List the Haramain High-Speed Railway (HHR) stations and their ids.

The HHR line runs Makkah <-> Jeddah (two stations) <-> KAEC <-> Madinah. Use these names or ids with search_trains.

Search Haramain (HHR) train schedules between two stations on a date.

Args: from_station: Origin station name or id (e.g. "Makkah", "Jeddah", 1). Plain "Jeddah" resolves to Al-Sulimaniyah; use "Jeddah Airport" for KAIA. to_station: Destination station name or id (e.g. "Madinah", 5). date: Travel date in ISO format YYYY-MM-DD (e.g. "2026-06-30").

Returns a list of trains with departure/arrival datetimes, duration, number of stops, and the intermediate stations. Fares are not included (HHR does not expose pricing on the public timetable).

Search SAR intercity trains (East + North lines) WITH fares on a date.

Covers the non-Haramain network: the East line (Riyadh <-> Abqaiq, Hofuf, Dammam) and the North line (Riyadh <-> Majmaah, Qassim, Hail, Al-Jouf, Qurayyat). Use this instead of search_trains for any route NOT on the Makkah-Madinah Haramain line.

Args: from_station: Origin name or code (e.g. "Riyadh", "RYD", "Dammam"). to_station: Destination name or code (e.g. "Dammam", "DMM", "Hofuf"). date: Travel date, ISO format YYYY-MM-DD.

Returns each train with departure/arrival time, duration, stops, and Economy + Business fares in SAR. Rendered from the public booking results page via a headless browser (~5-10s). An empty list means SAR is not selling that route on that date (the North line currently shows no bookable service; the East line runs daily).
