The Vereina Tunnel is situated in eastern Switzerland, and at 19,058 m is the longest tunnel on the Swiss RhB/MGB railway network as well as the world's longest metre gauge railway tunnel. In length, it is followed by the Furka Tunnel (15,442 m) and the Albula Tunnel (5,8 km).

Service is based on hourly regional trains between Scuol-Tarasp and Chur, completed every 30 minutes by shuttle trains transporting road vehicles between the two valleys linked via the tunnel and by freight trains. The tunnel is single track, with passing loops (each two km long) in the middle and near the two portals.
