12train — SNCF Train Ticket Search

Query 12train.com, an official SNCF ticket reseller. Find routes, schedules, check detailed pricing conditions (TGV, TER, Eurostar), handle multi-passenger groups with discount cards, and evaluate round-trip discounts.

Base command: uv run /root/.moltis/skills/12trains-skill-moltis/scripts/12train.py

Core Commands

Autocomplete / Resolve Stations

Always use this first to resolve city names into exact SNCF API accepted station names before running searches.

uv run /root/.moltis/skills/12trains-skill-moltis/scripts/12train.py stations "Paris"
uv run /root/.moltis/skills/12trains-skill-moltis/scripts/12train.py stations "Lyon"

Search One-Way Trains

Basic one-way lookup. Defaults to 1 Adult.

uv run /root/.moltis/skills/12trains-skill-moltis/scripts/12train.py search \
  --origin "Paris (toutes gares)" \
  --destination "Lyon (toutes gares)" \
  --date "10/04/2026" \
  --hour 8

Advanced Search Features

1. Custom Passengers & Discount Cards

Use repeating --passenger flags. Format as AGE_GROUP or AGE_GROUP:DISCOUNT_CARD.

uv run /root/.moltis/skills/12trains-skill-moltis/scripts/12train.py search \
  --origin "Paris" --destination "Bordeaux" --date "12/04/2026" --hour 9 \
  --passenger adult \
  --passenger youth:avantage_jeune \
  --passenger senior:avantage_senior

• Age Groups: baby (0-3), child (4-11), youth (12-25), adult (26-59), senior (60+)
• Discount Cards: avantage_jeune, avantage_adulte, avantage_senior, avantage_week_end, liberte, famille_30, famille_40, famille_50, famille_75, militaire_1, militaire_2

2. Intermediate Waypoints (Via)

Force the journey to make a connection at a specific station.

uv run /root/.moltis/skills/12trains-skill-moltis/scripts/12train.py search \
  --origin "Paris" --destination "Nice" --date "10/04/2026" --hour 8 \
  --via "Marseille Saint-Charles"

Round Trips & Contextual Bookings

Basic Round-Trip Search

Fetches both Outward and potential Return journeys contextually.

uv run /root/.moltis/skills/12trains-skill-moltis/scripts/12train.py search \
  --origin "Paris" --destination "Lyon" \
  --date "10/04/2026" --hour 8 \
  --return-date "15/04/2026" --return-hour 18

Optimize: Skip Return Fetch but keep Round-Trip Discounts

Applying a return date can dynamically discount Outward tickets (e.g. "aller-retour" pricing). If you only want to retrieve Outward prices without burning time/bandwidth evaluating Return tickets yet, use --skip-return.

uv run /root/.moltis/skills/12trains-skill-moltis/scripts/12train.py search \
  --origin "Paris" --destination "Lyon" \
  --date "10/04/2026" --hour 8 \
  --return-date "15/04/2026" --return-hour 18 \
  --skip-return

Match Return Options to an Outward Choice

If a user selects a specific Outward train (from the resulting JSON, find its bo_key), use --outward-bo-key to generate Inward Return options perfectly calibrated to that exact reservation leg without retrieving Outward options again.

uv run /root/.moltis/skills/12trains-skill-moltis/scripts/12train.py search \
  --origin "Paris" --destination "Lyon" \
  --date "10/04/2026" --hour 8 \
  --return-date "15/04/2026" --return-hour 18 \
  --outward-bo-key "89a8d876-81c7-4793-c90f-c32d6f73d7c1"

How to Use This Skill

When the user asks about train travel in France:

1. Resolve Stations: Always start with stations command. Example: User asks for "Chambéry", you run stations "Chambery" and receive "Chambéry - Challes-les-Eaux".
2. Setup Defaults: Assume departure hour 6 (06:00) if not specified to show a full day's results. Default to 1 adult if no demographic is provided.
3. Conversational Multi-Step Booking Flow:
   • A. User says "I want a round-trip from Paris to Lyon."
   • B. Formulate outward context with --skip-return to show Outward choices with accurate round-trip discounts natively applied.
   • C. Determine User's choice and extract its bo_key.
   • D. Call the identical command appending --outward-bo-key <bo_key> to securely produce Return choices based on their previous selected path.
4. Clarify Pricing: Prices are delivered dynamically per-train. Present the specific fare_name and fare_condition (like "Standard Première - Echangeable sous conditions") so the user distinguishes between standard, refundable, or flex pricing variants in the same class.
