It is simple. Firstly, you must stand keeping your feet shoulder length apart and the feet must be diagonal to any side of the vehicle (it can either be perpendicular or parallel) and needs to face the direction of inertia.

Standing on a moving train in 2026 requires a specific physical technique to ensure safety and balance, especially during acceleration and braking. The most stable position is the "surfer's stance," where you stand with your feet shoulder-width apart and perpendicular to the direction of travel. This allows your knees to act as natural shock absorbers for lateral swaying. You should always maintain at least one point of contact with a handrail, strap, or vertical pole; relying solely on your balance is dangerous during emergency stops. Avoid leaning your full weight against doors, as they are mechanical and could fail or cycle open. If the train is exceptionally crowded, try to stand near the center of the car rather than the "articulated" gangway between cars, as the Gangway experiences more violent movement. For long commutes, slightly bending your knees and engaging your core will prevent lower back fatigue and reduce the risk of falling if the train hits a sudden curve or "track gap."
