What action should you take when you run over 3 RTS?

When you run over three Route Indicator Signals (RTS), the protocol requires you to stop immediately to ensure the safety of operations and to assess the situation. This action is critical because running over multiple RTS indicates a potential miscommunication or misunderstanding of signals, which could lead to hazardous situations such as collisions or derailments.

Stopping allows you to evaluate the scenario, check for any malfunctions, and communicate with the appropriate personnel to implement the necessary corrective actions. The safety of all personnel and the integrity of the railway system depend on immediate responses to such situations, emphasizing the importance of stopping instead of continuing on or escalating speed, which would further complicate the situation.

Other actions like sounding a whistle, increasing speed, or calling for assistance can be part of a response but do not replace the critical first step of stopping the train to ensure safety and address the issue appropriately.
