What occurs if the direction selector is moved while the locomotive is in a position other than stop?

When the direction selector is moved while the locomotive is not in a stop position, it does not result in any change in movement or operational state of the locomotive. The system is designed to prevent accidental changes in direction while the locomotive is in motion to ensure safety and control. This means that the direction selector will effectively have no impact until the locomotive is at a complete stop, at which point a direction change can be executed safely. Understanding this operational characteristic is critical for ensuring proper handling of the locomotive and maintaining safety protocols.
