Foreword

To protect the peace and safety of the Island of Sodor, combat! Steamie Transform Robot, Steamerion!

This is a crossover between Thomas & Friends and the 2018 Japanese railway-based anime series Shinkansen Henkei Robo Shinkalion, taking place 1 year after the event of Thomas and the Royal Engine. The event of Thomas & Friends: All Engines Go! won't be canon to this fanfic. Either way, enjoy!
