Boston Green Line Extension railfanning inside a Mansfield sandwich. 

We start the day at the popular trainwatching location of Mansfield, Ma on Amtrak’s NE Corridor.  We then head into Boston and do some Railfanning of the new Green Line Extension.  We ride on the extension in both directions which parallels the Lowell Line Commuter Rail. Amtrak’s Downeaster trains use this as well, and we see trains of both the T and Amtrak.  We finish the day railfanning at Mansfield again before I head for home.  Some interesting locomotives will be seen during the course of this day.
