If an ambulance is needed due to an injury in the subway, what should train operators notify first?

In the event of an injury in the subway that necessitates an ambulance, the train operator's first priority should be to notify emergency medical services. This is because emergency medical services are specifically equipped to respond to medical emergencies, providing the necessary care and transport to injured individuals. They possess the training and resources required to manage various medical situations effectively.

While notifying the transit police department, fire department, or local hospital may also be important, the primary concern in an injury situation is to ensure that medical assistance is on its way as quickly as possible. Emergency medical services can coordinate responses and, in some cases, may involve the police or fire department if further assistance is required.
