Beijing Rail Transit has a unified billing network that includes most of the lines in the city center and major suburbs.There are currently 25 lines in this system (as of August 2024).You only need to enter the station using the allowed method and settle the fee when leaving the station if you are using a stored value card or mobile app.Alternatively, simply purchase a one-way ticket to the final destination.When taking or transferring to trains on different routes, there is no need to purchase tickets or pay separately on the train or before each ride.The fare paid is the cost of the shortest path between the two stations of entry and exit.Passengers are free to choose the transfer station along the way.If accidentally get off at the wrong station or take the wrong direction, take the correct route again until they reach the destinations.However, it should be noted that each passenger is allowed to stay in the paid area for a maximum of 4 hours per trip.After exceeding 4 hours, an additional fee of 3 RMB should be paid.Except for these routes, other routes require separate payment for each ride, it need to be re charged even transferred from the unified billing system.

Except for the railway connect to the airports, the billing method for all other routes is consistent, and the fees are also the same regardless of the payment method used.3 yuan can travel up to 6 kilometers, 4 yuan can travel up to 12 kilometers, 5 yuan can travel up to 22 kilometers, 6 yuan can travel up to 32 kilometers, 7 yuan can travel up to 52 kilometers, and then every 1 yuan can travel up to 20 kilometers.When arriving at the airport, a separate billing method will be used.You can refer to the detailed information about the arrival railway at the airport later. There are no preferential measures for transfers between the unified billing system and other separately lines.

The fare of ordinary buses in Beijing is unified, its standard is the basic fare of 2 yuan, can take 10 km, then 3 yuan can take 10.01 to 15 km, 4 yuan can take 15.01 to 20 km, and so on, without setting the upper limit, for some very long routes, its fare may have dozens of yuan.You need to swipe your card when you get on and off the bus.There are also special express routes with additional fares, such as routes to popular tourist areas. Unlike Singapore or other places, Beijing and the metropolitan area do not have any additional benefits for rail and bus transfers.

Using Beijing urban railways is relatively easy, as long as you no need to buy a one-way ticket, although all routes can be purchased with cash for tickets. However, for foreigners, the method of using cash to purchase tickets for each ride is not very recommended, unless the number of rides is very small, which can be difficult for outlanders, especially foreigners, because it requires some identification to buy. And the number of Chinese people using cash to purchase train tickets is very small now, the number of automatic ticket machines and manual ticket windows that can provide services is very limited. There is also a possibility that some ticket machines refuse cash payment because there is not enough change stored in the machines, so they cannot provide you with change.

If you have already exchanged cash upon arrival in China, you can purchase a transportation card at some transportation hubs as they usually provide manual services. If the card is not damaged, it can be refunded when leaving Beijing, but we suggest that you keep this card because it can be used not only in Beijing, but also in many cities in China. Similarly, the transit cards you purchased in Shanghai, Guangzhou, Hong Kong or other Chinese cities (With the China T-Union icon) can also be used in Beijing.

If you have not exchanged cash or the amount of cash is insufficient, you can use the traffic QR code in Alipay app. It supports binding foreign bank cards and making direct payments, or you can open a traffic card in your iPhone but need a card that can pay RMB.

Almost all lines of the Beijing subway in the city center area are underground, and their entrances are usually formed in independent-one-story high buildings above ground level, with signs of the Beijing subway and the lines that this station can take. Some of them may also be connected to surrounding buildings and directly run into their basements. If it is outside the city center, the routes and stations may be more located at or above ground level, but this does not affect your ability to find and reach the stations. If you need to take trains, just find the building with the sign of Beijing subway hanging on it and walk in, and follow the guidance signs hanging or posted inside. In general, you can easily find where to take the train. The rail transit lines in the center of Beijing are usually named after numbers, while some routes to the suburban are named with Chinese characters, although they also have a numerical number.

There are two railway lines connect to the Badaling Great Wall, one of which is the suburban railway line S2, and the other is the high-speed railway from Beijing to Zhangjiakou. However, the frequency of these two lines is not very much.

Suburban Line S2 departs and arrives at Huangtodian Station, it is connected to the Huoying Station in urban railtransit system, and it can be accessed by Line 8 or Line 13, but it should be noted that urban and suburban rail are charged separately, and you need to leave the station of urban rail and re-enter the station of suburban rail. From Monday to Thursday, the Line S2 runs only three daily trains from the city center to Yanqing, all of which stop at Badaling, while only two return trains stop at Badaling. From Friday to Sunday, there are usually seven trains from the city center to Yanqing, and six trains return pass through Badaling. The train is only allowed to use transit cards including T-Union cards or purchase a ticket at the station, and advance reservations are not accepted. If the train is overcrowded, passengers who cannot board the train will not be allowed to board the train.

The high-speed railway to and from Badaling leaves and arrives from Qinghe Railway Station, which is connected to Urban Railway Line 13 or Changping Line. It usually requires booking tickets in advance to get them, although tickets can be purchased at the station as it is generally busier, it does not work with any transport cards and can be booked up to two weeks in advance by CR website or app, but if the itinerary changes or the trip is cancelled, there is an additional fee for changing the ticket.

