CAT
Vending Machine

I had the opportunity to design the vending machine for the CAT (City Airport Train) in Vienna. The CAT is a high-speed train that connects Vienna’s city center to the international airport.

While the interface and screen layout were predefined, my role focused on designing the outer shell and overall formof the machine.

Research & Sketches

I began with formal research and sketching, exploring how the machine would fit into its environment—considering placement, visibility, facing direction, graphic application, and user orientation within busy spaces like the airport and train station.

Concept Development

After exploring multiple ideas, I developed three design directions:

Concept 1: The Folder

To stand out in a visually busy environment, this concept introduced a tab-like extension that signals the machine’s function. The shape also allows multiple machines to be placed side by side while maintaining strong individual visibility.

Concept 2: The Tripod

This concept transformed the machine into a mini-kiosk, improving visibility through a larger presence. The three-sided structure provided space for advertising and train schedules, turning the machine into a multifunctional info point.

Concept 3: The “C”

This was the selected concept, inspired by the CAT logo and the silhouette of the train itself. The “C” shape offers a curved, folded form that enhances both visibility and branding. Its flexibility allows for wall placement or standalone use, with large surfaces for clear graphic integration.

The footprint of the machine is based on the CAT logo shape 

The design allows to orient the machine towards passengers main flow

The prototype was built in the ÖBB workshop, using a single sheet of metal to wrap the entire structure. I was closely involved in verifying that the details and finishes matched the design intent and 3D plans.

Final Product

Around 20 machines were produced and installed at Wien Mitte station and Vienna International Airport. The final design balanced functionality, strong visual identity, and environmental integration, making the machines both practical and iconic.
