I can't read what you're writing!!! The train is way too loud!!! Ha, ha!!!
Seriously, I can't tell you if the train will be too loud for you or other people. It's personal taste. Generally, the presence of a commuter rail has already been priced into the value of a property unless the MBTA laid tracks last night and started running trains this morning without telling anybody. So, you are probably going to buy a property for less money because it is situated close to the tracks but don't expect to become a real estate millionaire on the other end by painting a mural of the Fiji Islands on a wall between the house and the train tracks. Good luck, Jon
