The "locomotives" category consists of switcher and passenger locomotives. Switch locomotives assemble and disassemble railcars, while passenger locomotives move passengers. This category also includes locomotives used at large industrial facilities to move goods and materials at fixed locations.

Locomotive mitigation measures are compiled in Table X. A summary describing the type of information provided in the table and how to use the data to quantify emission reductions from locomotives can be viewed by clicking the "Overview - Locomotives Mitigation Measure Table" link below.
