The special equipment of the subway line includes track equipment, including mainly steel track（operational steel track）, contact rail, sleeper, switch, roadbed and connecting parts, all of which together constitute the foundation of the operation of subway trains. 
All the operational steel rail for the operation of the subway is the 50kg/m and 60kg/m steel rail at the State-set standard. 60kg/m steel rail holds longer than the 50kg/m steel rail in terms of either its service life or its capability of withstanding wear and tear. Therefore, for Line13 and Line Ba-Tong, they adopt 60kg/m steel rail completely. For the operating lines, the seamless line with the standard 1,435m m gauge is used.  

Switch equipment is used for the operating line and the dispatch and railroad shift at the train garage. It includes single opening, cross shifting lines and compound crossing and division.  

The power supply system adopts the mode of providing direct current at voltage 750V and with contact rail（the third rail）receiving electricity. In other word, when the train runs, the contact rail has electricity in the entire operational process with the direct current at the voltage of 750V. The train collects electricity by touching the upper part of the third rail with its electrical brush so as to drive the train to move on The contact rail has a “工-shaped cross section and weighs 51. 36kg/m。

The roadbed and sleeper are the foundation of steel track. The roadbed is divided into two kinds: integrated roadbed and rubble roadbed. The sleeper is divided into wooden and concrete sleeper. For subway stations, underground lines and elevated lines, the short sleeper styled concrete integrated roadbed is adopted, while for on ground lines, the concrete sleeper and rubble roadbed. As the subway adopts a mode of providing electricity through the third rail, the concrete sleeper with the State-set standard cannot be used for the on-ground lines. Therefore, for the Fu-Ba depot of Line 1, wooden sleeper is used for the on-ground line. In 2000, Beijing Urban Construction Design Institute designed a special prestress concrete sleeper which are now used for the on-ground lines of Line13 and Line Ba-Tong.
