I think the reality is that how loud the trains sound will depend on the weather - which way is the wind blowing and how high is the humidity.

I formerly lived 0.3 mile from an interstate, separated by the rest of the homes in my subdivision. Of course, the motorcycles and semis were the loudest vehicles. If we were downwind from the interstate and the humidity was high, they sounded like they were in our back yard! If were we upwind, they weren't even noticeable.

The same was true for a railroad track that was 0.6 mile away.

As everyone has said... ain't no big deal.
