Robot Trains

The Train World is having a busy period, building railroads between continents. The Intercontinental Railroad construction is to revitalize the isolated continents by installing connecting railroads.

Duke returns to the Train World and lies to everyone that Kay is lost due to an unfortunate accident. But Kay also makes it back, and Duke’s lie is revealed!

After a long rest, Kay wakes up, clueless to who or where he is. Confused, Kay leaves his base and arrives at the Fountain Plaza.

As the power of the Train World becomes weaker, viruses spring up and begin to infect the inhabitants.

A virus enters the system in Area D, and the area’s control unit malfunctions.

After Kay gets his upgrade with Experience Points from completing the Area D restoration task, he decides to reopen the railroad tunnel to the Mountain Area, where Alf is trapped.

After using all his energy while opening the tunnel to the Mountain Area, Kay collapses as he barely makes it there. Alf finds Kay in need of assistance but doesn’t step up to help him.

When the avalanche starts to fall, Alf, Jeffrey, Selly and Duck quickly search for ways to protect the Mountain Area.

Through various experiences, Kay successfully continues to receive upgrades.

Kay decides to train harder after finding out that he needs more experience points to earn higher level upgrades and starts working on his traction technique.

Kay loses control over his units because his units received upgrades after special training. He needs extra training to tame them and quickly upgrade his main system.

Kay finds out that Alf has been training hard in the early mornings. He follows Alf to the Mountain Area and sees him running too fast on the rugged mountain railroads.

Everyone needs more training to open the connecting tunnel to Area V so Selly installs a virtual simulation program to Kay, Alf and Duck’s main system.

Duke in the virtual space is unimaginably strong. After losing connection with Selly, Kay, Alf and Duck are completely exhausted, fighting against Duke.

The Train World is downgraded from Kay’s setback and the Area V, which requires a large amount of energy to be opened, remains unlocked.

Kay and Alf tie with eleven cargos each, which they have received from helping other trains.

It’s the day of the opening ceremony for Kay to finally open the tunnel to Area V.

Kay and his friends battle against Duke. Even after Alf ties Duke up, Duck shoots his water guns at him and Selly uses the G-force Nanobombs to help Kay fight Duke.

To make matters worse after all his friends have fallen, Kay’s vision sensor is broken. Jeffrey tries to fight off Duke but he’s no match for Duke.

As the tunnel to Area V reopens, Victor is back. Victor visits the gatekeepers of each area who are his old students.

Kay listens to Stella’s story about the primordial train called the Alpha Train. Stella warns Kay that soon, darkness will dawn upon them.

Kay and his friends realize that Duke has acted strangely because of a virus. To treat Duke, Kay and the gang must log into Duke’s system and remove the mutant virus themselves.

While Kay and his friends are searching for the virus inside Duke’s memories, they find Duke’s memory of the day before the opening ceremony of the Intercontinental Railroad.

Duke finally comes back to the Fountain Plaza after his recovery, but everyone is still scared of him.

Kay loses control of his engine and starts to run too fast, causing space-time to warp and twist.

Kay arrives at the Central, but the atmosphere is somewhat different than before. His friends act weird and seem to be afraid of him.

Due to the prolonged isolation period, Area V’s energy level is unstable, and the snow starts melting, causing the Ice Cave to collapse on Victor while he is investigating the cave.

Everyone safely makes it to Victor’s Base. There, Selly connects Victor’s engine with Kay’s while repairing Victor.

One morning, a train is found thrown off the track, all out energy.

Duke’s duplicates show up in the Fountain Plaza. It turns out the virus has duplicated Duke while it was invading Duke’s system.

While fighting Duke’s duplicates, Kay and his friends realize something odd. Even though the engines of the Duke’s duplicates have ceased to operate, they are still moving.

All the trains evacuate to Area V, and the Robot Trains block the tunnel that connects to the Fountain Plaza.
