Here was video I recorded + photos I took this past Saturday October 3rd, 2020 in Unionville Ohio of NS Norfolk Southern westbound autorack / freight combo 179 lead by NS AC44C6M's #4019 with a Nathan 5 chime K5LA train horn, New #4354 trailing 2nd, New #4345 trailing 3rd, SD40E's #6334 trailing 4th & #6352 trailing 5th.
Note the blue containers. I believe they haul a certain trash.
