Final answer:
When a locomotive hits something on the track, it is important to b. stop and inspect the locomotive, report the incident to the dispatcher, and apply emergency brakes and evacuate the locomotive only if there is an immediate danger.
Step-by-step explanation:
When a locomotive hits something on the track and you're not sure what it is, the correct course of action is to b. stop and inspect the locomotive. This is important to ensure the safety of the train and its passengers, as well as to identify any damage or potential risks that may have been caused by the impact. By stopping and inspecting the locomotive, you can assess the situation and take appropriate actions to address the issue.
In addition to stopping and inspecting the locomotive, it is also advisable to report the incident to the dispatcher. They can provide further guidance and assistance in handling the situation, and they may need to communicate with other trains or authorities to ensure the safety of the railway.
Applying emergency brakes and evacuating the locomotive should only be done if there is an immediate danger or risk that requires immediate evacuation. This should be the last resort when all other safety measures have been taken and there is an urgent need to ensure the safety of the passengers and crew on board.
