Show HN: Offline-first UK train planner

https://railraptor.com
Hey HN! I'd like to share my personal experiment with a different way of finding train journeys across the UK.

When I book flights, I use sites like Kiwi and Skyscanner for flexible searches - multiple airports, custom connections, creative routes, etc. But rail search feels oddly constrained. All the UK train operators offer basically the same experience, and surface the exact same routes. I always suspected there were better or just different options that weren’t being shown. Where is the "Skyscanner for trains"?

After digging through the national rail data feeds, I decided to have a go at building my own route planner that runs completely offline in the browser. This gave me the freedom to implement more complex filters, search to/from multiple stations, and do it without a persistent network connection.

Now I'm finding routes that aren't offered by the standard train operators, connecting at different stations, and finding it's often easier to travel to different stations (some I'd never heard of) that get me closer and faster to where I actually want to go!

It's still a little rough and I'd like to add more features such as fares, VSTP data, and direct-links to book tickets, but wanted to share early and get some initial feedback before investing more time into it. So, thanks in advance - let me know what you think.

Shockingly fast. Have you considered supporting other countries, maybe all of europe?

Thanks for the feedback!

I'd love to support more countries, but from what I can tell it's a mammoth task. Every country publishes rail data in different ways - there are aggregator APIs to join them up, but they don't come cheap.
