Among different modes of transportation, railway transportation offers reduced travel time, dependability, and excellent energy conservation. Invariably, this mode of transportation plays a vital role not only in the transportation of goods and commodities but also helps in the passenger itinerary. Many technological developments have ascended in the field of railways but healthcare is a major concern. Internet of Things(IoT) is a revolutionary technology that is being widely used to integrate advanced medical resources thereby offering effective health care services to human beings in an effortless way. In this project, we are proposing a controller-based technique to give first aid support in case of emergency, to the patients who are in immediate requirement of medical assistance. The abnormality is detected with the help of wearable sensors. Once the abnormality is detected, the first aid system is triggered by life. The information is transferred to the loco pilot who is in charge of operating the train and the nearest station. Thus, with the help of this system, we will be able to save the life of patients in case of an emergency during transit.
