Active Lateral Suspension (ALS)
Two functions in one hard ware1) Keep carbody in centred position in curves→ Wider carbody possible→ Better cross wind stability
⇒ Improved lateral ride comfort by avoiding bump stop contact⇒ Possible to run at high speeds in curves2) Improve lateral ride comfort⇒ Same ride comfort at 250 km/h as without
active lateral suspension at 200 km/h
+25%
Wider carbody
3,6 m in Gröna Tåget, if required
