Railway engineering with 40 tunnels and 75 bridges 🚂

The route of the Tren dels Llacs is an example of railway development adapted to complex terrain. The 40 tunnels and 75 bridges were designed to overcome slopes and ravines of the Pre-Pyrenees. The speed is slow, allowing appreciation of each structure and the surrounding landscape. The historic trains, from the mid-20th century, preserve original mechanical systems, while the panoramic ones offer large windows to observe the journey. There is no high technology, but the functionality is effective.

Four lakes and a carriage with manual air conditioning 🌞

The train passes by four lakes, but don't expect to swim in them. The historic carriage lacks air conditioning, so in summer the ventilation system consists of opening the window and hoping for a breeze. If you travel on the panoramic one, the sun will accompany you like another passenger. That said, the tunnels offer a temporary respite of shade. A perfect plan for those who long to travel like in 1950, sweat included.
