I grew up half a block from a freight train line, and you could hear it, but it wasn’t really an issue. Trains have gotten a lot louder in the US recently due to lack of rail maintenance. (Concretely, the transbay BART tube is screeches was above osha safety limits inside the car these days, but was quiet when new. The problem is that you need to grind rails to have a rounded top or they screech (and wear out train wheels), but BART doesn’t bother.
Anyway, noise pollution has a real impact on health, but so does particulate carbon and benzene from freeways. Before moving near a major road, find out what sort of PM 2.5 is typical, and check to see if everything is coated in black dust. If so, and you can afford some other place, move there instead.

I just Googled for <<does bart grind tracks and wheels?>> Plenty of hits indicating that, yes, BART does grind tracks and wheels. > was quiet when new Do you mean in 1974 it was quiet? I tried to Google for any evidence of this and I can find nothing.
- Groxx 3y ago"does not screech horribly" isn't particularly noteworthy, to be fair
- mikrotikker 3y agoI got a friend who did the first grind ever in NZ a few years back, they borrowed the grinder locos from Aussie. Every train driver he talked to commented how amazingly better the rails were after grinding.
