What is a Main Bus?
A main bus is a centralized conveyor belt system that acts as the backbone of your factory, transporting raw materials and intermediate products to various production facilities. Instead of having multiple supply lines for different resources, the main bus consolidates them into a single, organized structure. This approach simplifies logistics, reduces complexity, and enhances factory efficiency.
The Concept of the Main Bus
The main bus typically consists of several parallel belts, each dedicated to a specific resource. Players can design their main bus to include:
- Raw materials (like iron plates, copper plates, and coal)
- Intermediate products (like circuits, gears, and science packs)
- Finished goods (like electric engines and modules)
By following this organized methodology, players can easily access the resources they need for production, maintaining a steady workflow throughout their factories.
Designing Your Main Bus
When designing your main bus, several factors must be considered to maximize efficiency and ensure smooth operations. Here are some critical steps and tips for creating an effective main bus system:
1. Determine Which Resources to Include
Before you start building your main bus, make a list of the resources you will need for your factory. Common resources to consider include:
- Iron Plates
- Copper Plates
- Steel Plates
- Green Circuits
- Red Circuits
- Gears
- Stone Bricks
Depending on your factory’s complexity, you may also want to include other materials like modules and specialized components.
2. Choose the Number of Belts
The number of belts in your main bus should correlate with the volume of resources you plan to produce. A standard design might include:
- 2 belts for iron plates
- 2 belts for copper plates
- 1 belt for steel
- 1 belt for circuits (green and red)
As your factory grows, you can expand your bus by adding more belts to accommodate increased production needs.
3. Design the Layout
The layout of your main bus is crucial for optimizing space and ensuring easy access to all resources. Consider the following points when designing your layout:
- Width: Decide how wide you want your bus to be. Typically, a width of 4 to 6 belts is sufficient for most factories.
- Height: Ensure you leave enough vertical space for future expansions.
- Access Points: Create access points along the bus where you can draw resources for production modules.
4. Incorporate Merging and Splitting
To manage the flow of resources effectively, you’ll need to use splitters and underground belts. Splitting allows you to draw resources from the main bus without disrupting the flow, while underground belts can help you navigate obstacles and keep your layout organized.
- Use splitters to balance the load across multiple belts.
- Utilize underground belts to move resources under other belts or structures.
- Prioritize using fast transport belts for high-demand resources.
5. Plan Production Areas
As you design your main bus, consider where your production facilities will be located. Create dedicated areas for:
- Smelting (iron and copper processing)
- Assembly (manufacturing intermediate and finished products)
- Science labs (for research purposes)
Ensure that each production area has easy access to the relevant resources from the main bus.
Advantages of a Main Bus System
Implementing a main bus system comes with several advantages:
- Efficiency: A centralized system reduces transportation time and simplifies logistics.
- Scalability: As production demands grow, you can easily expand your main bus by adding more belts.
- Organization: A well-structured main bus minimizes clutter and confusion in your factory layout.
- Flexibility: Easily adapt your factory for different production needs without overhauling your entire layout.
Disadvantages of a Main Bus System
While the main bus system is highly effective, it does have some drawbacks:
- Space Consumption: A main bus can take up significant space, which may limit your factory's expansion.
- Complexity in Large Factories: In very large factories, the main bus can become unwieldy and difficult to manage.
- Resource Bottlenecks: If one belt becomes congested, it can slow down the entire factory.
Optimizing Your Main Bus
To ensure your main bus remains efficient throughout your gameplay, consider the following optimization strategies:
1. Monitor Resource Demand
Keep an eye on the production rates of your factory. If you notice certain resources are consistently depleted, consider adjusting the number of belts dedicated to those resources or improving their production rates.
2. Use Buffer Chests
Incorporating buffer chests at the end of your resource belts can help manage fluctuations in demand. This allows you to store excess resources temporarily, reducing the chances of bottlenecks.
3. Regular Maintenance
Periodically check your main bus for any issues, such as slowdowns or blockages. Regular maintenance will help you identify and resolve problems before they escalate.
4. Experiment with Different Designs
Don’t be afraid to experiment with your main bus design. Each player has a unique playstyle, and finding what works best for you can lead to improved efficiency and enjoyment of the game.

Frequently Asked Questions
What is a main bus in Factorio?
A main bus is a centralized system for transporting resources, where multiple production lines draw from a shared set of belts carrying essential materials like iron plates, copper cables, and circuits. This helps streamline production and organization in your factory.
How do I design an efficient main bus layout?
To design an efficient main bus layout, start with a long, straight section of belts that runs the length of your factory. Use multiple lanes for different resources, ensuring each lane is dedicated to a specific material. Leave room for expansion and consider using underground belts to manage intersections and avoid congestion.
What resources should I include on my main bus?
Include essential resources such as iron plates, copper plates, steel plates, circuits (green, red, and blue), plastic, and iron gears. Depending on your factory's needs, you may also want to add modules and additional advanced materials as needed.
How many lanes should my main bus have?
The number of lanes on your main bus depends on your production needs. A common setup is to have at least 4-8 lanes for the most critical resources, but you can expand this as your factory grows. It's important to leave space for future expansions.
What are some common mistakes to avoid when setting up a main bus?
Common mistakes include overcrowding the bus with too many resources, failing to plan for future expansion, and not using adequate splitting and merging techniques. It's also important to manage the flow of resources effectively to avoid bottlenecks.
How can I efficiently connect my production facilities to the main bus?
Use splitters and underground belts to connect production facilities to the main bus while minimizing congestion. Ensure that your production buildings are aligned with the bus lanes to facilitate easy access and consider using priority splitters to manage resource allocation.
