Therefore, the start date for operation was delayed gradually, and on January 15, 2007, at last, operation started provisionally between Banqiao Station (Taipei County) and Zuoying, with operation in the entire line starting officially in March of 2007.
このため、開業時期が徐々に遅れ、結局2007年1月5日に板橋駅(台北県)-左営間で仮開業し、全線は2007年3月に正式開業。
