It is 1989. Following the destabilization of the nation of Hinomoto during the previous World War, the emergence of new technologies has facilitated its revitalization. Modern engineering has produced aircraft, gasoline engines, and geomagnetic technology—transforming transportation. Railroads have become nearly obsolete, supplanted by more efficient modes of transit. Nevertheless, a group of spirited "Raillords" seeks to restore the railroads' former glory. The Raillords, depicted as energetic and lively girls, serve as humanoid control modules for their designated railways. They convene in Ohitoyo City for the Raillord Summit, led by Suzushiro, a Raillord from Manoka Railways. Together, the group leverages its teamwork to get the railroads back on track, heralding a "new railroad age."
