All levels are linked via escalators and stairways, while elevators are additionally provided between the concourse level and the platform level.
The station contains only one island platform for two tracks of opposite directions, with floor-to-ceiling platform screen doors sealing the platform from the tracks.

The station has two access points from street level, of which one is larger than the other and is the primary entrance.
The secondary access point to the concourse level, just 40 m east from the main entrance, is closed to the public.
