The Cleveland Circle branch loops through the yards
across Beacon St. near the last stop in this scene. The track
trailing off near the lower
left corner of the photo is a non-revenue connection to the Boston
College (B) branch, which runs not that far to the north.
The Riverside (D) branch is even closer, just a block or two away, a bit to
the south. Non-revenue trackage connects all three lines in this
area to permit yard access.
