In this week's Codcast, the folks from TransitMatters (Josh Fairchild and James Aloisi) sit down with Jessica Robertson and Ari Ofsevit, two members of the Allston Interchange Task Force (Ofsevit is also a TransiMatters member) to hash out the West Station issue. All of them believe the station needs to be built at the beginning of the development process, so don't expect a point-counterpoint type of debate. What their discussion reveals, however, is how the debate over West Station has become a debate about the future of the T and commuter rail.
