The Taipei Metro Dongmen Station is a planned transfer station on the Xinzhuang Line and Xinyi Line located beneath Xinyi Rd, Sec. 2 between Jinshan S. Rd. and Yongkang St. in Zhongzheng and Daan districts in Taipei, Taiwan.^[1] The station is scheduled to open in June 2012 with the opening of the Zhongxiao Xinsheng to Guting segment of the Xinzhuang Line.^[2]

Station overview

The station will be a four-level, underground station with island platforms for both the Xinyi and Xinzhuang Lines. The platforms will be stacked, allowing for cross-platform interchange between the two lines. The Xinyi Line station will be 187 m (614 ft) long and 25 m (82 ft) meters in wide, while the Xinzhuang Line station will be 217 m (712 ft) meters long and 24.7 m (81 ft) meters wide.^[3] It will have eight entrances/exits, one accessibility elevator, and two vent shafts.^[1]

Construction

The main diaphragm wall of the station is 1.5 m (4.9 ft) thick and 72 m (236 ft) meters deep, thus making it the deepest diaphragm wall of all Taipei Metro stations.^[3] Construction on this part started in March 2004 and was completed on April 26, 2007. It was announced that on July 15, 2010, the intersection of Jinshan South Road and Xinyi Road would be restored to its pre-construction state.^[4]

Five tunnels

Because the station will be the future intersection of the Xinyi and Xinzhuang Lines, five tunnels will intersect in a twisted form beneath the nearby Hangzhou South Road: two Xinyi Line tunnels, two Xinzhuang Line tunnels, and a common duct.^[5] They will be stacked and intersected underneath existing buildings and will run along Hangzhou South Rd., Sec. 2.^[6] Construction on the five tunnels began on September 15, 2005 with the start of construction on the Xinyi Line and was completed by January 17, 2009.^[6] Of the subway tunnels, the shallowest is the northbound Xinzhuang Line tunnel at 13.4 m (44 ft) meters deep, while the deepest is the Xinyi Line southbound tunnel at 25.3 m (83 ft) meters deep.^[6] The common duct, by far the shallowest of the five, is 7–8 m (23–26 ft) meters underground.

Station layout

The future layout of the station will include two stacked, island platforms.^[7]
