A curtain system may include a track system configured to be mounted to an interior structure of a vehicle. The track system may include three or more track sections oriented in at least two different directions. Each track section may be configured to support at least one curtain suspended from and slidable along the track sections. The track system may include at least one junction fitting interconnecting three or more track sections and allowing movement of a curtain from one of the three or more track sections to either one of two or more other track sections of the three or more track sections. In this regard, the junction fitting and the track sections may define different curtain paths for the curtain.
