Welcome to the most epic guide on creating a high-throughput bus in mid-late game. This game is unique, especially when it comes to those cute sparks. But fear not, for I shall demonstrate a possible solution to your logistics nightmare, and the best part? You can start preparing in early game with minimal modifications needed!

These sparks are a bit like cats – they take up the whole path and will crash into each other if they're not careful. But, unlike your cats, you can actually control them. To move more than one hauling spark along the same path, you might think to create a return path or a sorter that returns empty sparks early. But, let's be real, who has time for that?

By applying the principles of the Payday 2 technique, we can create a high-throughput bus that surpasses traditional loop-based designs in both speed and space efficiency.


This method effectively turns sparks into true conveyor belts, allowing for:

• One-way item movement, eliminating the need for return loops
  
• Built-in buffer and back pressure for reliable item transfer
  
• spinning sparks are funny looking

For a factory game, you need a fast and reliable splitter. There are two possible designs for a splitter:

On the right, A traditional splitter, which evenly distributes incoming items into two output streams
On the left, A prioritized splitter, which attempts to fill up the first output stream before moving on to the second

The design for a merger is equally straightforward, using the same logic as the splitter.

By combining multiple item belts onto a single path, we can further increase the throughput of our system. However, be aware that compressing the path can cause unusual behavior in the sparks.

As you attempt to make the design more compact, you may notice that it no longer works as intended. This is because the sparks behave differently when their path is compressed. One such anomaly is the change in output priority, which no longer follows the right-hand rule.

Feel free to comment below if you notice any further unusual behaviors, or if you just want to share your own logistical horror stories.
