  ## History
  
  The planning of network of rapid transit in Taichung was initially started in 1990s. A prototype of rapid transit line running on Taiwan Boulevard (then known as Zhonggang Road) was first proposed in 1998, along with the current Green line and a third Red line, but never progressed past the planning stage.
  
  During his term in office, Lin continued to advocate for a rapid transit line along the route. In October 2018, the Executive Yuan approved the feasibility study submitted by the Taichung City Government. In 2019, the line embarked on its overall planning phase with an estimated cost of $128.56 billion NTD.
