Two things I wonder re: CSX traffic on its New England Division to/from Maine & Beyond:
1. Why is there no observable C&D and/or municipal trash business coming out of Maine headed for landfills elsewhere in the US? CSX trains M424/M425 and M436/I115 routinely haul lots of high sided C&D gons and, on the W Springfield trains, often have blue municipal waste containers, as well. And of course, PAS hauls lots of municipal waste out of Arrowhead and Republic at Ayer. M427 may haul C&D out of Devens re-cycling at Ayer on occasion but I don't see any such traffic east of Ayer (and that includes EDPO/POED).
2. I don't know the volume of traffic coming out of Maine and the Maritimes heading for southern New England via CSX (eg, Irving lumber to SE Mass, cement to Tresca at Millis, sheet rock, etc) but I wonder if CSX would consider blocking such traffic at Rigby for W Springfield and/or Westborough to avoid the round trip over the Berkshires to Selkirk and back?
