Porto is the second largest city of Portugal. It has 6 metro lines with 81 stations, covering a total length of 67km, and serving Porto’s urban and suburban areas. On January 21, 2020, CRRC Tangshan and Metro do Porto signed a contract for Porto’s metro and maintenance, which became the first transaction of urban rail vehicles between China and EU countries. The new type of metro trains were jointly designed by CRRC Tangshan and Metro do Porto considering the operating environments and needs of metro in Porto. The train embodies design concepts of green, intelligence, comfort and safety, features lightweight, low energy consumption and intelligence, and is the new generation metro train that meets European standards.

CRRC Tangshan boasts rich vehicle maintenance experiences and an efficient intelligent operation and maintenance system. Its after-sales service team in Porto works closely with Metro do Porto, formulates a tailored maintenance plan based on the operational needs, and continues to provide strong support for the safe and reliable operation of the metro trains.
