, which continues to require railroads to adopt and comply with a broader training, qualification, and designation program for employees who perform brake system inspections, tests, or maintenance.

Background and Rationale

The rule is consistent with waivers FRA has already granted to railroads for the use of this type of simulation. FRA published a Notice of Proposed Rulemaking (NPRM) on July 1, 2025, proposing to allow railroads to use "three-dimensional virtual simulation" to satisfy the hands-on refresher requirement. The comment period closed on September 2, 2025, during which FRA received comments from six entities: the Association of American Railroads (AAR) and the American Short Line and Regional Railroad Association (ASLRRA), filing jointly; the Brotherhood of Locomotive Engineers and Trainmen (BLET); the Brotherhood of Railway Carmen Division (BRC) of the Transportation Communications Union; the International Association of Sheet Metal, Air, Rail, and Transportation Workers–Transportation Division (SMART-TD); and the Transportation Trades Department, AFL-CIO (TTD).

The document states that FRA is reviewing its regulatory requirements in 49 CFR parts 200 through 299 and updating requirements to reduce unnecessary burdens without compromising transportation safety, consistent with Executive Order 14192, Unleashing Prosperity Through Deregulation (90 FR 9065, Feb. 6, 2025), and Executive Order 14219, Ensuring Lawful Governance and Implementing the President's "Department of Government Efficiency" Deregulatory Initiative (90 FR 10583, Feb. 25, 2025). According to the document, 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.

Terminology Change and Scope

In moving from the NPRM to the final rule, FRA transitioned from the phrase "3D virtual simulation" to "computer-based 3D simulation." The rule explains that "virtual" may be perceived to mean only higher-fidelity immersive virtual reality simulations requiring head-mounted displays and hand controllers, potentially excluding lower-fidelity 3D simulations traditionally administered via desktop, laptop, or tablet. The term "computer-based," the rule states, is generic enough to encompass all 3D simulation types.

Industry and Labor Opposition

Generally, BLET, BRC, SMART-TD, and TTD opposed the rule as proposed. Multiple unions asserted that computer-based training cannot replace real-world, hands-on training and does not support environmental exposure to unpredictable elements such as weather or physical and sensory inputs. BLET further asserted that even if the proposal promotes consistent training, it does not assure an equivalent level of quality or educational benefit, and expressed concern that computer-based training may be rushed.

What to Watch

The rule takes effect on September 30, 2026. Railroads subject to 49 CFR part 232 will need to ensure that any use of computer-based 3D simulation for periodic brake system refresher training is instructor-led and that initial training programs continue to meet the broader qualification and designation requirements of 49 CFR 232.203.
