CARB Fact Sheet: Historic Locomotive Operators
CARB is developing a regulation to reduce criteria pollutants, toxic air contaminants, and greenhouse gas emissions for locomotives in-use, including locomotives operated by historic locomotive operators.
- Historic locomotives are kept in their original configuration to help interpret historical experiences and serve educational purposes transporting passengers.
- There are currently 23 operational diesel‑powered historic locomotives in California.
- Historic locomotive operators have worked with CARB staff to identify a compliance path that limits emissions, and retains reporting requirements, but allows historic locomotives to continue in their educational and interpretive roles.
- Emissions from historic locomotives are not fully documented; due to this insufficient information, emissions from historic locomotives are not included in the emissions inventory for the Proposed Regulation.
Compliance with the Proposed Regulation
- The Proposed Regulation would provide exemptions for historic locomotive operators that qualify.
- Exemptions could apply for demonstration museums, education, tourist railways and historic preservation purposes or any special one-time movements not used to haul freight for hire.
- Some provisions in the Proposed Regulation would apply to all operators, regardless of approved exemption; those provisions are:
Starting in 2024: Idling Limit
- Locomotives with automatic shutoff: locomotive would be required to shut off no more than 30 minutes after the locomotive becomes stationary. A locomotive would be permitted to exceed 30 minutes of idling for only for an exempt reason, the Proposed Regulation would list reasons for exemption.
Starting in 2024: Registration and Reporting
- Locomotives operating in the California would be required to register with CARB.
- Locomotive activity, emission levels, and idling data would be required to be reported annually.
