The Rail Changer is the transformation device of the core Railmen.
While the Railmen were able to use the Rail Changer in the simulation, they were unable to do so once they were out. The Rail Changers were eventually recreated to be used in the real world, thanks to the reverse engineering of the Rail X changer.
To transform, a Railman first presses the Change button on the Control Panel. Next, he or she mounts the Rail Changer into the Changer Brace, setting it to Fight Mode, followed by activating a Railman Pass. Then, the Railman calls out Full-speed Transformation! (全速変身 Zensoku Henshin), before scanning the Railman Pass into the Pass Reader. This prompts the Rail Suit to form around the Railman, completing the transformation.
To perform an attack, known as a Next Stop attack, the Railman presses the Attack button on the Control Panel once, before calling out the name of the attack he or she wishes to perform. Finally, the Railman swipes his or her Railman Pass to initiate the attack.
The procedure of performing a finisher, known as a Last Stop attack, is similar as above, but the Railman has to press the Attack twice instead of once.
To summon his or her personal Railman Weapon, the Railman presses the Summon button on the Control Panel. Next, he or she activates his or her personal Railman Pass to then swipe it over the Pass Reader.
To summon the Railer Machines, the Railman first presses the Summon button on the Control Panel. Next, he or she activates the Whistle Railman Pass, to then swipe it over the Pass Reader.
