1. Understanding China's high-speed rail network
China's high-speed railway system connects major metropolitan areas as well as an increasing number of regional cities. Beijing, Shanghai, Guangzhou, Shenzhen, Chengdu, Xi'an, Wuhan, Hangzhou, Nanjing and many other destinations are linked by fast intercity services.
By the end of 2025, China's operational high-speed rail network had exceeded 50,000 kilometers. The scale of the system makes train travel useful not only for individual city pairs but also for multi-city itineraries across large parts of the country.
High-speed rail is commonly referred to in Chinese as gaotie, written 高铁.
2. G, D and C trains
When searching Chinese railway schedules, travelers commonly encounter train numbers beginning with G, D or C. These letters identify different categories of fast passenger services.
G trains generally include the fastest long-distance high-speed services. D trains are also fast electric multiple-unit services and operate across many intercity and longer-distance routes. C trains are commonly used for intercity services between cities within the same region.
The actual speed, stopping pattern and journey time depend on the route, so the train number and timetable are more useful than assuming every train within one category operates identically.
3. Buying train tickets
The official China Railway booking platform is 12306. Tickets can be purchased through the 12306 website or app, at railway station ticket counters and through authorized sales channels.
Foreign travelers can use the English version of 12306. Identity verification is required before purchasing tickets online, and valid foreign passports are accepted for registration and ticketing.
Official guidance also states that foreign travelers can pay online using supported Chinese or foreign bank cards as well as available mobile payment methods.
Third-party booking services may offer a simpler interface or additional customer support, but travelers should compare any service fees and booking conditions before paying.
4. Your passport is part of the ticketing process
China uses real-name railway ticketing. For foreign travelers, the passport information used to purchase the ticket is tied to the journey.
Keep the passport used for booking with you when traveling. On routes using electronic tickets, the valid identity document associated with the booking is used during station entry, boarding or inspection procedures rather than relying on a printed itinerary as the ticket itself.
Check that your name and passport number are entered correctly when purchasing the ticket. Correcting identity details after booking can be more complicated than checking them carefully before payment.
5. Choosing a seat class
High-speed trains can offer several seating classes depending on the train and route. Second class is the standard choice for most passengers and usually provides comfortable airline-style seating. First class generally offers wider seats and more personal space.
Some services also offer business class, with substantially more space and more premium seating. Business class is significantly more expensive and is not available on every train.
For most travelers, second class provides a good balance between price and comfort, especially on journeys of a few hours.
6. What the journey is like
Modern Chinese high-speed trains are designed for long-distance intercity travel, with assigned seating, climate control, luggage storage and onboard toilets.
Food and drink availability varies by service. Some trains have trolley service or onboard food options, but it can still be useful to bring water and snacks, particularly for longer journeys.
Internet access and mobile connectivity can vary considerably by train, route and location. Do not depend on continuous high-speed internet for essential work during the journey.
7. Navigating Chinese railway stations
Large railway stations in China can function more like airport terminals than small traditional train stations. Passengers typically pass through identity and security checks before entering the departure area.
Major cities may have several railway stations, and they can be far apart. Beijing Railway Station, Beijing South and Beijing West, for example, are different stations. The same applies in cities such as Shanghai, Guangzhou and Shenzhen.
Always check the exact departure station before leaving your hotel. Arriving at the right city but the wrong station can mean missing the train.
Allow enough time for transportation to the station, security, finding the correct waiting area and reaching the platform. Extra time is particularly useful when using an unfamiliar station for the first time.
8. High-speed rail or domestic flight?
High-speed rail can compete very effectively with flying on many medium-distance routes, but there is no universal distance at which the train is always better.
A flight may have a shorter scheduled travel time while still requiring a longer journey to the airport, earlier arrival, security procedures and transportation from the destination airport. Rail travel often involves less pre-departure time and may connect more conveniently with urban transportation.
On longer routes, flying can still save substantial time. The best choice depends on the particular cities, train schedule, airport locations, fare and your tolerance for connections or airport procedures.
- Compare total door-to-door journey time, not only scheduled train or flight time.
- Check where the railway station and airport are located.
- Compare ticket prices for your actual travel date.
- Consider baggage requirements and restrictions.
- Look at departure frequency and how flexible your schedule needs to be.
- Consider whether arriving directly by rail makes the next part of your journey easier.
9. Popular travel corridors
Some of the most useful high-speed rail journeys connect major city pairs and regional travel corridors. Beijing and Shanghai are linked by frequent high-speed services, while the network around Shanghai also makes cities such as Hangzhou, Nanjing and Suzhou easy to combine in one itinerary.
In southern China, high-speed lines connect Guangzhou and Shenzhen with other cities in the Pearl River Delta and the wider national network. Western and central cities including Chengdu, Chongqing, Xi'an and Wuhan are also major rail hubs.
Instead of thinking only in terms of one return journey, high-speed rail can make open-jaw or multi-city travel practical: arrive in one city, continue through several others by train and fly home from a different destination.
10. Book important journeys before busy travel periods
China's railways carry enormous passenger volumes, and popular trains can become difficult to book during major national holidays and other peak travel periods.
If a particular train is important to your itinerary, avoid assuming that seats will remain available until the last moment. This is especially relevant around the Spring Festival travel period and major public holidays.
Schedules, availability and ticket-sale rules can change, so check current information through China Railway 12306 when planning the journey.
