At the end trains ran rather infrequently on a very weedy, very slow track. The branch from South Acton was gone south of Maynard long before that, having been abandoned in 1943.
And the route shows it. I mountain biked the route from the site of the Maynard depot west to the point the railroad crossed the Assabet River. The bridges on this line are *long* gone and the abutments are in advanced state of decay.
Recently, I found the interchange track between the Central Mass and the B&M's Marlboro branch. As with most abandoned B&M routes I've investigated, the track is intact ... waiting for a train that will never come. I hope to get pictures of this spot in the near future.
The interchange is interesting because it's sited (shoehorned?) between the CM's overgrade crossing of Rte 62 and that of the Marlboro Branch itself. Both of these bridges are removed, yet isolated track remains.
Returning to Maynard ... I studied the bridge that carries Rte 117 over the canal that brings water to the former Assabet Mill. When the railroad was active, the road took a 90-deg right to cross the railroad. Since it's been abandoned, the upper half has been rebuilt to cross the right of way on a 45-deg angle.
Of note, most of the branch between Maynard and South Acton is intact. This includes a run-around between the route's crossings of Rte 62 (immediately west of Maynard depot) and 117. A switch can be see poking up through the pavement in the aptly-named "Railroad" parking lot for Clock Tower Place (the current name for the Assabet Woolen Mill).
East of there, I'd say at least 80% of the branch is still intact. All of the grade crossings are gone, as is the route's crossing of the Assabet in Maynard (and the fill and, bridge piers). Where the route tied into the main at South Acton is under Rte 27's rebuilt overgrade crossing of the MBTA Fitchburg Branch.
