you know why she did,nt heard the voice of train because when train runs it create 120 decimal sound and  when we listen music at high volume,it create same 120 decimal sound as train create  that' why we are not able to hear other sound while listening music. It is very dangerous for us, We should not use earphone while driving or walking on roads. Be extra carefull if you crossing railway track, you can listen music at appropriate place like your home, restruant,park etc but should not listen when you need to concentrate on your other work because your mind get distracted and you cut out from world. Not in our country foreign countries are facing same problem, in britain about 17 people died every year because of this reason.American government is trying to make strict rules to curb deaths.

   At last i just want to say that we are from india where rules are not accomplish easily and followed but we can save our life by stay alert everytime and try to save life of other people by giving them advise.
