The emergency alarm system in the subway serves to alert authorities and passengers of emergencies, triggering a swift response with alarm-bells, steam-whistles, and visual signals indicating the approach of emergency services.
One function of the emergency alarm system in the subway is to alert authorities and passengers of an emergency situation. The loud ring of alarm-bells and the cry of fire, as an example, signal the presence of a potential hazard, prompting an immediate response from emergency services. The appearance of swift-streaking engines and hose-carts, along with premonitory tinkles and colored lights, indicates that the alarm system has been activated and the necessary actions are being taken to ensure the safety of all individuals within the subway system.
The steam-whistle and the solid roll of the train of approaching cars serve to reinforce the urgency of the situation, as they are often synonymous with the arrival of additional emergency personnel and equipment. Together, these various components of the alarm system work in concert to provide quick and effective responses to emergencies, safeguarding passengers and staff alike.
