The videos from the guy in Mattawamkeag with the camera in his back yard shows how much CSX is investing in this system.
In this latest video -
https://www.youtube.com/watch?v=aK_HjU7V5gA - a few things stand out.
At 10:05 they have a survey crew surveying the as built conditions including culverts.
At 20:46 to the end of the video you see they are removing all the old ties! Also you see engineers inspecting the work.
I'm interested in Mr. newpylong and others who are used to the Pan AM methods reaction especially the tie removal.
Aren't they supposed to just toss them into the woods? LOL
