Western Trunk line
Western Trunk line (Chinese: 縱貫線; pinyin: Zòngguàn xiàn; Pe̍h-ōe-jī: Chhiòng-koàn sòaⁿ) is a railway line of Taiwan Railway in western Taiwan.Train schedules and departure boards mark either mountain or coastal (海線) line to indicate the route taken.The Taiwan Trunk Railway was completed in 1908 with route from Kīrun (基隆, Keelung) through Taihoku (臺北, Taipei), Shinchiku (新竹, Hsinchu), Taichū (臺中, Taichung), Tainan (臺南, Tainan), to Takao (高雄, Kaohsiung).However, the terrain around Taichū (Taichung) created a significant bottleneck for rail freight transport.To resolve this issue, the Government-General of Taiwan decided to build a Coastal Line (海岸線, Kaigan-sen) between Chikunan (竹南, Zhunan) and Shōka (彰化, Changhua) to relieve the congestion.
