The Metal Train was a high speed public transit vehicle that was developed by Mataro Madano as a prototype design for the Mach Train project, but it was rejected by the Nouvelle Ginza railway company. Feeling humiliated and outraged that his design wasn't chosen, Mataro received the aid of Neo Thera in converting the train into a dangerous mecha that hijacked the newly built Mach Train for the purpose of creating a devastating explosive train wreck that would destroy the main branch of the Nouvelle Ginza company and the entire city it resided in. The mecha was destroyed by Super Rescue Max.
