Short answer
Beijing to Nanjing is one of the easiest rail trips in China. High-speed trains run from Beijing South (北京南) to Nanjing South (南京南) in as little as 3 hours 14 minutes, with most services taking 3.5 to 4.5 hours and slower multi-stop trains running past 5 hours. Dozens of departures leave each day, so you can pick a time rather than plan around one.
Unlike the Shanghai–Qingdao corridor, there is a real overnight option here. Overnight D-category high-speed sleeper trains take about 9 hours 30 minutes, and conventional Z, T and K category overnight trains on the older parallel line take roughly 10 to 15 hours depending on how many stops they make.
The one number worth knowing before you book: the corridor runs on a 15-day presale window, and a 2026 pilot lets passengers reserve Beijing–Shanghai corridor trains further out. Confirm both on the official 12306 channel, because the window has moved before and will move again.
What the route actually is
Nanjing sits roughly 1,000 km south of Beijing on the Beijing–Shanghai high-speed line, the same corridor that carries the flagship Beijing–Shanghai trains. Your train is doing the first two-thirds of that run.
That matters for two reasons. First, the corridor is one of China's busiest, which is why you get so many daily departures and a genuine spread of journey times. Second, it is also one of the most heavily policed by demand: during Spring Festival, the May holiday and the National Day week, second class on the most convenient departures sells out well before the travel date.
Nanjing is not a stopover city that you clear in half a day. It was the capital of several dynasties and again in the twentieth century, and the surviving Ming city wall is one of the longest and best-preserved urban walls anywhere. Purple Mountain, west of the city, holds the Sun Yat-sen Mausoleum and the Ming Xiaoling tomb. The old Confucius Temple quarter sits on a canal in the south of the city centre.
If you are continuing, Nanjing is also a hinge: Hangzhou and Shanghai are both a short onward hop from here, which is why the Shanghai–Hangzhou leg shows up in a lot of Beijing itineraries.
Which station to use in each city
| Station | Chinese name | What it is and when to use it |
|---|---|---|
| Beijing South | 北京南 | The high-speed departure point for Nanjing and the whole Beijing–Shanghai corridor. If you are on a G or D train, this is your station. |
| Beijing Station | 北京站 | Conventional trains, including some overnight sleepers. Older building, central location, different passenger flow. |
| Beijing Fengtai | 北京丰台 | Used by a number of services that would otherwise crowd Beijing Station. Check the station code before booking a taxi. |
| Nanjing South | 南京南 | Huge modern station south of the city centre in Jiangning, with metro lines running under it. Where high-speed trains arrive. |
| Nanjing Station | 南京站 | North of the centre, right on Xuanwu Lake and the city wall. Where conventional and sleeper trains usually arrive. |
Daytime high-speed or overnight sleeper?
Three hours and a bit is short enough that the overnight version is normally a wasted night rather than a saved hotel bill. The sleeper exists, it is real, and it is worth understanding — but on this route it makes most sense if you are pushed for daytime hours, or if you are a rail enthusiast who wants the experience.
| Option | Typical journey time | When it makes sense |
|---|---|---|
| G-category high-speed, daytime | About 3h 14m at the fastest; 3.5–4.5h typical | Almost always. Arrive in Nanjing before lunch, lose no night. |
| D-category high-speed sleeper, overnight | About 9h 30m | When you want to sleep through the trip and the train times suit your arrival. |
| Z, T or K conventional sleeper, overnight | Roughly 10–15h depending on stops | Cheapest berths, most stops, slowest of the three. Compare carefully before choosing. |
An overnight train that takes nine and a half hours to cover a distance the daytime service does in three is not efficient travel, it is a bed that moves. Judge it that way. Berth types, privacy and cost differences are laid out in our train sleeper guide.
Seat classes on this route
G and D trains carry the standard high-speed classes. Sleeper trains carry a different set entirely, and the two do not overlap, so what you can buy depends on which type of train you pick.
| Train type | Classes available | Notes |
|---|---|---|
| G (high-speed) | Second, first, business | Second class is 3+2; first is 2+2; business is the lie-flat or wide-seat option at roughly three times the second-class fare. |
| D (high-speed, includes sleepers) | Second, first, plus sleeper berths on night services | Sleeper berths on D trains are the newer 4-berth or vertical layout, not the classic 6-berth cabin. |
| Z, T, K (conventional) | Hard seat, soft seat, hard sleeper, soft sleeper, deluxe soft sleeper on some Z trains | Soft sleeper is a four-berth compartment with a door. Hard sleeper is an open six-berth bay in an older carriage. |
For a 3.5-hour daytime run, second class is the correct default and the difference between it and first class is comfort, not arrival time. Full breakdown of legroom, recline and luggage space by class is in train seat classes in China.
Booking with a foreign passport, and the booking window
Two windows are worth knowing on this specific corridor, and they are not the same thing.
- The standard presale window has been 15 days ahead of departure, with sales continuing until roughly 30 minutes before the train leaves. This applies across the network and is the number to plan around.
- A reservation pilot on the Beijing–Shanghai corridor was announced for 2026, letting passengers submit reservation requests from 60 days to 17 days before departure through a dedicated appointment section in the 12306 app, with the railway fulfilling those orders from 20 to 16 days out. Reported details of the pilot are thin and it has changed since launch, so treat it as a possible head start rather than a promise, and check whether it covers your exact train inside the app.
