The 6-car formation for Beijing Subway Line 13 is divided into 3 traction units, each consisting of 1 motor car and 1 trailer car (form of formation: =MC*T*M*T*T1*MC=). The seating capacity of the train is 1,428 persons (1,820 persons when standing passengers are allowed).
Main technical features:
The vehicle features a weathering steel drum section. The height of the car is merely 3,700 mm in order to adapt to track conditions.
The thickness of the ceramic-sand floor is increased to 40 mm, the sound absorbing material is thickened, and wheel noise reduction technology is used to effectively reduce vehicle noise and vibration and improve ride comfort of passengers.
The car body adopts a welded integral load-carrying structure that features an underframe without center sill, and inside and outside frames of side doors and cross members of windows are designed with reinforcements so that car body strength is ensured and car body weight is reduced.
Passenger saloon interior finish featuring aluminum profile construction is used on a homemade car for the first time. This method is characterized in simple construction, good manufacturability, easy installation, and attractive and fashionable decoration effect. An air conditioning system is added to further improve comfort of passengers.
