About Train Speed Limits

From Factorio Mod Portal

Limit train speeds in specific signal blocks with configurable settings.

Train Speed Limits

The Train Speed Limits mod lets you assign a maximum speed (in km/h) to train signals, ensuring player safety around intersections and train stations.

🛠️ Features

  • ✅ Direct Integration:

It can be directly integrated into any existing world without problems. This is the same for removing the mod.

  • 🚦 Signal-Based Limits:

Speed limits need to be configured in a train signal. When a train drives past it, it will be limited to the configured speed.

  • ⏩ Continuous Limits:

Trains will maintain their speed limit until it drives past another applied signal with a speed limit or cleared with 'Unrestricted'.

  • 📉 Train Braking:

The train will start to brake after the locomotive drove past the speed limit signal. Braking is gradual like the unmodded game.

  • 🔄 Copy/Paste Compatible:

Use Shift + Right-click and Shift + Left-click to copy-paste speed settings between signals (just like vanilla).

  • 🤖 Automatic Only:

Only trains with drive mode Automatic are affected by speed limits. Manually controlled trains will ignore these limits.

❓ How It Works

  1. Place a rail signal.
  2. Click on the signal and open the GUI.
  3. Set a speed limit (in km/h) and apply it via the checkbox.
  4. Any train passing that signal while on automatic mode will adjust its speed.
  5. The limit persists across blocks until overwritten or unrestricted.

😎 Use Cases

You might be wondering, why do I need to slow down trains? Well, how many times have you been hit by a train? Probably a lot of times if you've played Factorio a lot. 😄

Most of these "accidents" happen close to intersections, train stations and mining outposts. They are the perfect places for a speed limit!

⚠️ Compatibility & Known Limitations

  • Works with vanilla and has been tested with the most popular mods.
  • Mods which affect train speed behaviour (including "fast trains") could experience small issues.
  • Initial spawn/movement may ignore speed limits until reaching the first signal with a speed limit.
  • Try to limit placing signals with speed limits in corners/turns and close to intersections. This should normally work but there are certain cases the train doesn't detect the signal.
