It sounds like CSX is returning the old MEC back to what it was before Guilford took over. The old MEC just like the old B&M had 40 mph freight and 60 mph passenger lines. Then GTI took over and that was the end of it all. I saw on a video recently that CSX is also putting back the yard at Barbers, a small yard just outside Worcester located next to I-290. This was a pinch point, due to the tunnel under the medical center located there, that has gotten worse since the "Worcester Main" between Ayer and Worcester became a busy route again now that CSX has taken over.I'm out of Waterville now and haven't ventured past Rigby for about 6 months, so most of the recent information on the Portland sub is from other employees and bulletins, and the like. The other day, I was working with an engineer off the Rigby board who is not a railfan hater (one never admits to being a railfan as an employee) and we had a good discussion on the improvements as we trundled up the Hinckley branch. Speaking of which, it is weird to fly through Belgrade along the lake at 40 past all those camps (camp is local parlance for a summer home or cottage). [EDIT] I forgot to add that there was a newspaper photo of the B&ML yard in Belfast that made the yard look terrible (low angle telephoto shot), and this was used as the main photo for a article on the state of Maine railroads back in the 1980's.
I remember seeing that photo. The unfortunate part is this yard ended up looking like this thanks to a developer and NIMBY wanting the waterfront for condos and expensive tourist traps that I don't think ever materialized.
