Massachusetts Gov. Deval Patrick plans on adding at least seven more tracks to Boston's South Station in an expansion project that will cost $850 million. Expanding the station will also require relocating the adjacent U.S. Postal Service’s General Mail Facility. "This not an infrastructure project for an infrastructure project’s sake," said Kairos Shen, chief planner at the Boston Redevelopment Authority. "There are major benefits for the long-term competitiveness of the city."
