The longest rail tunnel is the Gotthard Base Tunnel, at a length of 57 km (35.4 mi), running between Erstfeld and Bodio in Switzerland, and opened on 1 June 2016.
The tunnel's excavation was completed on 15 October 2010, when engineers working some 2,000 m (6,561 ft) beneath the Swiss Alps drilled through the last remaining rock. The tunnel is anticipated to accommodate up to 300 trains per day.
