Taipei Mass Rapid Transit System, Xinzhuang Line

Taipei MRT Xinzhuang

TYLin provided civil engineering services for the Xinzhuang Line project, Design Lot dk195, in Taipei City, Taiwan.

Taipei Mass Rapid Transit System's Xinzhuang Line is a high-capacity underground extension of the Zhonghe Line and Taipei’s first metro line to cross under the Tamsui River.

At 19.7 kilometers long, the line runs from Guting through transfer stations on the Nangang and Tamshui Lines and terminates in Xinzhuang. The line includes 16 underground stations and one maintenance depot.

TYLin’s scope of work included three underground cut-and-cover stations: the Xinzhuang (O2) station, Touchien Chuang (O3) station, and Hsiense Temple (O4) station, and associated bored tunnels.

TYLin provided civil engineering services for the stations, utilities design, environmental control, elevator and escalator planning and design, electrical and mechanical engineering, and technical services.

Project Highlights:

  • The underground stations are connected by two 3.4-kilometer-long single-track parallel bored tunnels, with nine cross passages placed between the parallel tunnels.
  • The 4000-square-meter transfer facility, with a two-story parking lot, is located near entrance A of the O3 station.
  • A 141-meter-long crossover section is located west of O2 station.
  • An L-shaped pedestrian underpass is connected to entrance A of the O3 station at the junction of S-Yuan Road and Zhong Zheng Road.
  • Light structures and transparent architectural design concepts were adopted for the station entrances, reflecting the local characteristics and chosen public art themes.
  • Precast concrete segmental lining was used for the bored tunnels, except at the junction of the bored tunnels and cross passages where steel segmental lining was used.
