  • Characteristic light lines differentiate the identity and clearly mark the respective platform space of each of the three new stops: Horner Rennbahn, Stoltenstrasse, and Dannerallee. The graphic line structure uniformly divides and structures the space, and provides rapid recognition and orientation for passengers.
    This design accentuates the different geometries of the three station rooms: a single-track stop with side platform (Horner Rennbahn 1), a double-track stop with side platform (Stoltenstrasse) and a curved central platform (Dannerallee). In architectural contrast to the high-quality platform area, the walls and ceilings of the track areas are left largely raw and untreated. The raw concrete is refined and individualized by means of homogeneous, discreet monochromatic track lighting.
    The color of the lighting at each station is derived from the characteristics which influence the surrounding urban space, and forms the backdrop for station-specific projections:
    – Sun yellow (horse racing), at Horner Rennbahn;
    – Green (trees, with reference to the memorable tree avenue) at Stoltenstrasse ;
    – Blue (underwater world, with reference to the proximity of the Schiffbeker recreation area) at Dannerallee.

    The access areas and distribution levels at each station are subtly, indirectly illuminated with the same color as the track area lighting at the platform level. This facilitates orientation, accelerates the passenger flow, and forms the design link to the urban space.
    The urban localization of each stop is expanded by using white light to project selected motifs and information onto the track-space walls, further engaging and informing the passengers. Static, moving and interactive projections are conceivable, recording the number, position and movement of the passengers and creating a playful dynamic interaction of the passengers with the virtual environment. For example, information about local or Hamburg-specific events or weather information can be displayed. The waiting time becomes a shared experience and a temporary smartphone break. When a train arrives, the images and information disappear and ensure distraction-free disembarking and boarding.
