Showa 63 (1988), October. Hinomoto has lost most of its former railroads during the Track Closure Era. This story takes place in Ohitoyoshi, a town in the Kumamoto prefecture of the Kyushu region.
Thanks to the promotional efforts headed by the steam locomotive “8620” and its Railord, Hachiroku, the town’s once-ruined economy has been revitalized and its name is now synonymous with the renaissance of the railway.

To further raise the people’s spirits towards rebuilding the railroads, as well as to promote communication between railway companies (called “Maitetsu”) from across the nation, the town is now planning to hold the first Maitetsu Festival.
Humanoid modules that control the railways, called “Railords”, have also convened from all corners of Hinomoto with their respective masters.
The Railords, inspired by the conferences the humans hold daily and brought together by their enthusiasm, host their own “Railord Summit” with famed Railord “Suzushiro” in the center of the movement.
They gather at the railroad station café “Amairo” to share their ideas on how to add their own colors to the upcoming Maitetsu Festival.
