The station building has two main levels, for suburban traffic as well as three connecting and business levels. Compared to Raffles Place MRT station and Taipei main station, it is one of the most densely packed stations. The upper track consists of six tracks on four bridge structures. The two outside lanes are single track and four others inside are double track. In between, the three platforms at the height of ten metres are arranged. On the lower track level are four platforms of which eight tracks along the north south line, at a depth of 15 metres. This is followed by the eastern end of another platform with two tracks for U55, similar to the Timothy station on the Frankfurt U-Bahn. To the east of the underground station, a similar double track platform is also being built as part of the S21 project.
