Forge Park/495 station
Under the yellow sign, another sign indicates "end of automatic block signals" — beyond Forge Park, the line operates on train order control. The MBTA recently took ownership of the line from CSX after leasing it for a decade; I believe freight customers are now switched out of Grafton by the Grafton & Upton.
Franklin station
South of the platform and through the ... wide underpass is a switch. The diverging route, about a quarter mile farther south, continues on to Forge Park and ultimately Milford, while the straight-ahead route serves a few remaining freight customers for another mile and is then rail-trailed. Note the absence of a mini-high here: this station is completely inaccessible.
Franklin station
OK, here's the deal with thr platform: this used to be a two-track station. At some point, probably when the line was extended to Forge Park, the MBTA lifted the second track and just duped several yards of hot-mix on the trackbed to lengthen the platform so it would be full-length, although how they got away with not making it accessible at the same time I have no idea. The line down the middle of the platform is the edge of the original platform, which was shorter.
Norfolk station
Here we see the first signs of construction on the Franklin Line Double Track project, which was suspended in late 2020. The three-phase program was to restore most of the original double-tracking between FRANK and SPRAGUE interlockings. allowing for 35-minute peak headways on the line. On the other side of the white fence is a new development of 32 single-family detached condominiums, with town-owned senior housing off to the northwest.
Norfolk station
The Franklin Line Double Track project proceeded far enough to have graded the trackbed through the station. Because the project was implemented by Keolis, there's not a lot of information available, and I can't find anything detailing whether the project includes a platform to serve the second track.
Norfolk station
Looking across Route 115 at the southern end of the new double-track segment, which runs 3.3 miles north to the previous end of the passing siding at WALPOLE WEST interlocking. Google's aerial maps haven't been updated so I don't know how complete the track segment was before work was halted.
Walpole station
Two legs of the full diamond interlocking between the Franklin Line and the Framingham Secondary; this track handles traffic from the Franklin Line heading towards Foxborough, Mansfield, and Middleborough. Because of the station platform placement, Foxboro trains cannot actually serve Walpole station. (For many years, Foxboro event trains would pull past Walpole and reverse into the other branch of the wye, because the MBTA did not want to fix the switch leading to this track.)
Walpole station
A lot more rail and ties for the double-track project take up space in a parking lot for CSX employees working in the yard on the Framingham Secondary just on the other side of the Franklin Line. The double-track was to have continued north from Walpole to Norwood in the final phase of the project.
Plimptonville station
Looking norith up the line towards Windsor Gardens, note the abutments for the overpass clearly were built for a second trackway, now blocked off with sawhorses. If Plimptonville is closed, it's a fairly easy task (albeit expensive) to restore the second track through here, as was planned before the pandemic.
