    "Living n Needham and commuting to the city is very straight forward. The rail line is dedicated to the Needham commuter rail, the line ends/originated in Needham, and there are 4 stops in the small town. I walk 5min from my house to the train and get off at back Bay to walk just another 5min to my office. Delays are limited due to the fact that this rail line only serves the Needham line."
