Show HN: Ask questions about the Swiss train timetable

2•bekoeppel•43m ago

I use the SBB website and app every day to find my Swiss train journeys, but even with the touch tiles I find it cumbersome to use, especially for extra filters like avoiding bus or finding trains with space for bicycles.

So I built https://fragplan.ch/ to describe a train journey in natural language, and translate it into an SBB timetable request. I'm especially happy about the many settings one can make on SBB.

The name is a play on the words "fragen" (to ask) and "Fahrplan" (timetable).

I wish there was something like this directly in the SBB app...

Nice. I tested a very simple example and got exactly what I hoped. Is there a LLM behind it or some more traditional kind of AI?

I built a combination of rules (e.g. HB is translated to Zurich HB) and LLM (Haiku). The rules were necessary because if I send a user to SBB.ch with destination "HB", SBB translates that to Herzogenbuchsee... not what I had expected.
