Testing out the Green Line extension

GOV. CHARLIE BAKER and the current and future mayors of Somerville took a joy ride on a portion of the new Green Line extension on Thursday — a preview of coming attractions as the $2.3 billion project nears completion.

Somerville mayor-elect Katjana Ballantyne, who joined current Mayor Joseph Curtatone at the press availability at the new Lechmere stop in Cambridge, also provided a preview of what is likely to become a common refrain as the Green Line extension opens: How come it took so long?

Ballantyne took out a copy of the Somerville Journal from 2005. On the front page was a picture of her 7-year-old daughter, who spoke out in favor of the project at a meeting attended by former mayor Michael Capuano and then-MBTA General Manager Dan Grabauskas.

Ballantyne said her daughter came over to her after she spoke and asked: “Momma, when can I ride the train? I said maybe when you’re a senior in high school.”

Ballantyne added: “She’s 25 now.”
