The Metal Train is a special speeding Train made by Dr. Mataro Madano. It was meant to be a template for the Mach Train. However, The Nouvelle Ginza turned it down. The Neo Terror convinced Madano to have revenge, causing him to adapt the identity of Dr. Mado. He made his Metal Train hijack the Mach Train on it first voyage and plan to crash it at Nouvelle Ginza's main branch. Rescue Force was dispatched to rescue Mach Train's victims and stop the Metal Train.
All of Mach Train's hostages were saved except Mikuki Maijama and Rescue Force's R1. Rescue Diver was sent in order to rescue them. Dr. Mado activated one of Metal Train's top lasers, but the remaining two were rescued.
R1's Rescue Striker and Rescue Diver combined into Jet Vehicle Mode and and began to catch up to it. But Dr. Mado has one more trick up his sleeve. It separated from the Mach Train and grabbed Jet Rescue Striker/Diver into space and transformed into its attack mode, Snake Train. After getting hits from R0's Zero Fire, the Snake Train flew downtown. Rescue Striker and Rescue Diver formed their final mode, Super Rescue Max. After a brief air battle, Super Rescue Max finished it off with its Drill Blaster. Dr. Mado survived, but he was arrested.
