In July 2025, train dynamic testing began on Xinyi eastern extension, which is known as the most difficult construction project in the history of the MRT. This was an important milestone prior to the opening for operations. On July 18, Mayor Chiang Wan-an invited elected representatives and other distinguished guests to board the train together from Xiangshan Station to Guangci/Fengtian Temple Station. In addition to recognizing the MRT team involved in the project, Mayor Chiang assured residents of the construction safety and quality, and expressed optimism about the traffic benefits that will soon be realized with the opening of this section.

Mayor Chiang stated that although Xinyi eastern extension only consists of a single station and runs a length of just 1.4 km, linking with the following three major transportation corridors: Xinyi, Nangang, and Neihu will dramatically reduce travel times and boost the city’s competitiveness.

During the inspection, Mayor Chiang pointed out that although Xinyi eastern extension is only a 1.4-kilometer addition to the line, the scope of construction and degree of difficulty in designing it should not be underestimated. The excavation depth of Guangci/Fengtian Temple Station, which is the terminal station, reached nearly ten floors underground, and its structure was twice the size of a standard high-capacity station. Furthermore, the geological conditions varied from shallow muddy soft soil to deep bedrock, making it one of the most challenging construction projects in MRT history.

Mayor Chiang also mentioned that despite facing engineering difficulties and geological challenges on the construction of this section, the MRT construction team still worked diligently to overcome the difficulties. Having completed 87.12% of the project, they are now entering the final countdown stage. Following the completion of construction, it will become a new engine of east-to-west transportation in Taipei and satisfy the expectations for convenient transportation among residents living along the route.

DORTS stated that Xinyi eastern extension continues eastbound from the tail track at Xiangshan Station on the Xinyi line. It travels along Section 6, Xinyi Rd to Fude St in front of Guangci Charity Park and includes an additional crossover as well as the terminal station Guangci/Fengtian Temple. Moreover, the tail track runs east from the terminal station along Fude St, to Zhongpo South Rd and Yucheng Park. To date, the main tunnel and station structure have been completed, and the tracks have been completely laid. Station renovations and public art installations are currently underway. 

DORTS Systemwide Electrical & Mechanical Project Office (SEMPO), which is responsible for electromechanical engineering, further elaborated that the electromechanical equipment at Guangci/ Fengtian Temple Station, such as tracks turnouts, radio systems, high-voltage cables, and platform doors have been completely installed. The full-height platform screen doors have also been installed, and door opening and closing pressure verification testing will soon be carried out followed by train dynamic testing. It will be integrated into the existing Tamsui-Xinyi line system, and every effort will be made to open the line for operations in the first quarter of next year. 

SEMPO emphasized that they will continue to cooperate with Taipei Rapid Transit Corporation (TRTC) to schedule and conduct all testing during non-operational hours in the early morning in accordance with the principle of not impacting the operations of currently existing trains. In addition, they will also spare no efforts in ensuring construction safety and quality while also minimizing impacts on the surrounding traffic and residents' daily lives during the construction period.

DORTS stated that Xinyi eastern extension will inject new momentum into the future development of Taipei MRT and drive travel and business connections between the administrative center, the Xinyi District and Neihu Technology Park. Furthermore, DORTS anticipates that Xinyi eastern extension will enable citizens to enjoy a more comfortable, safer, and more time-efficient public transportation experience.
