The Taipei Metro Xindian Line is an underground high-capacity line. The 11.2 km (7.0 mi)-route has 10 stations (including the partially elevated Xiaobitan Branch Line) and is part of the Green Line. The line runs under the Roosevelt Road, following the route of the former TRA Xindian Line—which ceased service in 1965— on its southern section. It serves the areas of Xindian, Jingmei, Gongguan, and Ximen.
