In case of a malfunction during travel, how should the train operator respond according to procedures?

Engaging the emergency brake is the appropriate response to a malfunction during travel. This action is crucial in ensuring the safety of all passengers and crew on board. The emergency brake is designed to bring the train to a halt quickly, preventing further complications or potential accidents that could arise from the malfunction.

In emergency situations, every second and every decision count, so stopping the train helps to contain the issue and allows for necessary assessments and corrections to be made safely. Additionally, it is important to follow protocols that prioritize the safety of everyone involved.

Other responses, such as adjusting speed and proceeding, continuing to the next station, or checking for passenger complaints, do not adequately address the immediate danger that a malfunction can pose. These could lead to escalating the situation and risking harm to passengers, which is why the emergency brake should always be the first step in any emergency response related to operational failures.
