trains
This skill queries UK National Rail Darwin/Huxley APIs for live departures, arrivals, delays, and services. It requires the `NATIONAL_RAIL_TOKEN` env var and runs `./scripts/trains.py`/`./scripts/trains.sh`, making network requests to `https://huxley2.azurewebsites.net` and `https://lite.realtime.nationalrail.co.uk/OpenLDBWS/ldb12.asmx`.
