The Indies-style station building was designed by Ir. Louis Cornelis Lambertus Willem Sloth-Blaauboer. This station is classified as a side station; extends along the axis of the railroad track. The shape of the building mass is a combination of cubes and beams, and the roof is in the form of a rectangular pyramid in the main lobby and triangular prisms on both sides. The roof of the lobby building is crowned with a dome so that it gives the impression of being majestic, firm and solid which is characteristic of Indian architecture. The roof of the main station building which is the main focus of this station is made of tile, while the canopy of the station platform uses a tin roof supported by steel pillars. The wall thickness of the station is 30 cm and the supports are thickened 50 cm to strengthen the construction. The doors and windows are ornamented in the form of
rolaag brick construction, which is connected with ornate ceramic glazing, giving the building an artistic impression. Semarang Tawang Station initially had five train lines with track 4 being a straight line. After the
double track to
Alastua Station was officially operational on 5 December 2013 and to
Semarang Poncol Station on 7 February 2014, the number of lines increased to eight and line 5 was also used as a straight line. Lines 1 and 2 are used as intercity train stop lines for boarding and dropping passengers, line 3 is used as the arrival and departure points for intercity trains that start their journey from this station and is used for parking a series of trains, line 6 is used as a place for crossing and following trains, and lines 7 and 8 are also used as a parking lot for the train series as well as a washing place for the train series. At the eastern end of lines 6 and 7—close to Jalan Ronggowarsito—there is a place for loading and unloading
containers. Even though this station is a large station, this station still uses a low-sized platform, while a high-sized platform is only available on line 1 which is used to make it easier for passengers to get on and off and accommodate passengers with disabilities. In 2019, the track layout at the station underwent a minor overhaul and the old electrical signaling system has been replaced with the latest one by Len Industri. == Services ==
