“Based on how poorly Massachusetts manages train and subway systems,” a friend remarked the other day, “now seems like a good time to make a huge upfront and long-term subsidy commitment to linking up over the border.”

He was kidding, of course.

But the current and longstanding financial and mechanical woes of mass transit in and around Boston should be instructive for Granite Staters as the incessant push for costly commuter rail in southern New Hampshire continues.

Its latest vague and misleading pro-train “poll” having been sliced and diced by thoughtful analysis, its champions continue to ignore the facts.

They continue to insist that spending more millions of taxpayer dollars on the subject is a good thing.

The poll in question didn’t ask respondents if they would be for commuter rail here given the likely high cost to taxpayers. It merely asked people if they favored commuter trains. Ignoring the big elephant in the room is just what rail proponents did after the Josiah Bartlett Center exposed the poll as worthless. Never mind that, they said, we want trains.

Well, let them go to Massachusetts and ride them, if they are working that day.

Another fare hike is in the offing for the MBTA, even as Boston’s mayor shouts “no” unless and until long-promised fixes made.
