Battery and Regenerative Braking Act

This bill amends a federal rail safety funding provision (Section 22907 of Title 49, U.S. Code) to expand eligibility for projects developing regenerative braking and energy storage technologies. It specifically allows commuter rail operators - defined under federal law (49 U.S.C. §24102) - to apply for these grants, which were previously limited to other rail entities. The key change is adding commuter rail services as eligible applicants under existing infrastructure funding, without creating new funding streams. This directly affects commuter rail providers seeking federal support for energy-saving technology upgrades.
