Hello - some of the old l&l railroad that you've re-tagged as track road is totally overgrown/eroded and has no currently passable right of way.  Mostly, I'm referring to the area around the csx main line in tewksbury.  Also, the old l&l right of way north of that track is super narrow/single track and has no usage from motor vehicles.  I think path is a more accurate tagging.
