At least three people were killed and around 50 others injured when a Deutsche Bahn Regional Express derailed near Riedlingen in Baden-Württemberg on 27 July, according to ARD. The train was carrying about 100 people when it left the tracks in the district of Biberach, turning an ordinary regional journey into a major rail disaster.

Among the dead were the driver and another railway employee, the report said. That detail matters because it shows the derailment did not only kill passengers; it also killed members of the rail operation itself. Roughly 25 of the injured were reported to be seriously hurt, making this a large-scale emergency rather than a contained accident.

The derailment happened around 6:10 p.m. after severe weather had moved through the area. The German Weather Service said intense thunderstorms brought 30 to 40 liters of rain per square meter in a short time. Officials said investigators were checking whether a landslide or the heavy rain played a role, but the exact cause was still unknown. The gap between what is known and what is suspected is important: the weather may be relevant, but it was not yet proven to be the trigger.

The train was on the RE 55 line from Sigmaringen to Ulm when it went off the rails. According to the report, some carriages slid into one another and came to rest in a slope. Photos and video from the scene showed overturned and damaged carriages, trees knocked down and rescue workers climbing over the wreckage to reach trapped passengers. Those images underscore how violent the derailment was even before the rescue operation fully began.

Emergency crews had to work through the night to free the injured and prepare the derailed cars for removal. The Bundeswehr? No, the report specifically said the technical relief service and specialists for rail accident investigation were involved in the response. That broad response tells us that the scene remained unstable and under forensic review long after the initial crash.

The incident also had immediate transport consequences. Deutsche Bahn said rail service between Munderkingen and Herbertingen was suspended, with replacement buses to run on Monday. That kind of disruption is often an early indicator of how severely a line has been affected: the train cannot simply be moved, and the infrastructure must be checked before service can resume.

Political leaders expressed condolences, but the key question remained the cause. If heavy rainfall or a landslide is confirmed, it will sharpen debate about extreme weather and rail safety. If investigators find another explanation, the focus will shift elsewhere. For now, the confirmed facts are enough to show the scale of the loss: three dead or more, about 50 injured and a regional train wrecked in southwest Germany.
