California Report on Locomotive Emissions Reduction Options

From the AECC Newsletter:

The California Air Resources Board (CARB) has released a draft technical evaluation of options for the further reduction of locomotive and railyard emissions.

This preliminary draft discusses options such as engine replacements and the retrofitting of existing locomotives with particulate filters (DPF) or combined particulate filter and selective catalytic reduction (SCR). The technical evaluation of each option is based on the following criteria: technical feasibility, potential emissions reductions, costs, and relative cost-effectiveness. The cost of retrofitting a DPF to a locomotive is estimated by CARB at $200,000 and the cost of a DPF+SCR retrofit at $500,000.
