Passenger cabin architecture for a 1000 km/h vacuum-tube hyperloop pod. Seat system, smart-window information display, ambient lighting, and material palette — designed for serial 6-seater capsules.
Zeleros is a Valencia-based hyperloop company developing vacuum-tube transport: pressurised passenger pods that travel through partial-vacuum tubes at near-aerospace speeds. IDMR was brought in to redesign the passenger cabin interior — the experience that has to feel calm and intuitive while moving at 997 km/h with no external view.
The brief was to define an interior architecture that solves three competing problems at once: a narrow tubular volume (no high ceilings, no wide aisles), the absence of real windows (replaced by full-surface displays), and the need for an air-travel-grade safety language (belts, restraints, overhead signage) without the visual heaviness of a commercial aircraft cabin.
The solution: a hybrid seat system — front rows are individual reclining pods (sleeping mode, similar to first-class long-haul), rear rows are upright belted seats for shorter hops. The fuselage skin doubles as a continuous OLED window strip showing virtual landscapes, route, speed, and ETA. Walnut floor and warm-cream upholstery counter the technical austerity of the curved white panels.
Pipeline: Rhinoceros for surfacing, exported to Unreal Engine for real-time visualisation and lighting studies. Material work in Substance. Some exterior pod renders shown below give context for the cabin shape and scale.
The cabin is organised around three seat archetypes — recliner pods at the front, upright belted seats at the back, and a transition row in between — all sharing a single material palette and a continuous OLED window band that wraps the full length of the fuselage.
An animated walkthrough of the cabin and exterior pod system — produced in Unreal Engine, showing how the OLED window content shifts as the pod travels through tube sections, and how the seat zones transition into one another.
The pod itself runs in a partial-vacuum tube elevated above the landscape. Renders below give scale and material context for the interior brief — the cabin lives inside that black aluminium cylinder, suspended on concrete pylons across salt flats, snow, grassland, or urban infrastructure depending on the route.
Zeleros is a Valencia-based deep-tech company developing hyperloop transport — high-speed, energy-efficient passenger and cargo capsules running in partial-vacuum tubes. They've been pioneering the technology since 2016 and run one of the most advanced sub-scale propulsion test campaigns in the field.
