Only those with a great imagination can see the mystical railway known as the Rainbow Line (レインボーライン Reinbō Rain?), on which run massive trains known as Ressha (烈車?)[Note 1] are driven by five warriors. These five warriors, known as the ToQgers (トッキュウジャー Tokkyūjā?),[Note 2] protect Earth's peace from the evil forces of the Shadow Line (シャドーライン Shadō Rain?) who are using the fear and sadness of those they are abducting to establish their own railway to consume the world in darkness.
