Zhonghe–Xinlu line

The Zhonghe–Xinlu or Orange line is a line of the Taipei Metro named after the districts it connects: Zhonghe, Xinzhuang and Luzhou. As of 29 June 2013, all construction on the Line O has been completed. The line runs through New Taipei and Taipei and has a terminus in Taoyuan City.

Due to heavy traffic for residents in the districts of Luzhou and Sanchong traveling in and out of downtown Taipei, a rapid transit line was constructed to meet this urgent need. Although the Luzhou Line is technically only the section from Daqiaotou to Luzhou, the Xinzhuang Line section is commonly included as part of the Luzhou Line. All stations are equipped with platform screen doors and it is the first high-capacity line in the system equipped with them.
