Welcome to the neighborhood. I've lived on the same block for 20+ years, a bit farther west towards Chestnut. You will notice the train noise, at first. After a short time, you'll be oblivious to it. I never notice the horn blowing. To be honest, it's not an issue. Those douchebags with the fart cars on Newark will be way more noticeable. Feel free to private message me if you need any information on the neighborhood.
