All new locomotives and replacement engines must be certified to Tier 4 standards to be eligible for CMP funding.

There are very limited CMP funding opportunities for Class 1 freight railroads and such projects will be subjected to a case-by-case approval by CARB.  Class 3 freight railroads and passenger railroads are not subject to any CARB fleet regulations and are therefore eligible for CMP funding.

There are currently three types of locomotive projects that are eligible for CMP funding:

1. Locomotive replacement (the reuse and/or recycling of the baseline chassis is allowed if the baseline engine is destroyed)

2. U.S. EPA-certified engine remanufacture kit or repower

3. Head-end power (HEP) unit (apply as an off-road engine project)

Locomotive project activity must be based upon fuel consumption.

Please refer to the 2017 Carl Moyer Program guidelines for additional information regarding these project types:  https://www.arb.ca.gov/msprog/moyer/guidelines/2017gl/2017_gl_chapter_6.pdf

How to Apply:

The application period for the 2023 Carl Moyer Program is now closed. Please check back in late 2024 for updates.
