The TV series left a specific mystery dangling intentionally, this movie comes back to close it. For a show built on the premise of AI-piloted trains saving the world, the movie finally answers what the Train Base was really hiding. If you watched the series expecting answers and got cliffhangers instead, this is the payoff that justifies the wait.

In 2100, high-speed rail has moved beyond the ground with the Laser Rail, and the Train Base turns trains from around the world into robot-bodied machines with artificial intelligence. These Train Heroes train hard and are sometimes sent to help with disaster rescue and relief. This theatrical action film follows the television series and brings to light a mystery that the series never answered.
