As a result, sound waves travel faster through solids (such as a length of string) than through gases (like air). That is why we put our ear to a person’s chest to hear their heartbeat, and cowboys in old movies put their ear on the railway tracks to sense the vibrations of a far-off train.

The rumbling sound indicates the arrival of train. But by putting our ear to the railway line, we can hear the sound of the coming train even if it is quite far away.

When we put our ear to a railway line we can hear the sound of an?
We can hear the sound of an approaching train by putting our ear to the railway line made of iron or steel even when the train is far away because the sound produced by the motion of train’s wheels over the railway line is carried away quickly by the steel rails than in air.
