The loading page now opens an EventSource to a new ?render=stream endpoint. The server immediately sends a shell event (full page chrome: nav, filters, JS — no external fetches needed), then a section event per direction as each one's NR + Eurostar data arrives, and finally a done event with the summary and timetable-refresh URL. The client slots each section card into a placeholder and calls initialiseResultsPage() only after done, so fares and advance-fare streaming start at the right moment. Adds results_shell.html (shell template with empty JS data globals and mergeSectionData/finaliseResults hooks), results_section.html (extracted section card partial used by both the full and stream render paths), and helper functions _section_trip_fares() and _build_summary_html() to avoid duplicating fare-dict assembly between the two paths.

Bristol Eurostar
Source: https://git.4angle.com/edward/bristol-eurostar
Plan a trip from Bristol Temple Meads to Europe via Eurostar.
Combines GWR trains (Bristol → Paddington) with Eurostar services (St Pancras → destination) and shows all valid same-day connections, including Circle Line times for the Paddington → St Pancras transfer. Displays GWR walk-on fares, Eurostar Standard prices, seat availability, and total journey cost.
Destinations
- Paris Gare du Nord
- Brussels Midi
- Lille Europe
- Amsterdam Centraal
- Rotterdam Centraal
- Cologne Hbf
How it works
Train times and prices are fetched from two sources:
- GWR — scraped from Realtime Trains using httpx
- Eurostar — fetched from the Eurostar GraphQL API (single call returns timetable, Standard fares, and seat availability)
The Paddington → St Pancras transfer uses a real Circle Line timetable parsed from a TfL TransXChange XML file, accounting for walk time to the platform at Paddington and walk time from the platform to the St Pancras check-in.
Results are cached to disk by date and destination.
Connection constraints
Configurable via the search form. Defaults:
| Minimum Paddington → St Pancras | 50 min |
| Maximum Paddington → St Pancras | 110 min |
Valid range: 45–120 min (min), 60–180 min (max).
GWR fares
Walk-on single fares for Bristol Temple Meads → Paddington, selected automatically by departure time:
| Ticket | Price | Restriction (weekdays) |
|---|---|---|
| Super Off-Peak | £45.00 | Not valid 05:05–09:57 |
| Off-Peak | £63.60 | Not valid before 08:26 |
| Anytime | £138.70 | No restriction |
Weekends always use Super Off-Peak.
Setup
pip install -e ".[dev]"
Configuration
Copy or create config/local.py (gitignored) to override defaults:
CACHE_DIR = '/var/cache/bristol-eurostar'
CIRCLE_LINE_XML = '/path/to/output_txc_01CIR_.xml'
Defaults (in config/default.py) use ~/lib/data/tfl/.
The Circle Line XML is a TfL TransXChange timetable file. The Paddington (H&C Line) stop is 9400ZZLUPAH1; the King's Cross St Pancras stop is 9400ZZLUKSX3.
