Utah Department of Transportation must lead the statewide transition of commuter rail service to hybrid-electric operation, which uses overhead catenary or third-rail power plus onboard battery storage without diesel propulsion during normal operations

All existing commuter rail vehicles must be converted to or replaced with hybrid-electric vehicles before January 1, 2031, in coordination with a large public transit district

Electrification infrastructure including overhead catenary systems, substations, and related equipment must be installed and operational by January 1, 2031

Beginning July 1, 2027, large public transit districts are prohibited from placing any new commuter rail vehicle into service unless it is hybrid-electric

Implementation may occur in phases by corridor or service segment to maintain service continuity; bill takes effect May 6, 2026
