About This Service
The Problem
Traditional journey planners answer: "How do I get from A to B?"
But what if you're already on a train that's running late? Existing tools don't help you answer: "I'm on this specific service, arriving at interchange stations at these predicted times—what are my best onward connections?"
How It Works
- Find your train by entering where it departed from and when (or its headcode)
- Select your current position from the calling points list
- Enter your destination and we'll find the best onward connections
We use real-time data from the Darwin Live Departure Boards API, so journey suggestions account for current delays and predicted arrival times.
Features
- Real-time departure information
- Multi-leg journey planning (up to 2 changes)
- Walking connections between nearby stations (e.g., London termini)
- Smart ranking of journey options by arrival time and changes
Limitations
- Currently requires station codes (CRS) — full station name lookup coming soon
- Darwin service IDs are ephemeral; you cannot bookmark specific services
- No fare information — check with your ticket provider for validity
Technical Notes
Built with Rust, using data from the Rail Data Marketplace. This is an independent project and is not affiliated with National Rail, Network Rail, or any train operating company.
Design inspired by the bold, optimistic travel posters of 1930s–50s British Railways.
