Smooth Redstone Rails Mod (1.20.1) – Run Massive Train Networks Without Lag

Smooth Redstone Rails Mod extends Create with performance optimizations and lag fixes for trains. It prevents server freezes and frame drops when running large railway networks with many moving carriages. The mod offloads route calculations to background threads, groups distant carriages, and cleans up chunk loading along railway tracks. It also backports critical fixes from newer versions so worlds stay fast and stable.

Features:

• Level of Detail Scaling: Adjusts train physics and detail levels across four stages depending on how close you are to the tracks.
• Carriage Grouping: Merges multiple train carriages into a single lightweight data group when players walk away.
• Safe Multi-Threading: Calculates schedules, route paths, and collision checks on a separate thread to keep the main game tick fast.
• Trains update less frequently when far away to save processing power.
• Stops rendering hidden carriage parts, distant particle effects, and animations that nobody is watching.
• Replaces complicated train contraptions with lightweight proxy placeholders at long distances.
• Pre-loads track chunks ahead of moving trains and quickly unloads track chunks left behind.
• Stops train stuttering and sudden speed drops when carriages cross unloaded chunk borders.
• Fixes massive lag spikes caused by collision calculations whenever train doors open and close at stations.
• Batches network packets and only sends position updates when train speed or direction changes.
• Sorts train priority at junctions so express and passenger lines do not block freight paths.
• Monitors world tick rates and automatically lowers detail distances when TPS drops below normal.

Configuration:

• create_optimized_trains-common.toml: config file where you can adjust tick update intervals, LOD render distances, and individual optimization toggles.
