About this Mod
Create Track Map: Fork²
A live web map of your Create train network, rebuilt for scale. Same map, dramatically faster on huge networks.
⚠️ This is a fork of a fork. It is not the original and not AyOhEe's unofficial fork. If your network is small, just use one of those.
Why this exists
Original CTM was built around full-state polling and a Leaflet SVG renderer. Both fall over past a few hundred track segments. This fork keeps the user-visible behaviour identical and rewrites everything underneath:
- OpenLayers canvas renderer with incremental updates
- Single SSE endpoint with delta updates instead of four full-state streams
- Train motion interpolated client-side; server polls at 1 Hz instead of 2 Hz
- Gzip on the wire, 3-decimal coords, server-side curve flattening
- Per-edge caches and a topology short-circuit so static networks cost almost nothing per tick
Result on a stress test (3000 segments, 200 signals, 20 trains, 5 clients):
| upstream | this fork | |
|---|---|---|
| Wire bytes/s | ~6.4 MB/s | ~3 KB/s |
| Browser ops/tick | ~6000 DOM | ~20 features |
Compatibility
| Minecraft | Loader | Create |
|---|---|---|
| 1.21.1 | NeoForge 21.1.x | ≥ 6.0 |
| 1.20.1 | Forge 47.1.x (also NeoForge 1.20.1) | ≥ 6.0.6 |
Wire protocol break
The four *.rt SSE endpoints are replaced by /api/v2/stream. Legacy REST GETs still work. Third-party clients on the old streaming API need updating.
