This legislation, known as the "No CIG Act," aims to eliminate federal financial support for public transportation fixed guideway capital investment projects. Its primary provision repeals Section 5309 of title 49, United States Code, which currently authorizes and governs these specific grants. By removing this section, the bill would effectively terminate the program that provides federal funding for the construction and improvement of fixed guideway transit systems, such as subways, light rail, and commuter rail. The legislation also includes necessary conforming amendments to other parts of title 49 to ensure consistency with the repeal of the grant program, thereby fully dismantling the existing framework for these investments.
