Railway Constructor v1.0.1 (07 Sep 2025) is a procedural railway generation tool for Unity, designed to enable real-time creation of railway infrastructure. It features multiple rail styles, two train types (a mainland train and a subway with stations), and a spline-based train controller that adapts to existing systems and stops at stations. The tool supports the creation of railways, ramps, turnouts, stations, and seamless intersections, with meshes generated at lightning speed using Unity’s Jobs, Burst, and advanced Mesh API.
Key features include elevation control with automatic bridge, rail, and pillar adjustments based on overlapping parts, terrain fit with height matching, texture blending, and automatic removal of terrain details and trees. The system supports adjustable mesh resolution, automatic LODs, and dynamic vertex count based on slope and curvature. It offers undo and demolition functionality, real-time movement of constructed intersections and connected railways, and clean, optimized meshes for performance.
Railway Constructor is fully compatible in both editor and runtime workflows and supports customizable rail designs through the Inspector, allowing modular building on existing elements or integration of custom styles. The asset is extensible via a public API, with full source code, examples, and accessible data provided for developers to build custom tools. Save and load functionality is included, enabling easy serialization and integration with custom save systems. The tool integrates with Road Constructor, enabling overlap detection and crossing creation, and is compatible with Unity 2022 LTS and later versions.
