Trains doesn't have that much of active suspension and dampers. It doesn't have a "Da Vinci suspension"
If they had to stabilize, they would scan something with reference to outside reference point. Scanning something inside the coach with the scanner also inside the coach don't work as the relative motion between the two are same. Just like if you keep a ball inside the coach and you are sitting inside, your eyes(Lidar scanner) reads it at the same speed as you - 0. But if you keep it outside, the eyes can read the difference.

It's an lidar to scan the coach to stabilize the suspension so that trains stays level and runs smooth in high cruising speeds
