Well, here's an update:
Norfolk Depot: rails and ties are down for MOST of the way from just West of Walpole through to just East of Franklin with short gaps between Norfolk and Franklin. One of these gaps is, of course the crossing at Rockwood Street directly adjacent to the station.
Signal masts appear to be complete save likely for last-minute wiring/installation considerations.
Speaking of wiring, the bases for the new crossing protection are in with wiring visible in the center of each. The old electrical equipment box on the East side of the aforementioned crossing remains extant and connected to the new box by a conduit. I assume they've been populating the new box over the past year and swapping functions to the new one. So when they're ready, they'll just need to bolt the new protection to the new bases and remove the old box, then put the tracks down in the road.
The other two gaps seem to be getting shorter, but not with any predictable regularity. I've caught the crews working at Norfolk a few times over the last 2 months or so, but it's strictly "catch-as-catch-can."
So, ... status:
(I wish I knew the track numbers!) New track is as near to "service ready" from Walpole to the crossover East of the crossing at Norfolk, Crossovers are in place at both ends of the station but signals are still oriented for "not in service." At the station it's rail and ties with panel track sections waiting to be dropped in for the crossing, Rails solid West to the Park St OGB, then a gap of less than one mile, then solid the rest of the way to Franklin.
Also: they're bustituiting Walpole to Franklin/FP for work on the doubletracking project this weekend. Bunch of alignment equipment on the new track, but I couldn't tell where they were working on what.
