The paper presents the methodology to overcome the problem of wildlife animal’s deaths due to railway accidents. Self responding train detection system has been implemented by using high sensitive vibration sensor mounted on track. Vibration sensor captures the data while train crossing the sensor mounted area of track. Sufficient numbers of sensor are deployed before the wildlife reserve area. Arrival of train is sensed before it enters the reserve area by the sensor and information is transmitted towards the receiver placed at the monitoring site. Eventually actuators are activated to generate exasperation sound wave to scatter wildlife animals from the railway track.

Transportation system is phenomenally used for goods as well as public transportation. Eventually railway becomes prime mean for transportation and railway track cover large geographical area in country like INDIA. The extensive network of the Indian Railways passes through several forest reserves, resulting in collisions of trains with a variety of wildlife species, including the tiger and beer.  According to survey given by Mukti Roy & Raman Sukumar on Railway Ecology pp 157-177 states that railway lines cross elephant habitats in several states, with accidents that resulted in more than 200 elephant deaths between 1987 and 2015 . Similarly a 10-month-old tiger cub got killed and another got seriously injured when a speeding train hit them near Kelzar on Gondia-Chanda Fort section in Tadoba region. This news made NTCA to take urgent measures for preventing wild animal mortality due to train hits. NTCA has suggested several measures one being to decrease the speed of train in prone zone. However, a proposal in this regard for Tadoba is pending with NTCA. When it comes to justice for the animals, justice finds hard to prevail. Wildlife animals play vital role to maintain environmental condition for recycling of nature. It is necessary to minimize unfortunate wildlife accidents on railway track. If tracks are layed train cannot be stopped to move on these tracks but alternate arrangement can be done to avoid accident. Wildlife monitoring near the rail track can be one of the solution to the above problem . Alternate solution could be to indentify the train entering the wildlife reserve area before time and alert the wildlife near the tracks. Train detection and wildlife alert system is reliable and simple way to avoid the possibilities of accidents of wildlife . The paper presents train detection and alert system specifically for Tiger and Bors found maximum in the rich TadobaAdhari Tiger Reserve (TATR) area suffering casualties due to train route in the buffer zone.
The paper analyzes three different sensors viz. Accelerometer, shock sensor and vibration sensor for the detection of train. It shows the vibration changes occur in sensor with respective to time. The selection of vibration sensor SW-420 for train detection is a good choice. By using WSN network sufficient number of sensors can be deployed to get information of the approaching train. Eventually sound wave frequency activators are activated to alert wide life animal and distract them from prone zone area of railway track.
