Was able to walk a good part of it in Dec before the snow, the brush had been cleaned out nicely. A few switches still functioning, overall not in too terrible shape. However over the past few days they (Danvers Electric I think) have been pulling up the rails between Pine and Holten streets. If you get a chance to walk it once the snow melts, I recommend it!
Get out and walk the line in Danvers **now** or it may be too late to see tracks. It's a trail conversion that has been planned for years, and seems to have just gotten going with the rail removal.

If you're on facebook you can see their photos from the Pine Street removal that you saw:

That facebook photo page says "Added 21 hours ago" so the work may have just started a few days ago.
