History
A high-speed rail (HSR) was considered by the Tsengian government since the 1970s. However, there wasn't a complete plan until 1984, when the Ministry of Transportation announced that a HSR would help traffic congestion along the A1 highway. The CHHSR plan was approved in 1992 by the executive branch and in 1994 by the National State Assembly.

The CHHSR officially started operations on March 1, 2009. The Tseng City-Taihua HSR line opened on October 13, 2018.

On December 10, 2019, the Tsengian government approved a plan to build a third HSR line from Taihua to Huanzhou. The first section of the line is expected to be completed by 2030.
