What if you could get from Worcester to Boston quickly? What if you could get all the way across the state in under two hours — and not drive? That's what's on the minds of some Massachusetts representatives in Congress.

Sen. Ed Markey, Sen. Elizabeth Warren and Rep. Jim McGovern re-introduced their BRAIN TRAIN Act this week, with the goal of building a passenger rail service that would connect local economies with larger cities and help curb commuters' carbon footprint in the process. Is there enough political support to build it? Chris Dempsey of Transportation for Mass. and Karen Christensen of the Western Massachusetts Rail Coalition joined Adam Reilly on Greater Boston to discuss.

"This is arriving at a really good time," Dempsey said about the legislation. "We know that we have in the White House a supporter of rail — Amtrak Joe, who rode Amtrak into Washington, DC for most of his career."

"Most Americans don't have passports — most Americans will never have ridden a train," Christensen said. "They don't know what a train is like because they disappeared 50 years ago."
