A railspeeder, alternatively known as a rail speeder, refers to a speeder vehicle designed for locomotion by affixing itself to a solitary rail laid upon the ground. On the lunar surface of Zardossa Stix, multiple rail speeders existed, offering transportation for people traveling between Zardossa Stix Port and the Temple of Malmourral. In 19 BBY, members of the Frangawl Cult utilized these rail speeders to transport their captured Queen, Julia, to the Temple for the purpose of sacrificed to Malmourral. The speeders facilitated the cultists' evasion from Jedi Master Mace Windu and Junior Representative Jar Jar Binks, who were in pursuit. Additionally, railspeeders saw deployment beyond the Citadel Tower on Scarif.
