Vain Train and Loco learned of the legendary Fountain of Youth hidden away at the Los Jóvenes Dude Ranch in the American West, after spying on the Robo Rebels' vacation. They siphoned out the waters and isolated an anti-chroniton agglutination from the liquid. Loco used the substance to freeze his structure in time, making him practically invulnerable. Vain Train wanted to use the substance too, but the selfish Loco locked it up before attacking the Robo Rebels. Unfortunately for the Renegades, Bent Wing and Raizor distracted Loco while Tail Pipe and Super Couper disabled Vain Train and found a way to reverse the agglutination's effects. The Renegade rail engines were forced to flee empty-handed.
After an absence of thousands of years, Vain Train and his brother Bullet were returning to GoBotron from a deep space exploration mission with their crew. The long mission had only exacerbated the rivalry and bad feelings between the brothers. Before they could reach home, however, they were attacked by Renegades. Their ship was disabled by Space Hawks and brought aboard Roguestar. Cy-Kill noticed the tension between Bullet and Vain Train and plotted to take advantage of it. He secretly used his mind control powers to make Bullet bully Vain Train more than usual. With the stage set, Crasher stepped in and convinced Vain Train to sign on for the Renegades. Bullet and most of the rest of the crew ended up joining the Guardians, which only further separated the two brothers.
Using a modified Astro-Beam, Cy-Kill managed to transport the entire Communication Moon of GoBotron away from Guardian-controlled space. He brought Vain Train and a team of Renegades to the moon to plunder its secrets, unaware that Leader-1 was caught in the Astro-Beam effect too. Leader-1 disabled Vain Train and Cy-Kill's other five lackeys before confronting the Renegade leader himself.

He was retroactively added to GoBots continuity by Renegade Rhetoric, and given the GoBots name of "Vain Train".
- Vain Train's Cybertronian-style body in the "Cataclysm universe" is modeled on Yukikaze from The Headmasters toyline.
- The author acknowledged that Vain Train's appearance in "Going Loco" was a deliberate continuity error in celebration of the continuity errors often found in the original Challenge of the GoBots series, because he is meta in ways we are not.
