AllBeijing Subway trains run on1,435 mm (4 ft 8+1⁄2 in)standard gauge rail and draw power from the750 V DC third rail, except those on Lines 6, 11 14, 16, 17 and 19, which use1,500 V DCoverhead wires.^[1] Lines 6, 15, Fangshan, and Changping lines have a designed maximum service speed of 100 km/h (62 mph).^[2] The Airport Line is linear motor driven with a designed maximum service speed of 110 km/h (68 mph)^[3][4] All other Lines have a maximum service speed of 80 km/h (50 mph). Currently, Lines 1, 2, 4, 5, 8, 9, 10, 13, 15, Batong, Daxing, Changping, Fangshan, Yanfang, and Yizhuang lines use 6 car B size trains. Initially, the Batong line and Line 13 was originally used 4 car trains and now expanded into six.^[5][6][7]

The most common rolling stock of the Beijing Subway is the Type-B car, which has a carrying capacity of 245 passengers per car and top speed of 80 km/h (50 mph), drawing750 V DC power from thethird rail.^[8] Most lines operate the six-car Type-B train set that can carry 1,460 passengers per train and transport 43,800 passengers per hour.^[8] Lines 6 and 7 use eight-car Type-B train sets that can carry 1,960 passengers per train and 58,800 passengers per hour.^[8] The Type-B trains sets of Lines 6 and 7 can draw1,500 V DC power and can reach 100 km/h (62 mph). TheYanfang Line operates four-car Type-B train sets with”driverless” automatic train operation.

Type-A cars run on Lines 11, 14, 16, 17, 19 and under construction Lines 3 and 12. They are 3.1 meters longer, and 20 cm wider than Type-B cars with a designed capacity of 310 passengers per car and 10 sets of doors per train compared to 8 sets of doors per train on Type-B cars.^[9][8] Type A cars draw1,500 V DC power from overhead wire and can reach 100 km/h (62 mph). Line 14 uses six-car Type A train sets which can carry 1,860 passengers per train and allow for throughput of up to 55,800passengers per hour per direction. Lines 16, 17 and 19 uses eight-car Type-A train sets which can carry 2,480 passengers per train and allow for throughput of up 74,400passengers per hour per direction.^[8]

TheCapital Airport Express has its distinct 4-carlinear motor train sets, powered by750 V DC electricity via the third rail, and can reach a maximum speed of 110 km/h (68 mph).^[10][11] The under constructionLine 28 will also use L type trains but 6 cars long.

TheDaxing Airport Express uses Type-D train sets with top operational speed of 160 km/h (99 mph).^[12][13] These trains are powered by25 kV 50 Hz AC overhead wires. The eight-car train sets have seven passenger cars and one car to carry luggage.^[13] The under constructionLine 22 will also use eight-car Type-D trains.

TheS1 Line'smaglev trains feature six-car train sets that run on1,500 V DC power and can reach 100 km/h (62 mph).^[14] Compared to subway trains that run on conventional track, the maglev train has a smaller minimum turning radius of 75 meters compared to 200 meters, can climb steeper slope of 53‰ versus 40‰ and emits less noise.^[15] The six-car train set can carry 1,032 passengers.^[15]

TheXijiaoLRT andYizhuang Tram Line T1 operates five-car trams that draw750 V DC from overhead lines and can reach 70 km/h (43 mph).

From the subway's inception to 2003, all Beijing subway trains were manufactured byCNR Changchun Railway Vehicles Co. Ltd. All rolling stock on Lines 2, 5, 6,^[16] 9, 10, 13, 15, Yizhuang line, Capital Airport Express and some of Line 1, 14, 16, and Yanfang line stocks^[3][17][18] are produced by CNR Changchun.^[19] However,CSR Qingdao Sifang Co., Ltd. has recently produced rolling stock for the Beijing subway. CSR Sifang produced all the trains for Lines 4,^[20][21] 8,Daxing,^[21]Changping,^[22] Daxing Airport Express and some of Line 1,^[23] 14,^[17][24][25] 16, and Yanfang line.

TheBeijing Subway Rolling Stock Equipment Co. Ltd., a wholly owned subsidiary of theBeijing Mass Transit Railway Operation Corp., provides local assemblage, maintenance and repair services. It has also made trains for line 7, Batong, and Fangshan lines.

In the 1960s to mid-1970s, the Beijing Subway used DK2 and DK3 models made in Changchun. TheDK stands fordiandong keche or electrically-operated passenger car.^[26] These models and their derivatives, the DK3G, DK20, DK16A, BD1 and BD2 are classified by the Beijing Subway as the first generation.^[27] In recent decades, the Beijing Subway Rolling Stock Equipment Co. refurbished the DK16A and DK20 models, which remained in use well into the first decade of the 21st century.^[28] The refurbished DK16AG trains entered into service on Line 2 in 2005.^[29]

From the 1980 to the early 1990s, the subway introduced several new models including the DK6, DK9 and their derivatives the DK11, DK16 and GTO.^[30] The M-series trains that appeared on Lines 2 and 13 were made by Japan'sTokyu Car Corporation.^[31][32][33]

In 1998, the subway began deploying a new generation of train sets that featuredvariable voltage variable frequency (VVVF) control mechanisms. These models include the DKZ4, DKZ5, and the DKZ6.^[34]DKZ stands fordiandong keche zu or electric passenger train sets.^[26] CNR Changchun also made 174 DK28-DK31 metro cars, which uses VVVF inverters and AC motors for Line 1,^[35] and 136 DK32-34 trains for Line 13.^[36] In 2005, the Batong line began using SFX01 and SFX02 trains made by CSR Qingdao Sifang.^[26]The 40 trains of the Airport Express were made by a joint-venture between CRRC Changchun andBombardier Transportation, and uses Bombardier'sInnovia Advanced Rapid Transit (ART) 200 technology.^[33][37]

Since 2017, trains have been ordered with capabilities for unattendedautomatic train operation. Starting with the DKZ70 and SFM16 trains on the Yanfang Line. Since then trains on theDaxing Airport Express, Lines 11, 17 and 19 operate or are capable of operating in GoA4 unattended train operation mode.
