Overview
- Emergency crews stopped and evacuated an intercity train on the Gäubahn near Böblingen after passengers and staff reported an unusual odor on Tuesday.
- Police, fire and medical teams closed platforms 4 and 5 and moved people to safety while firefighters entered the affected carriage with gas detectors.
- Detector readings registered a possible ammonia signal but fire officials said that result is preliminary and does not prove the substance was ammonia.
- Responders collected the unknown liquid, packaged it for safe transport and ventilated the carriage, and the on-scene operation wrapped up at about 21:00.
- Two passengers reported respiratory complaints but no serious injuries were recorded and authorities say lab analysis and a follow-up technical investigation are still pending.
