Railway failures between Kiel and Hamburg: signal box in Elmshorn defective!
On Monday morning, June 23, 2025, an unpleasant incident in Elmshorn (Pinneberg district) caused great unrest on the rails between Kiel and Hamburg. A defect in a signal box led to massive train failures, which were recorded in the DB Navigator from 9 a.m. Loud NDR Both long-distance trains from Deutsche Bahn and regional trains from Nordbahn were affected, which rapidly worsened the situation.
Technicians were quickly on site and worked to resolve the problem. These efforts bore fruit as the problem was resolved shortly after 11 a.m. However, caution is advised: even after normal operations have been restored, individual delays and disruptions are still possible. However, there was no rail replacement bus service, which further complicated the situation.
Affected connections
The outages occurred on several key connections:
- RE 7 und RE 70 zwischen Kiel und Hamburg wurden über Elmshorn eingestellt und fuhren stattdessen bis und ab Neumünster.
- Auch die Verbindung RE 6 zwischen Sylt und Hamburg sowie die RB 61 und RB 71 der Nordbahn waren betroffen.
Due to the signal box defect, many trains were not at their intended location, which led to further delays even after the problem was resolved. The timetable app pointed out that restrictions were to be expected until 12 p.m. from Kiel towards Hamburg and until 12:22 p.m. from Hamburg towards Kiel.
Review of previous incidents
With all these incidents in mind, it is clear that the region's infrastructure needs a better hand in dealing with unexpected disruptions. Passengers can only appeal to regularly inform themselves about current timetables and to remain patient while the railway overcomes its challenges. In the coming days of June and July, rail customers will also have to expect further outages, both on Nordbahn and Deutsche Bahn, which will make planning trips in the region even more difficult.
Information on data protection
For anyone who wants to plan their trips online, it should be mentioned that the Deutsche Bahn website can generally be used without providing personal data. However, anyone who would like to use special services is advised to observe the data protection regulations, which can be found below bahn.de/datenschutz are visible.
The situation in Elmshorn reminds everyone involved in transport, both on the rails and in the digital world, to exercise care and plan so that future disruptions can be handled as smoothly as possible.
