The Woburn Branch Railroad (known as The Woburn Loop) was a branch line of the Boston and Lowell Railroad ("B&L") that connected the city square in Woburn, Massachusetts to the main line. When the B&L laid out its main line, it respected the wishes of the people of Woburn not to run the line through their town center. Instead, the B&L ran the line through the Montvale, Mishawum and North Woburn sections of the town, bypassing the center.
