The rail network is the single best thing about travelling in China, and the single most intimidating. Both come from the same fact: it is run like an airline, at scale, in Chinese.

China has about 45,000 km of high-speed line — more than the rest of the world combined — and it has quietly replaced domestic flying for most routes under 1,200 km. Beijing to Shanghai takes 4h18 and leaves every twenty minutes.
| Prefix | What it is | Speed | When you will use it |
|---|---|---|---|
| G | High-speed, the backbone | 300–350 km/h | Almost every intercity leg |
| D | Older high-speed / overnight | 200–250 km/h | Cheaper, sometimes overnight |
| C | Intercity commuter high-speed | 200–350 km/h | Short hops between neighbouring cities |
| Z / T / K | Conventional sleeper and slow trains | 80–160 km/h | Overnight budget, remote lines |
| Y | Tourist and scenic lines | 120–160 km/h | Rare, occasionally useful |
Chinese high-speed stations are the size of airports, and most cities have more than one. Beijing has four main stations and they are not interchangeable. The single most common way to miss a train is to go to the wrong station.
Check the station name in Chinese characters on your ticket and match it exactly. “Beijing South” (北京南) and “Beijing West” (北京西) are 40 minutes apart by metro.
Large stations need 20 minutes just to walk to the gate. Security is fast but mandatory.
Bags through a scanner, passport checked. Water bottles may be tested — hold them out.
Boarding is announced on screens about 20 minutes before departure, by train number, not destination.
Chinese high-speed trains close their gates early and do not wait. This is not a soft deadline.
Carriage numbers are marked on the platform. Your seat letter and number are on the ticket; there is no seat selection on most bookings.
Officially each passenger may bring 20 kg (adults) with dimensions up to 130 cm for high-speed trains. In practice, nobody weighs your bag. What matters is whether you can lift it: there are overhead racks for cabin bags and racks at the carriage ends for large cases, and no porters.
The official channel is 12306, which now has an English interface and accepts foreign passports and Alipay. Tickets go on sale 15 days before departure at 08:00 Beijing time and popular routes — Beijing–Shanghai, Xi’an–Chengdu, Guilin–Guangzhou — sell out on holiday weekends within minutes.
You can also buy at the station counter with a passport, which is slower but reliable outside peak dates. Third-party sites add a booking fee and sometimes fail at the payment step; use them only if 12306 refuses your card.
