About
Open Signals adds configurable German railway signalling to Minecraft, usable with train mods or on its own. Its built-in equipment includes HV main and distant signals, Ks combination signals, Hl signals, tram signals, traffic lights, signal plates, switch levers, barriers and crossbucks. Signals can be assembled and previewed with a placer, rotated in 22.5-degree increments, and controlled manually through a GUI, by redstone, or through a signal controller or signalbox. The signalbox provides an electronic interlocking interface: players draw a track layout, link signals and redstone inputs and outputs, then set routes by selecting a start and destination signal. When a route is set, the system positions its switches and shunting signals; with route blocking enabled, it can block an occupied route and reset it after the train leaves. Redstone inputs can connect train-mod sensors to the signalbox, while outputs can trigger devices such as switches, and a pathway requester can set a route when activated by redstone. Content packs extend the available signals and related scenery, with examples including Eastern European signal systems, catenary poles, hectometer stones, and additional German signal signs.

No harmful code found
It has no file for a recent Minecraft version. This is about its files for Minecraft 1.12.2 to 1.18.2.
We checked its files and read their code, without running it.
What it can do on your computer
- Creates settings files
- The mod keeps its settings in the config folder of your game, where you can change or delete them. Only in its files for Forge 1.16.5 to 1.18.2.
- Connects to the internet
- It has code that can go online, for example to check for updates, load skins or send crash reports. Only in its files for Forge 1.12.2. See Privacy
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
- 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
- Their codeWe turn the code of the files back into readable code and follow what it does, without running it. This shows what it downloads, what it sends and where your login goes.Read without running it
- Author on ModrinthThe disclosure form on Modrinth, where the author declares that the project reads or edits things on your system outside the game. Since 13 Aug 2026, Modrinth's rules require it when this applies.Nothing declared about your system outside the game.
- Looked for, not foundWe looked for these in the file and did not find them.Folders outside the game, other programs, updating itself, the webcam or microphone, an AI service.
Privacy
We found nothing it sends
It has no file for a recent Minecraft version. This is about its files for Minecraft 1.12.2 to 1.18.2.
We read its code without running it: it contacts no web address while you play.
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
- 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.The code of all 4 files, for Minecraft 1.12.2 to 1.18.2. See each file in Releases
- Author on ModrinthThe disclosure form on Modrinth, where the author declares crash reports, usage data and advertisements. Since 13 Aug 2026, Modrinth's rules require it when a project collects data on its users or shows advertisements.Nothing declared about crash reports, usage data or advertisements.
AI
No sign so far that AI was used to make it
We looked for AI tools in its texts, files, images and sounds and found none.
We have not read its code history yet.
No sign of AI in the game
We found no AI service, AI library or AI model file in its code.
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.
How we checked
- Author on ModrinthThe disclosure form on Modrinth. Since 13 Aug 2026, Modrinth's rules require it when a substantial part of the code is AI output, when an asset is mainly AI output, or when the project or its page relies on generative AI.No AI content or AI features declared.
