Ginga Tetsudou Monogatari: Wasurerareta Toki no Wakusei

Impossible landscapes are appearing across the Galaxy Railways. Before the authorities can explain them, the 999 sends a distress signal from a planet long cut off from the network.

The Sirius Platoon heads into the anomaly to recover its passengers. Meanwhile, Tetsuro carries a letter whose address only he can read. On the abandoned world, a rescue mission and an undelivered message become entangled in a disturbance of time itself.
