The noise of trains passing through the intersections in Tucker, GA, or using horns does not bother me. However, recently trains have started parking and idling not even 1/16th mile from our residential neighborhood near the corner of Lawrenceville Hwy and Brockett Road. The low bass, low frequency noise from the engines cannot be blocked, canceled, or masked. It prevents me from sleeping in my own home, and I can't even imagine how loud it is for the houses that are even closer. I have used CSX's complaint for twice, now, once about a month ago and once about two weeks ago.No one has replied. Again, this is a new issue, and I'm not sure why CSX would choose to park and idle engines within sight of homes. It's constant, and quite frankly, it's affecting my health in serious ways.
