Can't answer the question, but to clarify: the B&A is the Boston and Albany; BAR is the Bangor and Aroostook.
There will be a lot of old former B&A (Bangor and Aroostook) employees that take exception to that. The railroad was traditionally "the B&A." I believe the BAR (I've heard it pronounced both "the bar" and "the B-A-R" in the industry) was a much more recent nickname (the 60s?), based on the railroad's reporting marks.
I think I'm correct in saying that the loss of potato shipping was directly responsible for the BAR's abandonment of its main line between Houlton and Van Buren.
It's been years since I've been up there, but in the late 80s there were still a lot of old potato sheds with railroad loading doors along the abandoned right-of-way. Probably still there. And as Ithink of it, there was some guy on Route 1 (near Mars Hill?) who had a whole bunch of railroad "junk" in his yard - old switch stands, slow order/speed signs and even a motor car?
Maine is the largest producer of blueberries in the world.
407, I had to look that one up, as I now live in the Midwest and NEVER see Maine blueberries. In 2005, Michigan was the leading producer, followed by Maine... and in common with potatoes, Maine's blueberry production has waned over time. Meanwhile, New Jersey and Oregon production is growing dramatically.
