Secret Weapon: D-5
Another train heist.
Autobots to the rescue
Is this a rerun?
Detailed synopsis
The Predacons mug a scientist to steal a disk that belongs to Dr. Onishi. A second scientist tries to fight off Dark Scream by tossing a fire extinguisher. A fire engine arrives, and the Predacons think it might be Optimus Prime. So Slapper licks the disk up and the three retreat.
T-AI and Optimus wonder why the Predacons are so concerned with stealing a regular disk. Prowl and Sideburn are contacted to be placed on alert.
Under the sea, the Predacons look at what's on the disk: Images of a steam engine train branded "D-5". Knowing only that the train holds some importance to the doctor, Megatron orders his goons to capture it. In the same room, Dr. Onishi mumbles something about Grampa.
Coincidentally, Koji happens to be attending a demonstration running of the D-5 train ("Grampa") with Scientist 1. Midnight Express and the Autobot brothers also attend, waiting for the Predacons to attack. The train pulls into the station where Koji and the rest of the crowd of observers are waiting. They board the locomotive and start to enjoy their trip on the anachronism. The rest of Team Bullet Train arrive to make sure the train is protected as much as possible. Oh, and Sideburn and a cow ruin Kelly's day—moo!
Sky-Byte begins the Predacons' attack on the D-5 train, attempting to invade the train's interior by sneaking down the train's smokestack, but he's quickly knocked off course by a face full of smoke. Dark Scream tries to grab onto the top of the train, but receives a face full of smoke when the train goes into a tunnel. Not entirely giving up his fight, Dark Scream gets up, but is literally railroaded by Rapid Run. Slapper gives his shot at invading the antique, but Midnight Express notices the reptile attacking Grampa and evicts the interloper. The two battle on a beach, and the Autobot clearly has the upper hand. The dastardly Gas Skunk waits ahead with a weapon, and when the train passes, he traps the two remaining train-bots in a pulse field that disturbed their fuses, but D-5, having no fuses, passes through.
The D-5 train pulls into the station successfully, and the human passengers disembark, but as soon as they're off, the Predacons commandeer the vessel. The bullet trains chase after the hijacked machine, but Sky-Byte diverts the train away from its protectors. T-AI determines that the train's new track will lead it into the water, but Midnight Express refuses to let Grampa fall into the ocean. The train derails, and Midnight Express jumps into the water after it. Underwater, Megatron tries to grab the falling choo-choo, but Midnight Express snatches the train before it literally falls into the enemy's waiting hands.
Afterwards, Koji and the Autobots understand how the endurance of the relic is a symbol of hope.

Miscellaneous trivia
- T-AI says the floppy disk is standard capacity, 1.44 Megabytes. But the correct size is 1.40 Megabytes, since the disks hold 1440 KB of data, but a Megabyte is actually 1024 KB (or (2^10) KB), not 1000 KB.