The line connecting Beijing Capital International Airport to the city center was opened in 2008, covering a distance of 30 km, with a maximum speed of 110 km/h. It only stops at three stations except the airport. The whole journey takes about 26 minutes, and provides about 90 trains a day, with an interval of about 9-15 minutes.

The other is the intercity railway operated by China National Railway connecting Beijing West Railway Station and Xiongan New Area or Tianjin, passing through Beijing Daxing International Airport on the way.  The distance between Beijingxi (West) Railway Station and the airport is 47 km, and the top speed is 160 km/h in this section.  There are two kinds of trains: local and express.  The whole journey takes about 28 minutes or about 34 minutes, 17-19 trainss are provided each day, all of them are reserved seats, and require real name authentication, passengers all need to use passports to purchase tickets in advance, ordinary transportation cards can not be used, the train has second class seats, first class seats and business seats.  Fares are 30 yuan, 48 yuan and 90 yuan respectively, but usually (in February 2024) offer a discount of 10-43%, and the second-class fare starts at as low as 17 yuan.  This line is less frequent, but for passengers with more luggage who need to travel to Beijingxi Railway Station to take other trains, they can transfer without leaving the station after arriving at Beijingxi Railway Station. You will find the Daxing airport train station located at -2 floor. The station is connected to the main terminal area by escalators.

The newer Beijing Daxing Airport is located 67km away from Beijing Capital Airport. You can reach Beijing Capital Airport in approximately 90 minutes travelling by car or taxi, depending on the traffic conditions, and the taxi ride will cost you about RMB 250 (€32 / $35.2).

The most convenient way to travel between Beijing and Tianjin city center is through the Beijing-Tianjin Intercity high-speed Railway, the trains departure every 5 to 15 minutes from 6 a.m. to 22:30 p.m., there are different kinds of trains, some trains stop halfway, some trains are direct, and some trains go further to the new city area of Tianjin. However, all trains stop at the center of Tianjin, and the travel time between Beijing and the center of Tianjin is about 30-40 minutes. Trains will also run until the mid night on some public holidays. The number of trains from central Beijing (Beijingnan Railway Station) to and from central Tianjin (Tianjin Railway Station or Tianjinxi Railway Station) all start with the letter C and followed by a four-digit number with the first digit 2, and cost 54.5 yuan, regardless of whether the train stops on the way. If you find that there are some G class trains between Beijingnan Railway Station and Tianjinxi Railway Station, they are running on the Beijing-Shanghai high-speed railway, rather than the Beijing-Tianjin Intercity railway, but if you buy their tickets, it does not matter, it will also arrive at the destination within the same 30-40 minutes, but they implement floating fares. Ticket prices may vary between 50 and 67 yuan.

All trains have reserved seats, even on busy days such as public holidays. These trains need to purchase tickets in advance through CR website or app, tickets usually start selling two weeks in advance, but if the itinerary changes and you need to change the travel time or cancel the travel plan, you will be charged a certain fee, details can be view related contents in the page of how to taking the national rail. The train service on this line have always very busy since the service began in 2008, and during some busy periods, tickets are often sold out a few days in advance, if you are sure of your journey, we still recommend booking tickets a few days in advance, otherwise you can only select tickets that are still available and not necessarily the one you want.

The trains running on this line are basically the same, they are CR400BF or CR400BF-G which start provide service between 2017 and 2020, there are many batches of them, but their seats and main in-car facilities are exactly the same, only a few details will be different. The maximum speed of trains on this line is 350 km/h but only for eight-car trains non-during peak hours, the maximum speed is 310 km/h for 16-car trains because the route design did not take into account such a large passenger flow as the the power supply facilities cannot meet the demand. All trains are at 310 km/h during peak hours on account of most trains are in 16-cars.  Even so, the difference travel elapsed time of them between downtown Beijing and downtown Tianjin is only three minutes.

Their are another four railways including the Beijing-Shanghai Railway, the Beijing-Shanghai high-speed Railway, the cross-line train services on Beijing-Tangshan and Chengde-Tianjin high-speed railway, and the cross-line train services on Beijing-XiongAn and Daxing-Tianjin railway. Among them, the first two railway lines are very frequent, but they mainly serve long-distance travel, providing only limited service between Beijing and Tianjin, and the second two railway lines are very frequent, only two daily services.

The Beijing-Shanghai railway mainly runs some long-distance sleeper trains, but they have some relatively cheap fares, if it is a traditional train composed of locomotives and carriages, their lowest ticket price is only 19.5 to 23.5 yuan for ordinary seats, while the second-class seat of EMU trains is about 42 to 46 yuan, on weekdays, a discount of 15-20% will be offered eccept public holidays. The specific fare depends on which station to board and drop off from, there are trains between Beijing and Tianjinxi Railway Station, Beijing and Tianjin Railway Station, Beijing Fengtai Railway Station and Tianjin Railway Station. Most trains on the Beijing-Shanghai high-speed railway stop at the slightly remote Tianjin South Railway Station in Tianjin, which also takes about 30 to 40 minutes, and they carry a floating fare, which can be between 50 and 67 yuan for second-class seats.

The cross-line trains on Beijing-Tangshan and Chengde-Tianjin Railways currently offers only two trains a day between Beijing station and Beichen station in the east of Tianjin.
