[10] The main railway station serving Kaohsiung, formerly known as Takau (Chinese: 打狗) and Takao (高雄), was located at Hamasen.

The rebuilt station was designed to accommodate the proposed extension of Taiwan High Speed Rail.

Nevertheless, the railway in Kaohsiung only has the capacity of double-track, making it difficult to allow many[quantify] such shuttle trains as EMU800 for domestic transportation to run through at once.

A team from NSYSU examined air quality in Kaohsiung main station on early October 2019 and found that the PM2.5 was 17 times higher than that of standard, putting passengers and workers at risk of getting lung disease.

[17] Trains equipped with diesel engine that run through South-Link Line, the only single-track and non-electrified railway in Taiwan, were to blame.
