Northern Tier Passenger Rail

Northern Tier Passenger Rail (abbreviated NTPR) is a proposed intercity rail project in the U.S. state of Massachusetts that would restore passenger service along the Northern Tier corridor, which could connect North Adams, Greenfield, and possibly Albany to Boston. The line would connect Berkshire, Franklin, Worcester, Middlesex, and Suffolk counties in northwestern Massachusetts with North Station.
