Banked turns and why tracks tilt
Tilting the track aims lateral force into the seat — instead of shoving you sideways.
In a flat turn, lateral G shoves you sideways into the restraint. Banking tilts the track so the normal force from the seat points more through your body, reducing sideways whip.
Ideal banking matches speed — slow trains in a heavily banked turn may feel oddly pressed; fast trains in flat turns feel snappy.
Over-banked transitions at wrong speeds cause head knock — a design and maintenance issue, not something riders fix with posture.
Watch how modern steel curves twist into bank gradually; that easing is deliberate force management.
