# Deutsche Bahn Skill

Search German train schedules and plan journeys using the `db-vendo-client` library (open-source client for bahn.de APIs).

**No API key required.** No Docker. Just Node.js.

**Source:** [db-vendo-client](https://github.com/public-transport/db-vendo-client) — wraps bahn.de's internal APIs.

## Setup

```bash
cd skills/deutsche-bahn && npm install
```

## Commands

### Station Search

Find station IDs by name:

```bash
node skills/deutsche-bahn/scripts/search_trains.mjs stations "Frankfurt Flughafen"
```

### Journey Planning

Search train routes between two stations (by ID or name):

```bash
# By station ID
node skills/deutsche-bahn/scripts/search_trains.mjs journeys 8070003 8000376 --date 2026-05-05 --time 10:00 --results 5

# By station name (auto-resolves to ID)
node skills/deutsche-bahn/scripts/search_trains.mjs journeys "Frankfurt Airport" "Germersheim" --date 2026-05-05
node skills/deutsche-bahn/scripts/search_trains.mjs journeys "Amsterdam Centraal" "Mannheim Hbf" --date 2026-05-15 --time 09:00
node skills/deutsche-bahn/scripts/search_trains.mjs journeys "Paris Est" "Mannheim" --date 2026-05-05
```

### Departure Board

Check upcoming departures from any station:

```bash
node skills/deutsche-bahn/scripts/search_trains.mjs departures "Mannheim Hbf" --results 10
node skills/deutsche-bahn/scripts/search_trains.mjs departures 8070003 --date 2026-05-05 --time 14:00
```

| Date | `--date` | Today | YYYY-MM-DD format |

## Coverage

- **All German trains:** ICE, IC/EC, RE, RB, S-Bahn
- **International:** ICE to AMS/Brussels/Paris/Zürich/Wien, TGV to Paris, Eurostar connections
- **Local transit:** S-Bahn, U-Bahn, trams, buses (if DB data includes them)

## Limitations

- **No pricing.** DB does not expose ticket prices via API. For fares, check bahn.de directly or use the Trainline API.
- **Rate limits.** DB's backend enforces low rate limits. Keep queries reasonable (a few per minute, not hundreds).
- **Schedule data only.** Real-time delays are shown when available, but historical data is not retained.
- **Future schedules.** DB typically publishes schedules ~6 months out. Dates beyond that may return no results.

## When to Use

Load this skill when:
- Planning train connections from a European gateway airport to a destination in Germany
- Checking ICE/TGV schedules between major cities
- Finding last-mile S-Bahn/regional connections (e.g., Mannheim → Germersheim)
- Comparing train travel time from different airports to decide which to fly into
- Looking up departure boards at a station

Do NOT use for:
- Booking tickets (search only — book at bahn.de or trainline.com)
- Flight searches (use Duffel, Ignav, Skiplagged, etc.)
- Pricing (not available via API)
