Correct; Dragon receives
nothing by rail anymore. The petcoke is trucked in from Searsport. There may have been some shipped in by rail for a short while right after the kiln was changed over, but I think having to cut wet/frozen fuel out of the cars with an air lance was deemed counter-productive. As far as I know, they don't mix perlite in their cement.
Dragon did at one time receive gons of "mill scale," mostly scrap metal, which was used as flux in the kiln. I think that traffic went away when the coal loads did.
Over the years, Chemrock/Dicaperl's perlite has come in covered hoppers with various reporting marks, most recently ATSF/BN/BNSF. Ten-plus years ago, there were some cylindrical LOs, mostly SLC (San Luis Central) reporting marks.
The NAHX cars and the larger DPCX "Flexi-Flo" (nee
NYC, ex-PC/CR/MDTX) cars used to go up to Dragon's facility in Windsor, QC; I'm not sure if they still do. The GATX "whalebelly" cars usually are on the shuttle to the Rockland waterfront, but I've seen them going to/from Brunswick, too. Much of the westbound traffic is for Tresca Bros. in Millis, MA.
Dragon has just come back online from winter shutdown.
If Dan Comick stops by here: Re the video, the Rt. 215/Mills Rd. crossing is in Newcastle. The Rockland Branch doesn't go through Damariscotta, but that grade crossing is sort of a boundary of Damariscotta Mills. "The Mills" is just kind of a neighborhood in Nobleboro and Newcastle.
