The maximum bending moment in a simply supported beam due to a train of wheel loads occurs under one of the wheel loads. This is because the bending moment is influenced by the position of the loads, and the maximum value is reached when one of the loads is positioned in such a way that it maximizes the bending moment, typically near the center but not necessarily at the exact center.
