Train chaos: defective signal box hinders the Hamburg-Sylt connection!
An unpleasant technical problem is causing significant disruptions in train traffic between Hamburg and Westerland on Sylt today, October 28, 2025. The reason for these failures is a defective signal box in Hochdonn World reported. The damage occurred in the early afternoon and meant that train traffic between Heide (Holst) and Itzehoe has been no longer possible since 1:15 p.m.
The impact on travelers is clearly noticeable. IC trains between Hamburg and Westerland are canceled, and the regional trains on the RE6 line only run to Husum. Travelers are advised to use temporary alternative local transport connections in order to be able to continue their journey. Train services will be replaced by buses running between Husum and Itzehoe, which can result in additional waiting times of up to 60 minutes Boyen's Media communicates.
Technical problems and solutions
DB InfraGO technicians are already on site to assess the damage. However, the situation also shows that further technical problems in the Heide area due to cable damage on the Eider Bridge are contributing to the current signal box failures. During this time, trains on the RB63 line can only run between Neumünster and Hohenwestedt, and a replacement rail service has also been set up here.
The railway has announced that work on the signal box will continue at full speed, including during the night. A railway spokesman assumes that train services will be able to run as planned again on Wednesday morning. But until then, passengers must continue to be patient and, if necessary, find out about the current situation on bahn.de or in the DB Navigator.
For travelers who want to travel to Husum, the Nordbahn trains are available between Husum and Neumünster, where they can use the connections to the RE 7 line to Hamburg. Despite all the changes and difficulties, there is still hope that the disruption will soon be resolved and the situation will ease for commuters.
In the meantime, the replacement buses are an important solution to getting travelers safely to their destination and minimizing the impact of the signal box defect.
