1、Green and Economic As a rail transit form between EMU and urban rail, city EMUs have the characteristics of intensive and efficient, moderate cost and flexible operation organization in the process of new urbanization development, providing high-quality alternative solutions for traffic problems in large and medium-sized cities. The rigid catenary pantograph with the highest operating speed in the world. It can meet the requirements of pantograph-catenary matching in the whole tunnel operation, save the civil engineering cost, and has high popularization value. The power performance not only meets the performance requirements of high acceleration (≥0.53m/s2) and large electric braking, but also makes the power configuration have better redundancy and fault operation ability, thereby realizing the quick start and stop of vehicles, reducing travel time and improving operational efficiency. 2、Pioneering design of highly intelligent and intelligent train The world's first high-speed urban EMU platform with rigid catenary in all tunnels. The layout of passenger interface based on the principle of hollow tube allows the layout of the whole passenger area to be spacious. We vehicle intelligent management center, and applied the latest self-sensing technology, algorithm and intelligent model to predict, diagnose, monitor and manage the status of vehicles, becoming the first EMU in China to realize predictive maintenance, remote diagnosis and full life cycle management. The birth of the world's first bogie using bogie-frame fatigue life prediction technology and the application of infrared ray monitored pantograph-catenary monitoring system and traction braking intelligent components have changed the safety of trains from passive safety to active safety. 3、Appearance with great tension and Humanized interior design The appearance is unique and adopt the inspiration of "flying wing", which reflects the extreme sense of speed. The interior design is modern, simple and full of design details. Shape of seat end plate and glass screen echoes the LOGO " cavel " shape of Guangzhou Metro, which not only shows the exclusive elements of Guangzhou Metro, but also conveys a sense of tolerance and security for passengers. We highlight design of passenger interface, and use the long black mirror electronic logo on the side roof plate to improve the sense of science and technology, the beauty of the interior of the passenger room, and reduce the sticking for the logo.
