Hayato Hayasugi, the train-loving son of a train museum curator, accidentally stumbles into his dad's secret research lab one day. Inside he finds the E5 bullet train. As soon as he enters, he hears an announcement that a mysterious enemy, the Bachigami, is attacking the city of New Saitama. Luckily, with the touch of his father's Shinca card, the bullet train he's in transforms into a mighty robot — the Shinkalion E5 Hayabusa. Hayato and other children will serve as conductors to pilot the Shinkalion. The children must work together with the adults of the "Shinkansen Ultra Evolution Institute" (SUEI) to defeat a monster that looks like a jet black bullet train.

A little bit in the future, the government has established a brand new organization with the purpose of rescuing lives to respond to the increasingly complicated and varied types of disasters, accidents and crimes that go beyond human comprehension. It is called the "Mobile Emergency Police DRIVE HEAD" force combining specialized police, firefighting and rescue skills. "DRIVE HEAD" is an advanced mobile device that transforms in form factor from car to humanoid walker vehicle. The drivers are high-aptitude, grade school students such as Go Kurumada who collaborate with mobile emergency police adults and rush to crisis situations to secure public safety and preserve the peace for all!
