secondary line status.
I find this a
very interesting statement for a series of different reasons.
In particular, do you have a sense as to why GRS chose the Back Road over the Lower Road when they rationalized the freight main lines in the 80s? The Back Road actually has one of the steepest grades on the entire MEC system from Winthrop to Readfield, while the Lower Road could accurately be describe as a near "water level" route.

the ABS mostly discontinued while it was maintained intact on the Low Road.
First and foremost, I can certainly testify to what would almost without a doubt appear to be the fact that the Lower Road's ABS signals were maintained
very late into the Maine Central era (if not well into the Guilford and part of the MDOT/Maine Coast era as well). I
believe that I have actually seen one of the signals working one time when Maine Coast was running the line.
Second, I also find it interesting to know that the Back Road did in fact have some kind of "full" ABS installation at one time, as opposed to the "islands" we see today. Given the MEC's historical freight volumes this would seem to follow but I think only one or two other people have ever mentioned this before and even then perhaps only obliquely.

I have also noticed the 112# stick rail in some places with stamp dates ca. 1943 (Lackawanna). Can you or anyone else speak to when the 115# upgrade was conducted? It seems as if there may have been some major trackwork conducted in the late 60's and early 70's.

Thanks for the great perspective!
