Models

First Generation

In the 1960s to mid-1970s, the Beijing Subway used DK2 and DK3 models made in Changchun. The DK stands for diandong keche or electrically-operated passenger car. These models and their derivatives, the DK3G, DK20, DK16A, BD1 and BD2 are classified by the Beijing Subway as the first generation. 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. The refurbished DK16AG trains entered into service on Line 2 in 2005.

Second Generation

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. The M-series trains that appeared on Lines 2 and 13 were made by Japan's Tokyu Car Corporation.

Third Generation

In 1998, the subway began deploying a new generation of train sets that featured variable voltage variable frequency control mechanisms. These models include the DKZ4, DKZ5, and the DKZ6. DKZ stands for diandong keche zu or electric passenger train sets. The Changchun RVC also made 174 DK28-DK31 metro cars, which uses VVVF inverters and AC motors for Line 1, and 136 DK32-34 trains for Line 13. In 2005, Line Batong began using SFX01 and SFX02 trains made by Qingdao Sifang.
