The vehicle consists of four carriages, which can accommodate 334 passengers (including 64 seats) and has a maximum running speed of 80 kilometers per hour. The new train currently serves six existing lines in Porto. It is the first time that CRRC has been exported to Europe and EU countries. Adhering to the design concept of "safety, comfort, green, intelligence, humanity, fashion and elegance", CRRC has built a rail vehicle with unique industrial beauty.This vehicle has successfully obtained the third-party independent safety assessment (ISA) certificate of Italian Classification Society (RINA), which is the first time that CRRC has obtained the safety assessment certification of urban rail vehicles in EU countries.In the styling design of the front of this scheme, the curved headlight design fully draws lessons from the design of the landmark building "Louis I" bridge in Porto, and creates a penetrating headlight design, which symbolizes the mission that the bridge connects all parts of Porto and CRRC to "connect the world and benefit mankind". At the same time, the continuous curved headlight styling of the front constitutes a smiling face, which symbolizes the beautiful meaning of welcoming guests from all directions, and shows the profound heritage of China manufacturing and China culture as well as the local city of Porto.The overall vehicle color scheme is designed with low saturation metallic paint color, and the yellow ribbon on the front of the vehicle is designed with a film pasting scheme with night vision function, so as to improve the recognition of the vehicle when driving on the highway, optimize the driving guarantee under the shared right of way, make the vehicle more dynamic and fashionable, and make the Porto tram that shuttles through the city and exports to Portugal truly become a landscape of the city.
