Buses, Rail Cars, Ferryboats: Make it in America Act of 2010 - Eliminates certain waivers of Buy American requirements that the Secretary of Transportation (DOT) obligate federal funding for capital public transportation projects only if U.S. steel, iron, and manufactured goods are used in such projects. (Retains the current waiver of such Buy American requirements for any case where use of U.S. material will increase overall project costs by more than 25%.)
