Optimize World Generation with Existing Rail Systems

Natural Rail Generation

Some worlds or modpacks include naturally generated train tracks. Without optimization, these distant tracks cause lag as the game tries to connect them across unloaded chunks.

Playing in Worlds with Pre-Built Rails

1. No action needed: The mod automatically prevents lag from existing rail systems.

2. Explore safely: Travel through your world without stuttering from distant track processing.

3. Build your own network: Add your personal rail system without interference from world-generated tracks.

Performance Benefits

  • Distant naturally-spawned tracks won't slow down chunk loading.
  • Your game stays responsive even in worlds with extensive pre-built rail infrastructure.
  • The mod works silently—you don't configure or manage anything.

Combining Systems

If you want to connect to existing generated tracks:

  • Travel to them and load the chunks they occupy.
  • Build your own tracks into the loaded area.
  • Connections form naturally as chunks load.

This approach keeps your world fast while letting you integrate with any existing rail systems.
