Resolución de problemas

Errores comunes y soluciones

Station name not found

Use the station search tool to find the exact name. Chinese station names must match the 12306 database — try both simplified Chinese and pinyin.

Verificar: Search for the station by keyword first
No trains found for the given date

12306 only sells tickets 15 days in advance. Ensure your date is within the booking window.

Verificar: Try a date within the next 15 days
Connection timeout

The 12306 API can be slow during peak booking times (e.g., Spring Festival). Retry after a few minutes.

Verificar: Test with a simple station search to confirm connectivity
