Salem Ma. has two or three track remnant on Bridge St., that were occasionaly used to stage / store the trains that serve the Eastman Gelatin plant and the few remaining industries over there in Peabody., or they did until that tank car sprung a leak some time back. Then everybody got their panties in a twist, and I haven't seen cars there very much at all.
The upper Salem yard is still partially in place, but almost nothing remains in use.
Its too bad....I can remember riding my bike from Salem to Swampscott in the late '70s/ early '80s to watch the freights head back towards Boston and points west. Usually three assorted B&M Geeps and on occasion, fifty or more cars.
Lynn also once had yards, adjacent to the G.E River Works, but all that's left now is a short, stub-ended on the inbound side of the Commuter Rail tracks, that the "T" uses for MOW purposes. The other side was piled full of construction debris ages ago.
