Edward Betts 03d2a53961 Stream GWR walk-on fares client-side instead of blocking page render 
Walk-on fares are now always fetched in the browser via WALKON_API_URLS
rather than synchronously on the server. This means the page renders
immediately with timetable and Eurostar prices, and NR fares fill in
shortly after without delaying the initial load.

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.

Running

flask --app app run

Then open http://localhost:5000.
