Pretty often... Sorry... You only lose one train line being after Mineola and thats the oyster bay line...

Now... if it is in Carle Place and Westbury the tracks are raised over there (they aren't in Mineola) which means they don't need to honk the horn when passing thru becuase they aren't at street level... that will def minimize the horn sound... but you will still hear the actaul train...

To me the horn is the worst part... we live near a crossing section so thats all we here... remind me not to have an open house during peek hours heehhe LOL...

Def go look at the house or hang out around the house either between 7:30-8:30 am or 5:30- 6:30pm see if you are ok with it.

Good Luck!

FM if you need any other info...
