T.Y. Lin International (TYLI Taiwan) provided civil engineering services for the Muzha Line in Taipei. Taipei’s first metro line, the Muzha Line is approximately 11 kilometers long, with 12 stations.
The Muzha Line now forms part of the larger Wenshan Line. A medium-capacity line connecting Taipei Zoo and Zhongshan Junior High School, the line is elevated except for an 810-meter section that comprises a new Austrian Tunnel Method (NATM) tunnel. The system operates with four-car rolling stock and is driverless and fully automated. The Muzha Line was rebranded as part of the larger Wenshan Line in 2008.
- The line has a vertical clearance of 5-7 meters and span lengths that range from 25-75 meters.
- Precast concrete box girders were used for shorter spans, with steel box girders used for longer spans. All box girders were prefabricated and transported by truck to the site for assembly and installation.
- Elevated stations are two-level steel structures supported by single columns founded in the street median. Station length is 80 meters. Width varies from 20-30 meters, and station height is 15-17 meters above the street level.
- Entrance buildings are typical, two-story reinforced concrete structures.
- Architecture for the station exteriors is made of curtain wall finishes.
- The operation and maintenance depot contains the control center, workshops, maintenance shops, storage buildings, public parking, test track, and other service-related structures..
TYLI Taiwan provided civil engineering for the stations, utilities design, environmental control, and elevator and escalator planning and design.
