Carl Moyer Program Funding Amounts

Carl Moyer Program funding for California's larger Class 1 freight railroads is generally limited due to the availability of Goods Movement Emission Reduction Bond Program (Proposition 1B Goods Movement Program) funding, and the South Coast and Statewide Memoranda of Understanding (MOU) with these railroads (See Table 11-1 in the 2011 Carl Moyer Program Guidelines).

Listed below are the maximum funding amounts for each eligible locomotive project type as described in the 2011 Carl Moyer Program Guidelines.
