MIAS Architects, in collaboration with Leitner Ropeways, has designed the new funicular for the Tibidabo Amusement Park—a technological, sustainable, and cutting-edge train with minimal environmental impact.

The project is the winner of the 2023 Architizer A+ Popular Choice Awards in the Sustainable Transportation Project category.

The new train features a completely revamped high-end design, resembling a glow-worm, with larger glass surfaces on both sides and the roof. These enhancements not only improve the operational efficiency and passenger comfort compared to the previous model but also incorporate enhanced safety systems and facilitate easier maintenance. The utilization of advanced technology ensures minimal environmental impact and CO2 emissions.

The funicular now operates at a speed of 10 meters per second, resulting in a journey time of approximately 3 minutes. The capacity has also been increased. The funicular's design has been completely renewed and personalized, significantly enhancing the experience for riders and allowing them to interact with the attraction. Consequently, the new funicular, named 'Cuca de Llum' (Glow-worm), has become an additional flagship attraction within the park.

The primary structure of the train consists of ultralight aluminum profiles, enhancing energy efficiency, speed, and vibration reduction. Coloured fiberglass covers the structure, further protected by a specially designed reflective coloured particle, ensuring durability and reflectivity.

Achieving a transparent structure for the funicular involved using curved glass at both ends of the train. Unlike typical curved glass, the funicular employs two curved sheets with non-constant variable radii, separated by dehydrated air chambers, to meet high solar efficiency requirements. A separation profile and a desiccant product prevent condensation between the glass sheets.

Passengers can enjoy panoramic views above Barcelona through large windows and skylights from the new spacious trains. Interactive screens and tablets complete the passengers visual experience with educational content about the journey. Riders can learn about the funicular's operation, its history, and that of the park in general. Additionally, they can watch interactive videos and play games on the tablets, providing a comprehensive educational experience centred around the Tibidabo Funicular Amusement Park and the Collserola Natural Park.
