 Since the corridor of the originally proposed Red Line is partially served by the TRA mass transit construction, the Blue Line corridor was chosen as a first step to implement BRT in Taichung.Construction of the first line, the Green Line, had been paid for and was expected to begin in October 2007, though it was pushed back and started construction on 8 October 2009.The section of the Green Line is now scheduled for completion by 2020 and will include 18 stations.
