Marlboro station feeds into the Sandton and Johannesburg CBD areas. The station consists of semi-open platforms as well as park and ride, bus, drop-off and short term facilities. The station is designed to make extensive use of natural ventilation.

The floating waveform roof over the concourse gives the architectural structure a sense of dynamism and is supported by large steel structural elements that are reminiscent of acacia trees. The tree structures suggest tranquillity and shelter.
