Train Network Optimisations

by Bawnorton

Train Network Optimisations changes how Create train networks are built on Forge 1.20.1, so large rail systems can be laid out without stalling the game.

What it does

When a player lays track, the game can try to connect pieces that lie outside the chunks currently loaded. This mod prevents those connection attempts, which is the source of the lag spikes that large networks cause during construction and worldgen. Train networks of much greater size can then be built and created in a world. The mod is server-side only, so only the server needs it and players join without installing anything. Files are published for Forge, version 1.20.1 only, with 1.0.1 as the latest file, released under the MIT License as open source.

Key features

  1. Chunk-aware track connections

    Track connections are limited to chunks that are loaded, so distant track is not processed during construction.

  2. Larger train networks

    Networks can grow much larger before the game slows down when new track is placed.

  3. Smoother worldgen

    Train networks generated during worldgen avoid the large lag spikes that unrestricted connection attempts would cause.

What the author says

This mod improves the performance of train network construction by preventing the connection of tracks that are outside of loaded chunks. Originally made for DeceasedCraft by request of TqLxQuanZ but can be used as a standalone.
