What it does
This bill expands a federal rail infrastructure grant program to explicitly include commuter rail operators as eligible recipients for funding to develop and install regenerative braking and energy storage technologies on trains. Currently, the program covers certain rail projects but does not clearly include commuter rail systems; this amendment adds them.
Why we flagged it
The bill straightforwardly expands eligibility for federal rail infrastructure funding to include commuter rail operators pursuing energy-efficiency and regenerative technology projects. It is a routine eligibility amendment with no hidden provisions or narrow beneficiaries.
What the text implies
- Commuter rail systems may now compete for federal funding previously unavailable to them, potentially redirecting grant resources from other rail modes or projects depending on appropriations and program design.
- The amendment does not specify funding levels or appropriations, so actual benefit depends on whether Congress appropriates money to the program and how competitive the grant process becomes.

Who it affects
Commuter rail riders and the general public benefit from improved rail infrastructure, reduced energy consumption, and lower operating costs that may translate to service improvements or fare stability. The bill removes a barrier to federal funding for a public transportation technology that reduces emissions and operating costs.
Who stands to gain
- commuter rail operators
- battery and energy storage technology manufacturers
- rail equipment suppliers
Named in the bill
commuter rail operators, 49 USC § 22907, consolidated rail infrastructure and safety improvements program, section 24102 (commuter rail passenger transportation definition)
