Reduces the emissions of locomotives operating within California.

Reduces the emissions of locomotives operating within California. Switch, industrial and passenger locomotives built in 2030 or after will need to operate in zero-emissions configurations, while locomotives built in 2035 for freight line-haul operations will need to comply with the zero-emissions configurations.

The new rules also limit locomotive idling to 30 minutes except for certain circumstances, such as maintaining air brake pressure or providing heat or cooling to the locomotive cab, and they require locomotives operating in the state to register with CARB and annually report on their activity, emission levels and idling data. These two conditions would go into effect in 2024.

Effective in 2024.
