The housing will become less affordable unless more density is built. Worcester is already on an upswing (born there and most of my family is there) and more commuter rail access north and west and more frequent trains would really open up Worcester for families as another option, but dense housing would have to follow for it to remain an option. A lot of the quieter neighborhoods (Tatnuck, Forest Grove, etc.) would probably become less quiet. I think that’s fine, but selling residents on that will be hard.
