China High-Speed Trains Explained: G, D, C Trains, Speeds & Top Routes (2026)
China runs the largest high-speed rail (HSR) network on Earth — more than 50,000 km of track in 2026, roughly two-thirds of the world's total. For visitors, this means you can cross half the country in an afternoon, skip airport security lines, and arrive in the city centre instead of a distant airport. But the first time you look at a Chinese train ticket, the letters in front of the train number (G, D, C, Z, T, K) can be confusing. This guide explains exactly what each code means, how fast each train goes, and how to pick the right one for your route.

What the train letter codes mean
Every Chinese train number starts with a letter (or is all-digits for the slowest services). The letter tells you the train's speed class and comfort level — it is the single most useful thing to read on a timetable.
| Code | Name | Top speed | What it is |
|---|---|---|---|
| G | Gaotie | up to ~350 km/h | Fastest high-speed trains, fewest stops, modern Fuxing/CRH trainsets |
| D | Dongche | 200-250 km/h | Earlier-generation high-speed EMU; more stops, often cheaper |
| C | Chengji | up to ~200-350 km/h | Intercity shuttles between neighbouring cities (e.g. Beijing-Tianjin) |
| Z | Zhida | up to 160 km/h | Conventional non-stop/express overnight trains with sleepers |
| T | Tekuai | up to 140 km/h | Conventional express, stops only at major cities |
| K | Kuaisu | up to 120 km/h | Conventional "fast" trains, many stops, cheapest with sleepers |
G, D and C are the high-speed (bullet) trains you will use most as a tourist. Z, T and K are conventional trains — slower, but they reach smaller towns and offer overnight sleeper berths that high-speed lines do not.
G, D and C trains in detail
G trains are the headline act. Run by modern Fuxing and CRH trainsets, they cruise at a scheduled 350 km/h on dedicated passenger lines — the fastest scheduled trains in commercial service anywhere in the world. G trains make the fewest stops, so they are the quickest option on long corridors like Beijing-Shanghai.
D trains are the slightly older "bullet train" generation, running 200-250 km/h. They tend to stop at more intermediate stations and often cost less than a G train on the same route. A few D trains even run overnight with sleeper cabins, which can be a comfortable budget choice.
C trains are short intercity shuttles linking neighbouring cities — think Beijing to Tianjin (about 30 minutes) or Guangzhou to Shenzhen. They run frequently, almost like a metro between cities.

Journey times on top routes (2026)
High-speed rail has rewritten travel times in China. Here are the fastest scheduled durations on the most popular tourist corridors:
| Route | Distance | Fastest HSR time | Typical train |
|---|---|---|---|
| Beijing - Shanghai | 1,318 km | ~4h 18m | G (Fuxing) |
| Beijing - Xi'an | 1,200 km | ~4h 20m | G |
| Shanghai - Hangzhou | ~170 km | ~32 min | G / D |
| Guangzhou - Shenzhen | ~140 km | ~30 min | C |
On Beijing-Shanghai there are roughly 40-50 high-speed departures a day in each direction, so you rarely wait long. Shanghai-Hangzhou has 270+ daily high-speed trains — you can simply turn up and take the next one.
When to pick which train
- Pick a G train when you want the fastest journey and your route has one (most major city pairs). Worth the small premium for long trips.
- Pick a D train to save money on the same corridor, or for the occasional high-speed overnight sleeper.
- Pick a C train for quick hops between neighbouring cities — they run constantly.
- Pick a Z, T or K train only when there is no high-speed line to your destination, or when you specifically want a cheap overnight sleeper to cover a long distance while you sleep.
For most international visitors sticking to Beijing, Xi'an, Shanghai, Hangzhou and the south, you will ride G and C trains almost exclusively.

What the high-speed experience is like
Chinese HSR is clean, punctual and comfortable. Stations are airport-sized: arrive 45-60 minutes early, pass through a security X-ray, and wait in a large hall until your gate opens about 15 minutes before departure. Bring your passport — it is your ticket and your ID at the gate.
Onboard, second class has comfortable 3+2 seating, power sockets and free (if slow) Wi-Fi; first class is roomier 2+2 seating; business class on G trains offers lie-flat seats. There is a dining car and trolley service, but food is pricey — many travellers bring their own snacks and a thermos for the free hot water dispensers in every carriage.

FAQ
What is the difference between G, D and C trains in China? All three are high-speed (bullet) trains. G trains are the fastest (up to 350 km/h) with the fewest stops; D trains run 200-250 km/h and stop more often; C trains are short intercity shuttles between neighbouring cities. Z, T and K are slower conventional trains.
How fast do China's high-speed trains go? G-class trains run at a scheduled 350 km/h, the fastest in commercial passenger service worldwide. D trains run 200-250 km/h and C trains up to around 200-350 km/h depending on the line.
How long is the high-speed train from Beijing to Shanghai? The fastest G train covers the 1,318 km between Beijing and Shanghai in about 4 hours 18 minutes. Most G services take between 4h 18m and 6 hours depending on the number of stops.
Do I need my passport to take a high-speed train in China? Yes. Your passport is tied to your ticket and you must show it at the station security check and the boarding gate. Bring the same passport you used to buy the ticket.
Are high-speed trains better than flying in China? For trips up to about 1,000-1,300 km, high-speed rail is usually faster door-to-door than flying once you count airport travel, security and check-in. Trains also drop you in the city centre and are rarely delayed.
