The tunnel reaches a maximum altitude of 1,650 meters above sea level.
Construction required the excavation of approximately 1.7 million cubic meters of rock.
The project was inaugurated in 1999 to resolve the winter isolation of the Lower Engadine.
Ventilation shafts were integrated specifically to manage exhaust fumes from the transported vehicles.
The tunnel is bored through complex geological formations including gneiss and limestone.
It significantly reduces travel time to tourist hubs like Scuol compared to road travel over mountain passes.
The tunnel system includes a safety gallery for emergency egress along the entire length.
The Vereinatunnel is the longest meter-gauge railway tunnel in the world, stretching 19.042 kilometers through the Swiss Alps. It serves as a vital rail-based car transport link connecting the Prättigau region with the Lower Engadine valley. The tunnel bypasses the high-altitude Flüela Pass, providing a reliable year-round transit route between Klosters-Selfranga and Sagliains. Passengers remain inside their vehicles while the Rhätische Bahn (RhB) operates the shuttle service. It is a critical component of the Rhaetian Railway network, facilitating logistical efficiency in mountainous terrain. The tunnel was engineered to withstand high pressure and features advanced ventilation systems to support car transport operations.
The loading platform at the Selfranga terminal offers the clearest view of the train formation before entry.
Check the RhB website for real-time load status to avoid long queues during peak travel days.
Ensure your vehicle is in good condition, as the enclosed tunnel environment requires reliable performance.
Follow all safety instructions provided by the loading personnel, especially regarding engine operation during the transit.
Attempting to drive through the tunnel yourself, as it is strictly a rail-based transport service; always stay with your vehicle on the train.
Operates year-round but may experience temporary adjustments during extreme weather or maintenance periods.
Turn off engines promptly when instructed by loading staff and avoid exiting the vehicle while the train is in motion.
