Chengdu Metro Line 13 Phase 1 will use 8A formation train with a top speed of 140 km/h,making it the first city-wide fully automated train in China with a speed of 140 km/h.The train is 186 meters long,with a passenger capacity of 2164 and a maximum capacity of 3054,and it has high intelligence,high comfort,and high safety features to enhance passengers'travel experiences.

Monitoring devices,such as pantograph intelligent monitoring device,track inspection intelligent monitoring device,running gear intelligent monitoring equipment,and battery intelligent monitoring devices.Video surveillance equipment is installed at the pantograph position,which can monitor the vehicle's status in real-time,helping maintenance personnel to analyze and troubleshoot faults more accurately and efficiently.In addition,the train's passenger information system uses industry-leading image recognition technology,which can detect abandoned items and analyze car occupancy,achieving real-time transmission of detection and analysis results.

The train has implemented multiple sound insulation and noise reduction measures that effectively reduces noise during operation.For example,double layer aluminum alloy car body,phenolic resin floor with excellent sound insulation,airtight plugs doors with auxiliary locking devices,double-layer windows filled with argon gas,and nano-absorbing materials filled in the top and side walls of the car body's cavity,as well as the optimized air conditioning return air structure.The design of the entire vehicle focuses on details,enhancing hardware performance,optimizing structural design,and minimizing in-car noise,further improving passengers'riding comfort.

The train is designed with streamlined engineering,which comprehensively improves aerodynamic performance,reduces wind resistance,and uses lightweight aluminum alloy materials for the body,air conditioning unit,and equipment box cover,reducing vehicle's weight to achieve energy-saving and emission reduction purposes.The train's air conditioning system uses frequency conversion technology,which further improves energy efficiency and saves electricity.At the same time,the passenger compartment illuminating lamp is upgraded to automatic brightness-adjustable LED lighting,which can adjust the brightness automatically based on the contrast between the natural light outside the car and the brightness inside the car,further reducing lighting energy consumption.

In terms of temperature control,the train's air conditioning system uses frequency conversion compressors and fans,and is equipped with an air quality monitoring module,which can adjust the ventilation accurately according to the CO2 concentration and passenger capacity changes in the car.In terms of hardware equipment,the passenger compartment is equipped with a 43-inch electronic map navigation screen,a 28-inch LCD display,a 27-inch electronic display,fully meet the needs of passenger information viewing in the train;and based on ergonomics,the passenger compartment seat structure has been redesigned to optimize the back curve of the seat,providing passengers with a more comfortable environment.

The entire train is designed according to the highest level of fully automated driving,GOA4.The train is equipped with a high-voltage system control platform for fully automatic driving,which can diagnose,reset,or isolate faulty components intelligently,and better adapt to the conditions of fully automated operation.In addition,the train's head is equipped with passive obstacle detection and derailment detection devices.When the train detects obstacles on the track or is in danger of derailment,it will trigger an emergency brake to ensure the safety of train operation.

After the opening of Chengdu Metro Line 13 Phase 1,it will strengthen the connection between Longquanyi District and the city center and transfer to other lines within the urban area,connecting scenic spots such as DuFu Thatched Cottage,Qingyang Palace,Xingfu Meilin,and San Sheng Flower Village,as well as universities such as Sichuan University(Huaxi Campus)and Sichuan Normal University(Lion Mountain Campus),effectively improving the accessibility of the regional rail transit network.Currently,16 out of 21 stations of Line 13 Phase 1 have been capped,and the structures of the other 5 stations are under construction.The tunneling design total amount of the shield machine has reached 77.9%,and the first train of Line 13 has completed static and dynamic commissioning.All preparation work is advancing rapidly.In the future,Chengdu Rail Transit Group will closely focus on the safety of fully automated driving,high-quality characteristic services and other aspects based on Line 13 Phase 1's route and passenger flow characteristics,and efficiently and high-quality promote the preparation work for new lines.(Du Can)
