Overhauls Lost Cities underground railways with Create tracks and provides powerful autoloader & spawning utilities.

Supports NeoForge | Forge - Minecraft 1.21.1 & 1.20.1

Create: Lost Cities Subways is a powerful utility and integration mod designed specifically for modpack developers building around The Lost Cities and Create.

First, it fundamentally transforms the underground landscape by replacing tiny vanilla minecart tunnels with massive, functional 16x16 subway tunnels explicitly designed for your Create trains.

Secondly, it serves as a robust background utility: it includes an Autoloader to force default profile selection, a custom player spawn director, and a background cleanup script to fix Lost Cities ghost block entities.

Structures

Massive Create Tunnels - Vanilla minecart railways are fully replaced with custom 16x16 subway tunnels, complete with integrated create:track rails.

Features

Modpack Ready - Built specifically to give modpack makers fine-grained control over how their Lost Cities worlds are initialized.
Built-in Datapack - Railway replacements are handled natively via a built-in createcities resource/datapack.
Profile Autoloader - Automatically forces The Lost Cities to load a specific configuration profile (bypassing the need for players to manually configure world creation settings).
Custom Spawn Director - Allows modpack makers to explicitly define the exact dimension, coordinates, and facing direction where players will spawn upon world creation.
Ghost Block Cleanup - Includes a background ChunkCleanupListener that actively hunts down and removes ghost block entities caused by Lost Cities' structure_void carving, significantly reducing log spam and lag.
