Faster Trains Near Curbs: Quieter Zones Get Speed Boost

Published Date: 4/28/2026

Rule

Summary

Starting May 28, 2026, trains can safely allow cars to drive up to 45 mph near special curbs called non-traversable curbs in quiet zones. This change helps drivers go a bit faster without extra train horn noise, making travel smoother and safer. It mainly affects communities with these curbs and could save time and money by reducing unnecessary slowdowns.

Analyzed Economic Effects

3 provisions identified: 3 benefits, 0 costs, 0 mixed.

Allow 45 mph Near Non‑Traversable Curbs

You can drive up to 45 miles per hour where non‑traversable curbs are present in quiet zones starting May 28, 2026. The rule defines these curbs as at least six inches high and permits highway speeds that do not exceed 45 mph, which the FRA says can reduce slowdowns and horn use in affected communities.

Codifies Five Waivers, Ends Repetitive Waivers

The rule codifies five longstanding FRA waivers and means regulated parties will no longer need to submit periodic, repetitive waiver requests related to the non‑traversable curb definition. FRA states this change will produce cost savings for impacted parties by eliminating those waiver filings, effective May 28, 2026.

FRA Recommends Engineering Controls for 45 mph Curbs

The rule adds a recommendation in appendix A that use of non‑traversable curbs at speeds up to 45 mph should incorporate appropriate engineering controls, such as those recommended by organizations like AASHTO. FRA declined to incorporate AASHTO by reference but explicitly recommends these design elements to support safety where higher speeds are used.
