The station serves as a major node on the Southern Railway, which links it to Vienna in the north, and Slovenia in the south.

In 2001 the station was modernised and partly rebuilt to incorporate escalators to the platforms and also a small shopping mall.

Since 2010 the station has been adapted for its new role as an international transport hub and to cope with increasing national and regional traffic.

When the construction of the Koralm Railway is completed all international traffic from Vienna to Italy will pass through Graz.

One of the two pedestrian tunnels to the platforms has been extended to the Wagner Biro Straße giving access to the station from the west as well.
