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.
