It puts two Leiji Matsumoto rail lines on the same track and dares you not to get chills. The Galaxy Express 999 goes down on a dead world, and suddenly Maetel and Tetsuro, the ten-year-old street kid with more heart than the adults around him, are cargo waiting on a rescue that may not come. The SDF's Sirius Platoon draws the job, and this is a franchise that has never pretended a uniform makes you survivable. The Herise Time Mystery is the real antagonist, a rift in the deep axis of time and space that does not care who it swallows, and the threat is that it repeats. Four episodes, no filler, all of it about people throwing themselves at a clock that already won once. If the Conductor's silhouette and a train whistle in vacuum do something to your chest, you already know why you're here.

Set in a far future where a vast railway network links the planets, this four-episode sci-fi drama OVA continues The Galaxy Railways. Strange, unexplained incidents on the trains have put the railway's service in doubt. Then headquarters receives an SOS from the Galaxy Express 999, which has crashed near Herise, a forbidden planet where the galactic tracks come to an end and which people call the planet of forgotten time. Aboard are the Conductor, Killian, Maetel and Tetsuro, a kind-hearted ten-year-old street kid. The Sirius Platoon, the railway's elite self-defense unit, is ordered to save them before the Herise Time Mystery, a rift deep in time and space, happens again.
