in 1927 the hindenburgdamm was built. this causeway connects sylt island to the mainland. klanxbüll is the last station on the mainland, before the track reaches sylt; thus is it for people working in the surrounding countryside and on sylt an important park&ride station (chargeable:; 2.50 euros per day). the surrounding populated areas are declared to be prohibited for parking areas, to stop tourists going to sylt from choking the area with parked cars. the station equipment was reorganized gradually in the last years. in 2006 a road bridge was built over the railroad, as before road traffic often had long waits at the level crossing while the gates were closed for trains to pass.
