On December 1, the first urban C-type train in China developed and produced by CRRC Changchun Co., Ltd. was officially released in Changchun. The train realizes the organic combination of high-speed rail technology and urban rail transit operation mode, with a maximum running speed of 160 kilometers per hour, with the characteristics of intelligent and advanced, safe and comfortable, public transportation operation, and high appearance, and has broad application prospects in the national urban railway project. It is reported that in the future, the train will be the first to be used in the Shanghai Rail Transit Municipal Airport Liaison Line Project.
Wang Yanfei, the train project design manager, introduced the 4 highlights of the C-type train in the city, and let's take a look at what is worth paying attention to in this train!
Highlight 1: Intelligent and advanced
Intelligent driving. For the first time in the field of domestic urban trains, the train realizes the functions of automatic turnback, automatic station reporting and linkage with the platform screen door in the CTCS2+ATO mode.
Smart services. The train is equipped with functions such as intelligent light adjustment, intelligent pressure wave adjustment, wireless charging, and intelligent calculation of the number of passengers, providing intimate services for passengers.
Intelligent monitoring. The train monitors key indicators including the running section, pantograph net, and vehicle running performance, and ensures the safety of operation through track monitoring, active obstacle detection and other technologies.
Intelligent O&M. Train application fault** and health management system (PHM), using big data technology to escort trains.
Highlight 2: Bus-based operation
Flexible grouping. The train can realize a variety of operation modes such as 4-car marshalling, 4+4 reconnection marshalling and fixed 8-car marshalling, and for the first time in China, the length design of vehicles such as the first car and the intermediate car is adopted, so that a variety of operation modes can run in parallel.
Large passenger capacity. The maximum capacity of the 4-car train is 1016 people, and the maximum capacity of the 8-car train is 2180 people, in order to meet the needs of public transportation operation, the carrying capacity of the car body meets 8 people per square meter.
Highlight 3: Safe and comfortable
High level of security. The train meets the 25km h collision safety requirements, and the car body structure follows the Fuxing EMU technology platform, which meets the strength standard of high-speed EMUs and meets the fatigue load strength of 10 million times. The bogie is based on the Fuxing EMU technology platform, which has the characteristics of advanced, mature, safe and reliable.
The comfort level is excellent. The train is based on the high-speed rail technology platform, and the stability and comfort indicators have reached the excellent level. The noise in the car is less than 72b(a) during operation, which is better than the industry standard, and the air tightness of the whole vehicle is stronger, and the time from 2600Pa to 1000Pa is greater than 40 seconds, which can keep the air pressure in the car stable and bring a comfortable riding experience to passengers.
New types of evacuation. The train innovates the evacuation mode of rail passenger cars, with a folding evacuation ladder and multi-step step treads under the train, so that passengers can be transferred from the floor of the passenger compartment to the trackside evacuation platform through the steps.
Highlight 4: Good looks
The theme of the train design is "The Dream of Shanghai", and the design scheme incorporates Shanghai's characteristic elements, and the vehicle adopts a blue flexible curve appearance with gold embellishments, like a bend of river water passing through the city, showing the characteristics of Shanghai. The front of the car is designed with a large streamlined silhouette and diamond-shaped headlights, like a radiant dragon rising across the river, highlighting the vitality of the city.
The train is decorated in a fresh blue color that echoes the inside and outside, and is laid out on the seats and floor, giving a quiet and soothing riding environment. The colorful strip light design at the top gives passengers a sense of flow through the city, with gradient lights on both sides and the characteristic lights of the luggage cabinet, which sets off a strong sense of science and technology. Some of the interior of the vehicle adopts a color-block design to increase the visual level of the vehicle and enhance the riding experience of passengers.
