North-northeast of the Zirler Berg a particularly winding section of the Karwendel Railway with many tunnels runs over the Seefeld Saddle roughly parallel to the Seefelder Straße. The line runs from Innsbruck via Seefeld and Mittenwald to Garmisch-Partenkirchen and has several stations or halts including Reith, Seefeld and Scharnitz. East of the mountain the railway enters a wide curve over bridges and through tunnels on the south flank of the Rauenkopf and southwestern side of the Brunstkopf, crossing the Schlossbach.
