First Law.
Your inertia (Newton’s 1st law) keeps you at rest when the upward normal force from the rail balances gravity so the net force is zero. When the rail breaks that upward support disappears, the net downward force (gravity) accelerates you into the water. (The rail’s upward force exists because of action–reaction — Newton’s 3rd law — but the reason you didn’t fall was the balanced forces / inertia described by the 1st law.)
