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):

Compatibility

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.
