The tunnel is a single bore twin track. The BLS AG company offers a car transport service through the tunnel, between Kandersteg station and Goppenstein station, for accompanied vehicles. The journey time of approximately 20 minutes, passengers remain in their cars in open sided car transport vehicles. At peak times, the car transport service operates in each direction every 7½ minutes. The new Lötschberg Base Tunnel, opened on June 15, 2007, has been constructed some below the level of the current Lötschberg Tunnel as part of the NRLA (New Railway Link through the Alps) project.
