Train types and seat choices

The prefix is a starting point

G, D and C commonly identify high-speed or intercity services; Z, T and K appear on conventional services. The prefix alone is not a promise of a particular speed, travel time or seat layout. Use the actual service listing on 12306 for the date you plan to travel.

Choose for the journey

Availability varies by train. A seat class that exists on one service may not appear on another.

• Second class: the usual starting point when comparing seated high-speed services.
• First and business class: compare the actual fare and seating product before deciding whether the extra space matters for your journey.
• Hard and soft sleepers: check berth type, position and compartment details; do not assume every overnight train has the same layout.
• Seat or standing products: read what is being sold carefully, especially during busy periods.

Check the whole connection

Compare departure and arrival stations, travel time, changes and the final local transfer. The rail map here is a planning diagram. It does not show live service schedules, fares or remaining seats.
