The Gotthard Base Tunnel, at 57km the world's longest railway tunnel, will go into operation in 2016, five years after final breakthrough took place. Since 2009, installation of the railway systems in the tunnel has proceeded in parallel with final excavation and construction work. The first pilot train runs took place in mid-December 2013 at speeds of up to 220km/h on a 13km section between Bodio and Faido. In 2019, the flat route through the Alps is scheduled to be completed with the Ceneri Base Tunnel. More than 70% of the 15.4km under the Ceneri has been excavated so far.
