BO-1 MEC 507 heads East through Brickyard Interlocking in downtown Lynn, MA with 5 loads for Rousselot in tow. The runaround here was last used to service U.S. Plastics (behind me) and is sometimes used to store MBTA MOW equipment on. This section of the Eastern Route Mainline from GE/Riverworks to Green St. was part of a crossing elimination project undertaken by the Boston & Maine in 1911.
