Important Notes for AI Assistant
⚠️ Station Name Resolution Warning
CRITICAL: When querying by city name (e.g., "武汉", "上海", "深圳", "广州"), the API may return trains from/to ANY station in that city, not just the main station.
Common Pitfalls:
- 武汉 includes: 武汉站 (main), 汉口站 (Hankou), 武昌站 (Wuchang), 武汉东站
- 上海 includes: 上海虹桥 (Hongqiao), 上海站 (main), 上海南站, 上海松江站
- 深圳 includes: 深圳北站 (main), 深圳站 (Luohu), 福田站, 深圳东站
- 广州 includes: 广州南站 (main), 广州站, 广州东站, 广州北站
Best Practice - Always verify exact stations:
- First, use
stations.mjs to list all stations in the city:
node {baseDir}/scripts/stations.mjs 武汉
- Then, query with exact station names for accurate results:
node {baseDir}/scripts/query.mjs 武汉 上海虹桥 -f md
🔄 Transfer/Connection Guidelines
When planning transfers (中转):
- Use JSON output (
--json) to verify exact station names
- Ensure both segments use the SAME station (e.g., both use 武汉站, not 武汉→汉口)
- Recommended minimum transfer time: 20-30 minutes for same station
- Different stations in same city require additional travel time (e.g., 武汉→汉口 = 30+ min by subway)
📋 Query Workflow Recommendation
For accurate results, follow this workflow:
-
List stations in departure city:
node {baseDir}/scripts/stations.mjs 北京
-
List stations in arrival city:
node {baseDir}/scripts/stations.mjs 上海
-
Query with exact station names (e.g., 北京南 → 上海虹桥):
node {baseDir}/scripts/query.mjs 北京南 上海虹桥 -d 2026-03-05 -f md
-
For transfers: Always verify both segments use the same station by checking fromStation and toStation in JSON output.
Technical Notes
- Data comes directly from 12306 official API (no key needed)
- Station data is cached for 7 days in
{baseDir}/data/stations.json
- Works for all train types: G (高铁), D (动车), Z (直达), T (特快), K (快速)
