Fitchburg Line on the eve of change

One of Boston’s oldest historic lines, Massachusetts Bay Transportation Authority’s Fitchburg/South Acton Line between Boston and Fitchburg (built in 1845) is undergoing some major changes, with new station facilities, more double track, new equipment, and a 5-mile extension of service to Wachusett. Trains magazine brings you all the details in its December 2013 issue.

Photographer Tyler Trahan set out to document the line during this period of transition. Here are some of the photos he shared with us. And pick up the December 2013 issue of Trains for the latest details and information on what’s ahead.
