New two-hourly express trains were introduced that ran between Hamburg and Heide making even fewer stops than IC trains. These trains were aimed at offering travel times of less than two and a half hours from Hamburg to North Sea resorts, such as Büsum via Heide, Dagebüll via Niebüll and Sankt Peter-Ording via Husum. Hourly local trains were introduced, stopping at all stations to Husum. Trains were added during peak hours from Pinneberg to Itzehoe.
