On March 2, the third section of Shanghai's first "underground railway" airport connection line was completed, becoming the first penetration section of the entire project.
According to the plan, the airport connection line is the first urban railway project in China that is compatible with the national railway design specifications and urban rail transit design standards. Within hours, two Harmony EMUs can travel side by side in the 16-meter shield tunnel.
