Robot Trains

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 Dukes lie is revealed! To fulfill his evil scheme, Duke forcefully tries to take over the Train World. But with his last ounce of strength, Kay stops Duke using his lethal combat technique, Maximum Overdrive.

As the power of the Train World becomes weaker, viruses spring up and begin to infect the inhabitants. If infected, the trains lose control of their engines and run until they completely exhaust their energy. While Selly searches for the vaccine, Kay and Duck enter the infected zone, Area D. The virus has already spread throughout the region, putting trains in danger.

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. With everyone cheering for him, Kay opens the tunnel gate that leads to the Mountain Area, but his attempt is hindered by a fiercely cold wind from the tunnel that freezes the Fountain Plaza completely.

When the avalanche starts to fall, Alf, Jeffrey, Selly and Duck quickly search for ways to protect the Mountain Area. Kay regains consciousness and helps Alf trying to stop the falling rocks, while the others build barriers. Alf still resents Kay for putting his friends in danger, and the two keep on arguing on duty. After watching Kay eagerly trying to save the Mountain Area,

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. While helping Kay train, Selly notices that Janne likes Kay and that she wants to help him. Selly assigns Kays training to Janne while she goes to install a weather station with Alf.

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. When Kay asks him for the reason, Alf speaks his mind. Alf believes that he could have saved Kay and completed constructing the Intercontinental Railroad if he had gone with Kay instead of Duke.

Duke in the virtual space is unimaginably strong. After losing connection with Selly, Kay, Alf and Duck are completely exhausted, fighting against Duke. On the other end, Selly is puzzled that the program has gone out of control. While Alf wakes up from his dream, Kay and Duck are still trapped in the virtual space with the formidable foe.

Kay and Alf tie with eleven cargos each, which they have received from helping other trains. With Kays Base as the last section of the race, Kay and Alf fight for each others cargos but end up giving all their cargos to Duck who was strolling at the bottom of the hill when the law of inertia works in Ducks favor.

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, all their efforts are useless against the powerful enemy. But when Kay and his friends refuse to give up, Duke starts up his engine to suck in all the energy from the Fountain Plaza and causes a blackout.

As the tunnel to Area V reopens, Victor is back. Victor visits the gatekeepers of each area who are his old students. Watching everyone welcoming Victor, Kay realizes that Victor is very much respected around the Train World and feels sad that he doesnt have any memory of Victor. After meeting everyone, Victor takes Kay to meet Stella, the fortune teller.

Kay and his friends realize that Duke has acted strangely because of a virus. To treat Duke, Kay and the gang must log into Dukes system and remove the mutant virus themselves. With the help of Selly, Kay, Alf, Duck and Victor enter Dukes system.

Duke finally comes back to the Fountain Plaza after his recovery, but everyone is still scared of him. Kay asks Duke to go training with him, but it is actually Kays scheme to help Duke earn trust back from the other trains. Up on the mountain, Kay and Duke pick up things that the others might like, but the other trains still cant believe Dukes good intentions.

Kay arrives at the Central, but the atmosphere is somewhat different than before. His friends act weird and seem to be afraid of him. Kay hears from Duck of what he had least expected. In this world, Kay is a betrayer who interrupted the opening of the tunnels and shut down Dukes engine. In a nutshell, it becomes clear that Kay had arrived in a whole different Train World.

Everyone safely makes it to Victors Base. There, Selly connects Victors engine with Kays while repairing Victor. Meanwhile, Duck is skating on a frozen lake when suddenly, the ice on the lake melts and all the water evaporates! Alf and Duke discover what has caused the situation and head out to find the source.

Dukes duplicates show up in the Fountain Plaza. It turns out the virus has duplicated Duke while it was invading Dukes system. Victor, Alf, Duck and Selly fight against the duplicates, and Kay and Jeffrey join their effort when they get back. Meanwhile, Duke, locked-up in the cell, senses that something has gone wrong.

All the trains evacuate to Area V, and the Robot Trains block the tunnel that connects to the Fountain Plaza. But Dukes duplicates penetrate and come through the tunnel, endangering everyone in Area V. Then Duke arrives to Area V just in time. It turns out Becky has unlocked Duke while everyone evacuated. Only thing that can stop Dukes duplicates is the energy coming from the Alpha Train.
