I have a 3800 sq ft 2story home made by Lennar homes. Supposedly Energy Star / Double pane windows etc.. The home is in a cul-de-sac and the back of the home faces the train tracks. The tracks and crossing is a mile away. Its not so loud that I can't hear my self think but it loud as an annoyance almost like a car alarm down the street. I worry that my daughter would wake up from the noise. I wish there was more i could to do to stop this but if i can soundproof the exteriror rooms facing the train i think it would help. The top half of the home have hardiplank backing and possibly this is why i'm hearing more noise than i would downstairs which is brick. there has been more activity lately and wish ppl would get toghter get some type of quiet zone created so that these ppl are not honking at 3am!!
