As of 2016[update], it was planned to run under the Grimsel Pass and link the Zentralbahn at the north end with the Matterhorn Gotthard Bahn at the south, and its construction is scheduled to begin in 2027.
[4] The total length of the new Grimsel Line (German: Grimselbahn) route containing the tunnel would be 21.75 kilometres (13.51 mi).

Travel time between Meiringen and Oberwald would be approximately 38 minutes—a reduction of three hours.
