What did the sensors see?
Lateral acceleration · IMU L
Same section · both passagesPrevious · 13:42 · dashed Latest · 14:08
Both traces on the chart · highlight: latest · train A · 104 km/h
Observation: on the same section at similar speed, the latest passage shows a stronger lateral impulse. Cause not confirmed.
