I have a track at the back of mine & yes you get used to it,
Some of the trains slow or stop as they approach the station
So you hear the odd squeal,or engine noises
As I write this I couldn't tell you if a train has passed today
A couple of times a week we have bulk cement carriages going past 20+ of them so once they've slowed there's a bit of noise to get them up to speed again.
think of the times you've walked in a restaurant that has music playing & how long is it before its just a bit of background noise that you don't really notice...
When I was a kid I stayed at a cousins house that was next to a fire station, bells going off,main doors opening, cab doors slamming, engine noise & blues & twos going didn't sleep the first few times, then didn't bother me.
Or the other option turn the TV up
Will try & get some vids & hopefully upload them.
