There are train tracks about 1/2 mile from my house. Why when there are certain weather conditions are the passing trains so much louder than normal?

Answer 1

When the skies are especially cloudy, AM radio signals travel much further than normal. I grew up near Detroit, and I remember that when storms were looming and there was heavy cloud coverage I could pick up WLS from Chicago as clear as a bell.
