They're going to transload on North Station Track 1, and just reach over the fence to grab the logs off the cars. Or maybe Tower A Mainline 8, along the access road! You have no problem with that, right 1118?
If rumors are true that they're trying to pursue Casella Waste, they could unload lower volumes back there. They could also restore the Mystic Wharf Branch up to, but not crossing, Rutherford Ave and transload on about 700' of track along D St if that'd be allowed. They may have to do such a restoration just to access Casella, anyway. Other options might include being able to secure a track in the New England Produce Center (600'?) or Boston Market Terminal (up to 1,300') where it wouldn't impact current ops. There's about 750' of the former Wynn siding that is on MBTA property and along a temporary Wynn access road. There's some more options, but they're even more of a stretch. My bet is that it won't actually be all that close to Boston at all, and perhaps be an additional customer for Greater Boston Terminal (Iron Horse Park).
