PaperTime

May 2026 National Rail timetable explorer. Pure Rust build pipeline. SvelteKit SSG frontend. Render Static Site.

Features

1. Paper Timetable View — given a journey (origin + destination), render the relevant timetable as an interactive HTML table
2. iBRY (Marey) Traffic Flow Graphs — classic time–distance diagrams showing train services as slanted lines
3. Service Pattern Diagrams — interactive schematic diagrams for any station

Development

Prerequisites

• mise — environment manager (Rust, Node, Bun all managed via mise)
• Bun — for the SvelteKit frontend

Build Pipeline

# Run the full data pipeline (Rust pdf2data binary)
mise run data

# Build the SvelteKit static site
mise run build

# Deploy (commit data + push to GitHub → Render auto-deploys)
mise run deploy

# Dev server
mise run dev

Data Strategy

PDFs are source material only — extract once into structured JSON, commit with codebase, render on-demand client-side. No backend, no database, no API routes.
