Create Track Map: Fork²

Create Track Map: Fork²

A live web map of your Create train network, rebuilt for scale. Same map, dramatically faster on huge networks.

> ⚠️ not It is not the not and not %%MD1%%). 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.
