    About

    Underwater Rails adds rail variants that let minecart tracks run underwater. It includes basic rails, which can be placed underwater but do not prevent drowning, and advanced rails, which protect a player from drowning while riding a minecart on them and, in the Forge version, disable underwater fog. Both types are available as standard, powered, detector, and activator rails; in versions where vanilla rails can already be placed underwater, the mod provides only the advanced underwater rail.

    Not checked yet

    It has no file for a recent Minecraft version. This is about its files for Minecraft 1.12.2 to 1.18.1.

    Its author does not let other sites download its files from CurseForge, so we cannot check them.

    Why we show this: a mod runs on your computer like any program, so harmful code in it can take your accounts or files. Our checks look for known signs of harm. They cannot prove that a file is harmless. In the grade: malware means no grade, and a Warning in a latest file for a recent Minecraft version lowers it.

    How we checked · Not checked yet
    • FilesWe download the files from Modrinth or CurseForge and look at what is inside them and what their code can do, without running them. Fixed rules tell what is harmful.
      4 latest files: the newest file for each Minecraft version and loader. None is for a recent Minecraft version, so the answer above is about all of them. Recent versions: those released in the last 2 years, plus 1.20.1 and 1.21.1, among the most played in modpacks. See each file in Releases

    Privacy

    We have not read its code yet

    It has no file for a recent Minecraft version. This is about its files for Minecraft 1.12.2 to 1.18.1.

    What it sends is not known yet.

    Why we show this: a mod can send things about you over the internet, like your player name or your login. Contacting an address to check for updates or download files sends nothing about you. Not in the grade: sending data can be normal for what a mod does.

    How we checked · Code not read yet
    • Files readWe read the code without running it. We list each web address the code contacts while you play, and what it sends. Code that is never used is left out.

    AI

    No sign so far that AI was used to make it

    We looked for AI tools in its texts and found none.

    We have not read its files, images, sounds and code history yet.

    AI in the game: not checked yet

    We have not read its code for AI yet.

    Why we show this: some players and servers avoid projects made with AI, and AI in the game can send what you write to an online service. Not in the grade: using AI does not tell whether a project works well or is kept up to date.
