Ressha Sentai ToQger

The Rainbow Line is a magical railway network powered by the boundless imagination that exists in our world. However, it is under threat by the evil forces of Shadow Line, who harvest darkness from the human heart to expand their own railway lines and aim to take over the world.

Standing against Shadow Line are the heroes of Rainbow Line: five childhood friends who are reunited after many years apart, but realize that they have no memories other than the time they spent together. Drawing on their imaginations to picture themselves as amazing superheroes, they transform into the ToQger and defend the world from evil.
