is a 26-episode science fiction anime series about flying trains in space. The anime is licensed by Funimation Production Ltd. and produced by Leiji Matsumoto. It debuted on American TV in a syndicated FUNimation Channel programming block airing on CoLours TV on Monday, June 19, 2006, but was replaced by Dragon Ball until the programming block was dropped.

Space Defense Force (SDF) Sirius Platoon Sirius Platoon, named after the star, is the main Platoon in the series. The Platoon's engine is Big One, which is based on the Union Pacific Railroad's 4-8-8-4 Big Boy locomotives, the largest steam locomotives ever built, but with many differences, like a second headlight in place of the bell and number boards, a single smokestack instead of a double one, a number board on the front of its smokebox instead of a handlebar, a second set of pipes coming out of the top cylinder heads of the rear set of cylinders, and the number "001" on its tender.

The Flame Swallow, Big One, and the Cepheus Platoon's train are equipped with Cosmo Matrix Cannon post-invasion of Alfort Armada and used only once to escape the dimensional rift at the end of the Season 2.

Bruce J. Speed

In the beginning of the season, Bruce bullies Manabu and expresses a great deal of dislike towards him. Bruce is a very commanding individual, taking charge when necessary and occasionally steps out of line, but he always steps down when Captain Bulge stops him.

Through his service to the SDF, Bruce got himself the name of "Toxic Bruce" because all his partners ended up dying in the line of duty. After the death of his second partner and Bruce got the nickname, he became a cold individual and tried his hardest to avoid getting missions with partners. Soon after this, he got a new partner, Owen, despite his argument against it. Owen was determined to get rid of the nickname "Toxic Bruce". He insisted that he was immortal, so there was no way he could die. Bruce and Owen became good friends, but on a particular mission Owen was killed beside Bruce. Because of this, Bruce blames himself for his death and deaths of all his partners and is haunted by their memory. He is often distant and cold to the members of the platoon, particularly Manabu because of his likeness to Owen, which is revealed in "Memory Gallery". After this episode, the relationship between Bruce and Manabu improves a lot, though there is still distance between them.

In Episode 18, "Life and Death", Bruce finally confronts his fear when there is a terrorist loose in the Galaxy Railways Headquarters. Bruce witnesses Manabu almost die at his side, and insists that he stay behind to protect him. Manabu, wanting to prove to Bruce that he isn't toxic, keeps following him. Manabu is at the brink of death again and Bruce saves him, breaking the curse.The Galaxy Railways Season 1: Episode 18

In Episode 22, "The Merciless Wind", Bruce is shot by an unknown attacker and dies alone outside a gas station, though it could be safely assumed that the attacker was one of the men he crossed earlier that were harassing a nurse. His funeral is held in the next episode, and it causes a great deal of sorrow for the whole platoon, especially Manabu. Manabu, being his partner, keeps Bruce's harmonica.
