Kallos Royal Park is a complex of two stations, a railway station and a light rail station. The railway station serves (or is planned to serve) as the terminus for the Fryske Line and Elizabeth Line. The light rail station serves as a major junction for the Lilac Light Rail, with trains departing from this station in four different directions. It was built in a style somewhat resembling the Elizabeth Line in London, due to the Elizabeth Line being the first line planned in this location.
The light rail station has 4 west-east oriented platforms, three of which serve trains going west, with the remaining platform serving trains going east. There is also a skipping track on the southern end of the station for trains that do not stop at Royal Park after leaving the LRT Depot station.
The heavy rail station has 2 west-east oriented platforms elevated on top of the station building, serving the Fryske Line. In the future, 2 extra platforms will be built underground to facilitate the Elizabeth Line.
