Green line (Taichung Metro)


The Green Line is a future rapid transit line in Taichung operated by the Taichung Metro. With its construction completed in 2016, it is currently in its testing phase, and is planned to open in 2020. Two extensions, one heading east and the other reaching south into Changhua, are also planned.

Route overview

The line currently under construction is known as the Wurih-Wunsin-Beitun Line. It begins in Beitun District at Beitun Main metro station and runs westward, crossing the TRA Taichung Line at Songzhu metro station. It then follows Wenxin Road, passing through Xitun and Nantun and forming a wide semicircle around the city center. At Daqing metro station, the line runs parallel to the Taichung Line until its western terminus at Taichung HSR Station in Wuri. The line is fully elevated except for small sections at each terminus.

Planned extensions

There are two planned extensions to the line. The first, known as the Dakeng Extension, branches east from Jioushe metro station and runs along Songzhu Roadto the base of Dakeng. The second, known as the Changhua Extension, runs west past Taichung HSR Station and crosses the Dadu River to Changhua. The extensions add two and five more stations respectively, and will cost an additional $25 billion NTD.

History

A metro system in Taichung was discussed since 1990, which would connect various suburbs including Caotun, Zhongxing New Village, and others. The plan was dropped due to high cost and low projected ridership. A new proposal was renewed and approved in 2004, but construction did not begin immediately because of costs exceeding estimates and disagreements over where stations would be.
In 2010, preliminary work began by relocating trees on the median and rerouting the utilities that run under those roads. Progress plagued with various delays, including conflicts between the city and electrical contractors, problems with land acquisition, and the bankruptcy of a major utilities contractor. Because of the delays, mayor Jason Hu and his administration were heavily criticized by rivaling political parties.
Formal construction began in May 2013. Two separate incidents occurred during construction. On 19 August 2014, a crane malfunctioned and broke off its arm, falling on top of a restaurant. No injuries were reported. Then, on 10 April 2015, a crane's arm snapped while lifting a 209-ton I-beam, causing the beam to fall and crushing a car underneath. Workers atop the beam were also thrown off. The driver of the car and three workers lost their lives, while four other works sustained heavy injuries. Construction was halted for three months following the incident. On 30 June 2016, construction of the line was completed, and testing began soon after.
Initially, the stations numbers were numbered sequentially from G1 to G20, with the "G" representing green. However, since G8 is pronounced similar to chi-bai, which is considered profane in Hokkien, the "G" prefix was changed to "1", which stands for the fact that the Green line is the first line constructed.

Rolling stock

The line will run eighteen EMU trains equipped with automatic train operation. The trains are powered by a direct current, 750 V third rail. Each train will have a capacity of roughly 536 people divided into two cars, each car having ten doors and two air conditioning units. Of the eighteen trains, nine are built by Kawasaki Heavy Industries in Kobe, Japan, while the remaining nine are built in Taiwan.

Station list

The Green Line will have a total of 25 stations, 18 of which are currently in construction. English names use Tongyong Pinyin, with exceptions.
