if you want to hear a train approaching from far away, why is it more

1.	if you want to hear a train approaching from far away, why is it more conveient to put the ear to the track
Answer» Answer: it is because track is MADE up of solid IRON which is a metal and metal is CONSIDERED as a BEST sonorous that's why we are able to hear the vibration of a highly SPEED train from far apart..
