I’m a fan of the color green, even the shade of emergency/lime green on this Galion Grader. This grader was hanging out the local CSX rail yard. I really don’t have a clue on the age of this machine but it seems to be well maintained. If I had to guess I would say it was nearly 30 years old and quite possibly a hold over from the Conrail days.
It is probably a 1967 T-400. The rounded radiator was replaced by 1968, but the angular cab was not introduced until after 1966, at least based on 1966 and 1968 T-600s I have seen.
