I'm wary of railroad noise because I've spent many nights across the street from multiple RR crossings where whistles were blowing literally every 5 minutes. However, 1/2 mile is pretty far from "across the street". I'm going to park somewhere near the house and see just how loud the whistles are, but in the meantime I'm being positive. If 4 blocks is what most people will accept, it should be OK because this house is 8 blocks from the crossing.
Thanks again, all!
From the opinion of a Realtor (I always think of how hard a house would be to resell if my client bought it) - 4 blocks is far enough away that it would not deter most people. You, are one of the people who may be deterred. If it bothers you now (enough to post a question on trulia), and you don't own the house, how much will it bother you once you move in?
Just my opinion, absent many details, and trying to help.
The crossing is 1/2 mile from the house. I was there (at the crossing) when a train went by and it was incredibly loud. But I'm wondering how fast the sound would dissipate. I live about 20 miles from there, and it's hard to just hang out and hope a train goes by, but I suppose I could...
