The renovation involves updating the interior design of the cars to offer a modern and efficient cafeteria service and an accessible vehicle, with the integration of elevators, PRM spaces, and a PRM restroom. To achieve this, the layout was completely updated, a completely new atrium and cafeteria were created, and the passenger lounge was redesigned with new lighting, partitions, luggage compartments, and cabinets.

Ariño Design carried out the entire project, from the 3D survey (as it was not digitized), the layout, the design, the engineering, its development, virtual reality, and a volumetric model inside the vehicle to be renovated.
