The Taipei Metro Zhonghe Line is a high-capacity, underground line and is part of the Orange Line. The 5.4 km route has 5 stations and runs from Nanshijiao and passes beneath the Xindian River into Taipei and terminates on the Xindian Line at Guting.^[1] The Zhonghe Line is unique among Taipei Metro lines in that a melody similar to that used on the Tokyo Metro Namboku Line is used as a doors closing signal, and most stations feature a stacked side platform configuration.

History

On June 1992, the construction of Zhonghe Line began. It was the most difficult and arduous one among all lines of Taipei metro. The tunnels running through Zhonghe-Yonghe area had to pass under narrow streets, skyscrapers and crowded blocks, with limited spaces for underground station above ground. As a result, the whole neighborhood traffic had its so-called "Dark Ages" when the Cut-and-cover method was used for station platforms, concourses and crossovers during the 1990s. Besides the river-crossing section, the work suffered from biogas below the waterfront. After the construction, Zhonghe Line became more costly than all the other lines, 6,249 million NT dollars per kilometer.^[2]

Since the line opened for service on December 24, 1998,^[1] it has been the most important access to downtown Taipei for nearly half a million of commuters who live in the district.

Rolling stock

Over the years, three versions of rolling stock were used on this line, as well as on the through services between Nanshijiao and Beitou. Originally, the line used a large fleet of C301 train sets. In 1999, only a few C341 train sets were used. In 2007, some C371 train sets were introduced. Today, the entire fleet used on this line is the C371 train sets after the original C301 train sets were confined to the Tamsui and Xindian Lines upon the opening of Dongmen Station on September 30, 2012.

Completion of the Orange Line

With the completion of the Luzhou Line and a part of the Xinzhuang Line in 2010, as well as the opening of Dongmen Station in 2012, trains now connect through to the Luzhou Line or Xinzhuang Line instead of the Tamsui Line or the Xindian Line at Guting. This means that trains will travel from Nanshijiao to either Luzhou or Huilong respectively.
