Today, 8-31-12, looks like major tie replacement has started in the Mattawamkeag area. Piles of ties have been placed along the tracks as far as the Lincoln / Winn line where the tie train was found. Atleast two tie cranes were seen back along the line placing the ties ready for the tie crews. More MOW equip. was seen in the yard at Keag. along with a large pile of new ties. Could not get a good look at the equip. in the yard as it was behind the many gon's that were there. Looked like new ballast had been spread in areas, esp. on some of the high fill areas, mostly along the shoulder to build that area up. Some rail spotted in places either just replaced or ready to be replaced. New tie spacing was close, looks like major upgrade in this area.
