The Halligbahn Dagebüll – Oland – Langeneß is a light railway of the State Office for Coastal Protection, National Park and Marine Protection (LKN SH) leading through the North Frisian Wadden Sea from Dagebüll to the Halligen Oland and Langeneß.
From 1925 to 1928 the light railroad with a gauge of 900 mm was built on a pile embankment. After the commissioning of the Hindenburgdamm, the tracks were taken over by the light railroad used in its construction. The Lorenbahn went into operation from 1927. The further connection from Oland to Langeness was probably not completed until 1928.
Initially, the trolleys were driven by sails through the wind, from the mid-1960s they were equipped with gasoline or diesel engines.
Driving is permissive - "on sight" - in any weather. The private carts are partly simple flat wagons that can be equipped with benches or armchairs, or carts that are closed on all sides. These are typically moved with small industrial motors from 4.5 to 9.5 HP. Only the construction vehicles, here exclusively Schöma locomotives with 25 to 65 HP, are heavier and can transport larger loads such as truck trains with basalt stones or larger construction machines.
Hallig residents are allowed to use the dam with their own carts to run errands on the mainland. This private use is only tolerated and is subject to strict rules on the part of LKN and the insurance company. Passenger transport is only permitted for relatives and holiday guests for the Olanders and the Langenessers only for relatives; spontaneous rides are strictly prohibited. Lorry drivers who spontaneously take people with them can have their driving licenses withdrawn by the authorizing authority, Amt Pellworm.