- Verify the passport before you need ticketsRegister in the 12306 app with the passport number and spelling exactly as printed. Foreign-passport verification is the step that most often delays a first booking, and it is not instant in every case.
- Set an alarm for the opening dayOn a corridor this busy, popular morning departures go quickly on the day the window opens — and within minutes on a public holiday release day.
- Consider the slower train on release dayThe multi-stop services that take five hours are usually still available when the three-hour trains are gone. Arriving two hours later beats arriving a day later.
- Use the waitlist rather than giving up12306 resells cancelled tickets continuously, and extra capacity is released on busy corridors as departure approaches. A waitlisted booking often clears.
- Know the change and refund rulesThey depend on how far ahead of departure you act, and they are stricter for changes close to departure. Details are on our ticket refund and change page.
Book through the official 12306 English app unless you have a reason not to. Third-party sellers add a fee, and when a change or refund is needed they add a queue as well.
How fares work
Fares scale with class and with the number of stops a train makes. As a shape rather than a quote: a published fare table for the full Beijing–Shanghai run lists second class at ¥553, first class at ¥933 and business class at ¥1,748 — a ratio of roughly 1 : 1.7 : 3.2. Beijing–Nanjing is a shorter leg and sits in a lower band, with the same proportions.
Sleeper berths follow their own logic. A soft sleeper on a Z-category train often costs more than a second-class seat on a G train, while a hard sleeper costs considerably less. If price is the deciding factor, price the sleepers properly before assuming the high-speed option is the expensive one.
Check the exact figure on 12306 for your date. No third-party page, including this one, will be more accurate than the railway's own system.
On board and on arrival
A three-and-a-half-hour G train is a pleasant ride. Seats are assigned by carriage and number, there is a trolley service, and the overhead racks take a cabin bag. Larger cases go in the racks at the end of each carriage.
Buy food before boarding. Station concourses have far better options than the train buffet, and Beijing South has plenty of shops on the departure level. On a run this short, many travellers eat before or after rather than on board, which is a reasonable plan.
Allow real time at Beijing South. Security screening and the walk to the platform are not fast at peak periods, and boarding closes a few minutes before departure. Forty-five minutes before departure is comfortable, an hour on a holiday is safer.
Frequently asked questions
How long does the train take from Beijing to Nanjing?
The fastest high-speed trains cover it in about 3 hours 14 minutes. Most services take 3.5 to 4.5 hours, and slower trains with more stops run past 5 hours. Overnight sleeper options take roughly 9 to 15 hours depending on the type of train.
Is there an overnight sleeper train from Beijing to Nanjing?
Yes, and it is a genuine alternative here. Overnight D-category high-speed sleeper trains take about 9 hours 30 minutes, and conventional Z, T and K category overnight trains take roughly 10 to 15 hours. This is a different situation from the Shanghai–Qingdao corridor, which has no practical overnight service.
Which Beijing station do trains to Nanjing leave from?
Beijing South (北京南) for G and D high-speed trains. Some conventional and sleeper services use Beijing Station or Beijing Fengtai instead. The station is printed on your ticket and on the booking screen — check it, because the three are in different parts of the city.
Is Nanjing South or Nanjing Station better for sightseeing?
Nanjing Station is closer to the old centre and sits right beside Xuanwu Lake and the city wall, so it is the better arrival if your hotel is around Xinjiekou, Fuzimiao or the wall. Nanjing South is further out but has better metro connections and is where high-speed trains arrive, so it is usually the more practical hub.
How far in advance can I book Beijing to Nanjing tickets?
The standard presale window has been 15 days before departure, with sales running until about 30 minutes before the train leaves. A 2026 pilot on the Beijing–Shanghai corridor lets passengers submit reservations from 60 days to 17 days ahead through a dedicated section of the 12306 app. Confirm the current window inside the app, as it has changed before.
How much is a second class ticket?
It varies with the specific train and class. On the Beijing–Shanghai corridor a published fare table shows second class at ¥553, first class at ¥933 and business class at ¥1,748 for the full run, which is a ratio of roughly 1 : 1.7 : 3.2. Beijing–Nanjing is a shorter leg at a lower level, with the same proportions. Check the exact fare on 12306 for your date.
Can I travel to Nanjing on a foreign passport?
Yes. Register in the China Railway 12306 app with your passport, complete identity verification, and travel on the passport itself. China uses e-tickets, so there is usually nothing to collect. If the automatic gate will not read a foreign passport, use the staffed lane.
Do I need to book in advance or can I buy on the day?
On ordinary weekdays there is often same-day availability on the slower departures. On the faster trains, and across Spring Festival, the May holiday and National Day week, book as soon as the window opens. The corridor is one of the busiest in the country.
Is the sleeper cheaper than the high-speed train?
It depends on the berth. A hard sleeper on a Z-category train usually costs less than a second-class seat on a G train, but a soft sleeper often costs more. Price the berth types individually rather than assuming the slower train is the cheap one.
How busy is Beijing South station?
Very. It is one of the main hubs on the Beijing–Shanghai corridor, and security screening plus the walk to the platform takes time at peak periods. Arriving 45 minutes before departure is comfortable; allow an hour during public holidays.
